+# AW20216S Driver {#aw20216s-driver}
+
+SPI 18x12 LED matrix driver by Awinic. Supports a maximum of four drivers, each controlling up to 216 single-color LEDs, or 72 RGB LEDs.
+
+[AW20216S Datasheet](https://doc.awinic.com/doc/20230609wm/b6a9c70b-e1bd-495b-925f-bcbed3fc2620.pdf)
+
+## Usage {#usage}
+
+The AW20216S driver code is automatically included if you are using the [RGB Matrix](../features/rgb_matrix) feature with the `aw20216s` driver set, and you would use those APIs instead.
+
+However, if you need to use the driver standalone, add this to your `rules.mk`:
+
+```make
+COMMON_VPATH += $(DRIVER_PATH)/led
+SRC += aw20216s.c
+SPI_DRIVER_REQUIRED = yes
+```
+
+## Basic Configuration {#basic-configuration}
+
+Add the following to your `config.h`:
+
+|Define |Default |Description |
+|-----------------------------|-------------|-------------------------------------------------------------|
+|`AW20216S_CS_PIN_1` |*Not defined*|The GPIO pin connected to the first driver's Chip Select pin |
+|`AW20216S_CS_PIN_2` |*Not defined*|The GPIO pin connected to the second driver's Chip Select pin|
+|`AW20216S_EN_PIN` |*Not defined*|The GPIO pin connected to the drivers' Enable pins |
+|`AW20216S_SPI_MODE` |`0` |The SPI mode to use |
+|`AW20216S_SPI_DIVISOR` |`4` |The SPI divisor to use |
+|`AW20216S_SCALING_MAX` |`150` |The scaling value |
+|`AW20216S_GLOBAL_CURRENT_MAX`|`150` |The global current control value |
+
+### Global Current Control {#global-current-control}
+
+This setting controls the current sunk by the `CSx` pins, from 0 to 255. To adjust it, add the following to your `config.h`:
+
+```c
+#define AW20216S_GLOBAL_CURRENT_MAX 150
+```
+
+## ARM/ChibiOS Configuration {#arm-configuration}
+
+Depending on the ChibiOS board configuration, you may need to [enable and configure SPI](spi#arm-configuration) at the keyboard level.
+
+## LED Mapping {#led-mapping}
+
+In order to use this driver, each output must be mapped to an LED index, by adding the following to your `<keyboardname>.c`:
+
+```c
+const aw20216s_led_t PROGMEM g_aw20216s_leds[AW20216S_LED_COUNT] = {
+/* Driver
+ * | R G B */
+ {0, SW1_CS1, SW1_CS2, SW1_CS3},
+ // etc...
+};
+```
+
+In this example, the first LED index on driver 0 has its red channel on `SW1_CS1`, green on `SW1_CS2` and blue on `SW1_CS3`.
+
+These values correspond to the matrix locations as shown in the datasheet on page 16, figure 16.
+

+SRC += is31fl3218-mono.c # For single-color
+SRC += is31fl3218.c # For RGB
+I2C_DRIVER_REQUIRED = yes
+```
+
+## Basic Configuration {#basic-configuration}

+};
+```
+
+In this example, the red, green and blue channels for the first LED index all have their anodes connected to `VCC`, and their cathodes on the `OUT1`, `OUT2` and `OUT3` pins respectively.

+
+I²C LED driver by Lumissil. Supports a maximum of four drivers, each controlling up to 36 single-color LEDs, or 12 RGB LEDs.
+
+[IS31FL3236 Datasheet](https://www.lumissil.com/assets/pdf/core/IS31FL3236_DS.pdf)
+
+## Usage {#usage}
+
+The IS31FL3236 driver code is automatically included if you are using the [LED Matrix](../features/led_matrix) or [RGB Matrix](../features/rgb_matrix) feature with the `is31fl3236` driver set, and you would use those APIs instead.

+SRC += is31fl3236-mono.c # For single-color
+SRC += is31fl3236.c # For RGB
+I2C_DRIVER_REQUIRED = yes
+```
+
+## Basic Configuration {#basic-configuration}
+
+Add the following to your `config.h`:
+
+|Define |Default |Description |
+|----------------------------|-------------|----------------------------------------------------|
+|`IS31FL3236_SDB_PIN` |*Not defined*|The GPIO pin connected to the drivers' shutdown pins|
+|`IS31FL3236_I2C_TIMEOUT` |`100` |The I²C timeout in milliseconds |

+|`IS31FL3236_I2C_ADDRESS_4` |*Not defined*|The I²C address of driver 3 |
+
+### I²C Addressing {#i2c-addressing}
+
+The IS31FL3236 has four possible 7-bit I²C addresses, depending on how the `AD` pin is connected.
+
+To configure this, set the `IS31FL3236_I2C_ADDRESS_n` defines to one of the following in your `config.h`, where *n* denotes the driver index:
+
+|Define |Value |
+|----------------------------|------|
+|`IS31FL3236_I2C_ADDRESS_GND`|`0x3C`|
+|`IS31FL3236_I2C_ADDRESS_SCL`|`0x3D`|

+|`IS31FL3236_I2C_ADDRESS_VCC`|`0x3F`|
+
+## ARM/ChibiOS Configuration {#arm-configuration}
+
+Depending on the ChibiOS board configuration, you may need to [enable and configure I²C](i2c#arm-configuration) at the keyboard level.
+
+## LED Mapping {#led-mapping}
+
+In order to use this driver, each output must be mapped to an LED index, by adding the following to your `<keyboardname>.c`:

+ // etc...
+};
+```
+
+In this example, the red, green and blue channels for the first LED index on driver 0 all have their anodes connected to `VCC`, and their cathodes on the `OUT1`, `OUT2` and `OUT3` pins respectively.
+
+For the single-color driver, the principle is the same, but there is only one channel:

+# IS31FL3729 Driver {#is31fl3729-driver}
+
+I²C 16x8/15x9 LED matrix driver by Lumissil. Supports a maximum of four drivers, each controlling up to 135 single-color LEDs, or 45 RGB LEDs.
+
+[IS31FL3729 Datasheet](https://www.lumissil.com/assets/pdf/core/IS31FL3729_DS.pdf)
+
+## Usage {#usage}
+
+The IS31FL3729 driver code is automatically included if you are using the [LED Matrix](../features/led_matrix) or [RGB Matrix](../features/rgb_matrix) feature with the `is31fl3729` driver set, and you would use those APIs instead.
+
+However, if you need to use the driver standalone, add this to your `rules.mk`:
+
+```make
+COMMON_VPATH += $(DRIVER_PATH)/led/issi
+SRC += is31fl3729-mono.c # For single-color
+SRC += is31fl3729.c # For RGB
+I2C_DRIVER_REQUIRED = yes
+```
+
+## Basic Configuration {#basic-configuration}
+
+Add the following to your `config.h`:
+
+|Define |Default |Description |
+|----------------------------|--------------------------------------|----------------------------------------------------|
+|`IS31FL3729_SDB_PIN` |*Not defined* |The GPIO pin connected to the drivers' shutdown pins|
+|`IS31FL3729_I2C_TIMEOUT` |`100` |The I²C timeout in milliseconds |
+|`IS31FL3729_I2C_PERSISTENCE`|`0` |The number of times to retry I²C transmissions |
+|`IS31FL3729_I2C_ADDRESS_1` |*Not defined* |The I²C address of driver 0 |
+|`IS31FL3729_I2C_ADDRESS_2` |*Not defined* |The I²C address of driver 1 |
+|`IS31FL3729_I2C_ADDRESS_3` |*Not defined* |The I²C address of driver 2 |
+|`IS31FL3729_I2C_ADDRESS_4` |*Not defined* |The I²C address of driver 3 |
+|`IS31FL3729_PWM_FREQUENCY` |`IS31FL3729_PWM_FREQUENCY_32K_HZ` |The PWM frequency of the LEDs |
+|`IS31FL3729_SW_PULLDOWN` |`IS31FL3729_SW_PULLDOWN_2K_OHM_SW_OFF`|The `SWx` pullup resistor value |
+|`IS31FL3729_CS_PULLUP` |`IS31FL3729_CS_PULLUP_2K_OHM_CS_OFF` |The `CSx` pulldown resistor value |
+|`IS31FL3729_GLOBAL_CURRENT` |`0x40` |The global current control value |
+
+### I²C Addressing {#i2c-addressing}
+
+The IS31FL3729 has four possible 7-bit I²C addresses, depending on how the `AD` pin is connected.
+
+To configure this, set the `IS31FL3729_I2C_ADDRESS_n` defines to one of the following in your `config.h`, where *n* denotes the driver index:
+
+|Define |Value |
+|----------------------------|------|
+|`IS31FL3729_I2C_ADDRESS_GND`|`0x34`|
+|`IS31FL3729_I2C_ADDRESS_SCL`|`0x35`|
+|`IS31FL3729_I2C_ADDRESS_SDA`|`0x36`|
+|`IS31FL3729_I2C_ADDRESS_VCC`|`0x37`|
+
+### PWM Frequency {#pwm-frequency}
+
+The PWM frequency can be adjusted by adding the following to your `config.h`:
+
+```c
+#define IS31FL3729_PWM_FREQUENCY IS31FL3729_PWM_FREQUENCY_32K_HZ
+```
+
+Valid values are:
+
+|Define |Frequency |
+|----------------------------------|----------------|
+|`IS31FL3729_PWM_FREQUENCY_55K_HZ` |55 kHz |
+|`IS31FL3729_PWM_FREQUENCY_32K_HZ` |32 kHz (default)|
+|`IS31FL3729_PWM_FREQUENCY_4K_HZ` |4 kHz |
+|`IS31FL3729_PWM_FREQUENCY_2K_HZ` |2 kHz |
+|`IS31FL3729_PWM_FREQUENCY_1K_HZ` |1 kHz |
+|`IS31FL3729_PWM_FREQUENCY_500_HZ` |500 Hz |
+|`IS31FL3729_PWM_FREQUENCY_250_HZ` |250 Hz |
+|`IS31FL3729_PWM_FREQUENCY_80K_HZ` |80 kHz |
+
+### De-Ghosting {#de-ghosting}
+
+These settings control the pulldown and pullup resistor values on the `SWy` and `CSx` pins respectively, for the purposes of eliminating ghosting. Refer to the datasheet (p. 18) for more information on how and why this occurs.
+
+To adjust the resistor values, add the following to your `config.h`:
+
+```c
+#define IS31FL3729_SW_PULLDOWN IS31FL3729_SW_PULLDOWN_2K_OHM_SW_OFF
+#define IS31FL3729_CS_PULLUP IS31FL3729_CS_PULLUP_2K_OHM_CS_OFF
+```
+
+Valid values for `IS31FL3729_SW_PULLDOWN` are:
+
+|Define |Resistance |
+|---------------------------------------|------------------------------|
+|`IS31FL3729_SW_PULLDOWN_0_OHM` |None |
+|`IS31FL3729_SW_PULLDOWN_0K5_OHM_SW_OFF`|0.5 kΩ in SWy off time |
+|`IS31FL3729_SW_PULLDOWN_1K_OHM_SW_OFF` |1 kΩ in SWy off time |
+|`IS31FL3729_SW_PULLDOWN_2K_OHM_SW_OFF` |2 kΩ in SWy off time (default)|
+|`IS31FL3729_SW_PULLDOWN_1K_OHM` |1 kΩ |
+|`IS31FL3729_SW_PULLDOWN_2K_OHM` |2 kΩ |
+|`IS31FL3729_SW_PULLDOWN_4K_OHM` |4 kΩ |
+|`IS31FL3729_SW_PULLDOWN_8K_OHM` |8 kΩ |
+
+Valid values for `IS31FL3729_CS_PULLUP` are:
+
+|Define |Resistance |
+|-------------------------------------|------------------------------|
+|`IS31FL3729_CS_PULLUP_0_OHM` |None |
+|`IS31FL3729_CS_PULLUP_0K5_OHM_CS_OFF`|0.5 kΩ in CSx off time |
+|`IS31FL3729_CS_PULLUP_1K_OHM_CS_OFF` |1 kΩ in CSx off time |
+|`IS31FL3729_CS_PULLUP_2K_OHM_CS_OFF` |2 kΩ in CSx off time (default)|
+|`IS31FL3729_CS_PULLUP_1K_OHM` |1 kΩ |
+|`IS31FL3729_CS_PULLUP_2K_OHM` |2 kΩ |
+|`IS31FL3729_CS_PULLUP_4K_OHM` |4 kΩ |
+|`IS31FL3729_CS_PULLUP_8K_OHM` |8 kΩ |
+
+### Global Current Control {#global-current-control}
+
+This setting controls the current sunk by the `CSx` pins, from 0 to 255. By default, the value is 64, but if you need to adjust it, add the following to your `config.h`:
+
+```c
+#define IS31FL3729_GLOBAL_CURRENT 0x40
+```
+
+## ARM/ChibiOS Configuration {#arm-configuration}
+
+Depending on the ChibiOS board configuration, you may need to [enable and configure I²C](i2c#arm-configuration) at the keyboard level.
+
+## LED Mapping {#led-mapping}
+
+In order to use this driver, each output must be mapped to an LED index, by adding the following to your `<keyboardname>.c`:
+
+```c
+const is31fl3729_led_t PROGMEM g_is31fl3729_leds[IS31FL3729_LED_COUNT] = {
+/* Driver
+ * | R G B */
+ {0, SW1_CS1, SW1_CS2, SW1_CS3},
+ // etc...
+};
+```
+
+In this example, the red, green and blue channels for the first LED index on driver 0 all have their anodes connected to the `SW1` pin, and their cathodes on the `CS1`, `CS2` and `CS3` pins respectively.
+
+For the single-color driver, the principle is the same, but there is only one channel:
+
+```c
+const is31fl3729_led_t PROGMEM g_is31fl3729_leds[IS31FL3729_LED_COUNT] = {
+/* Driver
+ * | V */
+ {0, SW1_CS1},
+ // etc...
+};
+```
+
+These values correspond to the register indices as shown in the datasheet on page 12, figure 9.

+I2C_DRIVER_REQUIRED = yes
+```
+
+## Basic Configuration {#basic-configuration}
+
+Add the following to your `config.h`:
+
+|Define |Default |Description |
+|----------------------------|-------------|----------------------------------------------------|
+|`IS31FL3731_SDB_PIN` |*Not defined*|The GPIO pin connected to the drivers' shutdown pins|

+# IS31FL3733 Driver {#is31fl3733-driver}
+
+I²C 12x16 LED matrix driver by Lumissil. Supports a maximum of four drivers, each controlling up to 192 single-color LEDs, or 64 RGB LEDs.
+
+[IS31FL3733 Datasheet](https://www.lumissil.com/assets/pdf/core/IS31FL3733_DS.pdf)
+
+## Usage {#usage}
+
+The IS31FL3733 driver code is automatically included if you are using the [LED Matrix](../features/led_matrix) or [RGB Matrix](../features/rgb_matrix) feature with the `is31fl3733` driver set, and you would use those APIs instead.
+
+However, if you need to use the driver standalone, add this to your `rules.mk`:
+
+```make
+COMMON_VPATH += $(DRIVER_PATH)/led/issi
+SRC += is31fl3733-mono.c # For single-color
+SRC += is31fl3733.c # For RGB
+I2C_DRIVER_REQUIRED = yes
+```
+
+## Basic Configuration {#basic-configuration}
+
+Add the following to your `config.h`:
+
+|Define |Default |Description |
+|----------------------------|---------------------------------|----------------------------------------------------|
+|`IS31FL3733_SDB_PIN` |*Not defined* |The GPIO pin connected to the drivers' shutdown pins|

+|`IS31FL3733_CS_PULLDOWN` |`IS31FL3733_PDR_0_OHM` |The `CSx` pulldown resistor value |
+|`IS31FL3733_GLOBAL_CURRENT` |`0xFF` |The global current control value |
+
+### I²C Addressing {#i2c-addressing}
+
+The IS31FL3733 has 16 possible 7-bit I²C addresses, depending on how the `ADDR1` and `ADDR2` pins are connected.
+
+To configure this, set the `IS31FL3733_I2C_ADDRESS_n` defines to one of the following in your `config.h`, where *n* denotes the driver index:
+
+|Define |Value |
+|--------------------------------|------|
+|`IS31FL3733_I2C_ADDRESS_GND_GND`|`0x50`|
+|`IS31FL3733_I2C_ADDRESS_GND_SCL`|`0x51`|
+|`IS31FL3733_I2C_ADDRESS_GND_SDA`|`0x52`|
+|`IS31FL3733_I2C_ADDRESS_GND_VCC`|`0x53`|
+|`IS31FL3733_I2C_ADDRESS_SCL_GND`|`0x54`|
+|`IS31FL3733_I2C_ADDRESS_SCL_SCL`|`0x55`|
+|`IS31FL3733_I2C_ADDRESS_SCL_SDA`|`0x56`|
+|`IS31FL3733_I2C_ADDRESS_SCL_VCC`|`0x57`|
+|`IS31FL3733_I2C_ADDRESS_SDA_GND`|`0x58`|

+|`IS31FL3733_I2C_ADDRESS_VCC_GND`|`0x5C`|
+|`IS31FL3733_I2C_ADDRESS_VCC_SCL`|`0x5D`|
+|`IS31FL3733_I2C_ADDRESS_VCC_SDA`|`0x5E`|
+|`IS31FL3733_I2C_ADDRESS_VCC_VCC`|`0x5F`|
+
+### Multi-Driver Synchronization {#multi-driver-synchronization}
+
+Multiple IS31FL3733 drivers can be synchronized by connecting the `SYNC` pins together. One driver must be designated as the "master", and the others configured as "slave".
+
+To do this, set the `IS31FL3733_SYNC_n` defines accordingly in your `config.h`, where *n* denotes the driver index:
+
+|Define |Value |
+|------------------------|---------------------------|
+|`IS31FL3733_SYNC_NONE` |No synchronization |
+|`IS31FL3733_SYNC_MASTER`|Driver configured as master|
+|`IS31FL3733_SYNC_SLAVE` |Driver configured as slave |
+
+### PWM Frequency {#pwm-frequency}
+
+The PWM frequency can be adjusted (for IS31FL3733B only) by adding the following to your `config.h`:
+
+```c
+#define IS31FL3733_PWM_FREQUENCY IS31FL3733_PWM_FREQUENCY_8K4_HZ
+```
+
+Valid values are:
+
+|Define |Frequency |
+|----------------------------------|-----------------|
+|`IS31FL3733_PWM_FREQUENCY_8K4_HZ` |8.4 kHz (default)|
+|`IS31FL3733_PWM_FREQUENCY_4K2_HZ` |4.2 kHz |
+|`IS31FL3733_PWM_FREQUENCY_26K7_HZ`|26.7 kHz |
+|`IS31FL3733_PWM_FREQUENCY_2K1_HZ` |2.1 kHz |
+|`IS31FL3733_PWM_FREQUENCY_1K05_HZ`|1.05 kHz |
+
+### De-Ghosting {#de-ghosting}
+
+These settings control the pullup and pulldown resistor values on the `SWy` and `CSx` pins respectively, for the purposes of eliminating ghosting. Refer to the datasheet (p. 23) for more information on how and why this occurs.
+
+To adjust the resistor values, add the following to your `config.h`:
+
+```c
+#define IS31FL3733_SW_PULLUP IS31FL3733_PUR_0_OHM
+#define IS31FL3733_CS_PULLDOWN IS31FL3733_PUR_0_OHM
+```
+
+Valid values for `IS31FL3733_SW_PULLUP` are:
+
+|Define |Resistance |
+|------------------------|--------------|
+|`IS31FL3733_PUR_0_OHM` |None (default)|
+|`IS31FL3733_PUR_0K5_OHM`|0.5 kΩ |
+|`IS31FL3733_PUR_1K_OHM` |1 kΩ |
+|`IS31FL3733_PUR_2K_OHM` |2 kΩ |
+|`IS31FL3733_PUR_4K_OHM` |4 kΩ |
+|`IS31FL3733_PUR_8K_OHM` |8 kΩ |
+|`IS31FL3733_PUR_16K_OHM`|16 kΩ |
+|`IS31FL3733_PUR_32K_OHM`|32 kΩ |
+
+Valid values for `IS31FL3733_CS_PULLDOWN` are:
+
+|Define |Resistance |
+|------------------------|--------------|
+|`IS31FL3733_PDR_0_OHM` |None (default)|
+|`IS31FL3733_PDR_0K5_OHM`|0.5 kΩ |
+|`IS31FL3733_PDR_1K_OHM` |1 kΩ |
+|`IS31FL3733_PDR_2K_OHM` |2 kΩ |
+|`IS31FL3733_PDR_4K_OHM` |4 kΩ |
+|`IS31FL3733_PDR_8K_OHM` |8 kΩ |
+|`IS31FL3733_PDR_16K_OHM`|16 kΩ |
+|`IS31FL3733_PDR_32K_OHM`|32 kΩ |
+
+### Global Current Control {#global-current-control}
+
+This setting controls the current sunk by the `CSx` pins, from 0 to 255. By default, the value is the maximum (255), but if you need to lower it, add the following to your `config.h`:
+
+```c
+#define IS31FL3733_GLOBAL_CURRENT 0xFF
+```
+
+## ARM/ChibiOS Configuration {#arm-configuration}
+
+Depending on the ChibiOS board configuration, you may need to [enable and configure I²C](i2c#arm-configuration) at the keyboard level.
+
+## LED Mapping {#led-mapping}
+
+In order to use this driver, each output must be mapped to an LED index, by adding the following to your `<keyboardname>.c`:
+
+```c
+const is31fl3733_led_t PROGMEM g_is31fl3733_leds[IS31FL3733_LED_COUNT] = {
+/* Driver
+ * | R G B */
+ {0, SW1_CS1, SW1_CS2, SW1_CS3},
+ // etc...
+};
+```
+
+In this example, the red, green and blue channels for the first LED index on driver 0 all have their cathodes connected to the `SW1` pin, and their anodes on the `CS1`, `CS2` and `CS3` pins respectively.
+
+For the single-color driver, the principle is the same, but there is only one channel:
+
+```c
+const is31fl3733_led_t PROGMEM g_is31fl3733_leds[IS31FL3733_LED_COUNT] = {
+/* Driver
+ * | V */
+ {0, SW1_CS1},
+ // etc...
+};
+```
+
+These values correspond to the register indices as shown in the datasheet on page 15, figure 9.

+These settings control the pullup and pulldown resistor values on the `SWy` and `CSx` pins respectively, for the purposes of eliminating ghosting. Refer to the datasheet (p. 25) for more information on how and why this occurs.
+
+To adjust the resistor values, add the following to your `config.h`:
+
+```c
+#define IS31FL3736_SW_PULLUP IS31FL3736_PUR_0_OHM
+#define IS31FL3736_CS_PULLDOWN IS31FL3736_PDR_0_OHM
+```
+
+Valid values for `IS31FL3736_SW_PULLUP` are:
+
+|Define |Resistance |
+|------------------------|--------------|
+|`IS31FL3736_PUR_0_OHM` |None (default)|
+|`IS31FL3736_PUR_0K5_OHM`|0.5 kΩ |
+|`IS31FL3736_PUR_1K_OHM` |1 kΩ |
+|`IS31FL3736_PUR_2K_OHM` |2 kΩ |
+|`IS31FL3736_PUR_4K_OHM` |4 kΩ |
+|`IS31FL3736_PUR_8K_OHM` |8 kΩ |
+|`IS31FL3736_PUR_16K_OHM`|16 kΩ |
+|`IS31FL3736_PUR_32K_OHM`|32 kΩ |
+
+Valid values for `IS31FL3736_CS_PULLDOWN` are:
+
+|Define |Resistance |
+|------------------------|--------------|
+|`IS31FL3736_PDR_0_OHM` |None (default)|
+|`IS31FL3736_PDR_0K5_OHM`|0.5 kΩ |
+|`IS31FL3736_PDR_1K_OHM` |1 kΩ |
+|`IS31FL3736_PDR_2K_OHM` |2 kΩ |
+|`IS31FL3736_PDR_4K_OHM` |4 kΩ |
+|`IS31FL3736_PDR_8K_OHM` |8 kΩ |
+|`IS31FL3736_PDR_16K_OHM`|16 kΩ |
+|`IS31FL3736_PDR_32K_OHM`|32 kΩ |
+
+### Global Current Control {#global-current-control}
+
+This setting controls the current sunk by the `CSx` pins, from 0 to 255. By default, the value is the maximum (255), but if you need to lower it, add the following to your `config.h`:
+
+```c
+#define IS31FL3736_GLOBAL_CURRENT 0xFF
+```
+
+## ARM/ChibiOS Configuration {#arm-configuration}
+
+Depending on the ChibiOS board configuration, you may need to [enable and configure I²C](i2c#arm-configuration) at the keyboard level.
+
+## LED Mapping {#led-mapping}
+
+In order to use this driver, each output must be mapped to an LED index, by adding the following to your `<keyboardname>.c`:
+
+```c
+const is31fl3736_led_t PROGMEM g_is31fl3736_leds[IS31FL3736_LED_COUNT] = {
+/* Driver
+ * | R G B */
+ {0, SW1_CS1, SW1_CS2, SW1_CS3},
+ // etc...
+};
+```
+
+In this example, the red, green and blue channels for the first LED index on driver 0 all have their cathodes connected to the `SW1` pin, and their anodes on the `CS1`, `CS2` and `CS3` pins respectively.
+
+For the single-color driver, the principle is the same, but there is only one channel:
+
+```c
+const is31fl3736_led_t PROGMEM g_is31fl3736_leds[IS31FL3736_LED_COUNT] = {
+/* Driver
+ * | V */
+ {0, SW1_CS1},
+ // etc...
+};
+```
+
+These values correspond to the register indices as shown in the datasheet on page 16, figure 9.

+# IS31FL3737 Driver {#is31fl3737-driver}
+
+I²C 12x12 LED matrix driver by Lumissil. Supports a maximum of four drivers, each controlling up to 144 single-color LEDs, or 48 RGB LEDs.
+
+[IS31FL3737 Datasheet](https://www.lumissil.com/assets/pdf/core/IS31FL3737_DS.pdf)
+
+## Usage {#usage}
+
+The IS31FL3737 driver code is automatically included if you are using the [LED Matrix](../features/led_matrix) or [RGB Matrix](../features/rgb_matrix) feature with the `is31fl3737` driver set, and you would use those APIs instead.
+
+However, if you need to use the driver standalone, add this to your `rules.mk`:
+
+```make
+COMMON_VPATH += $(DRIVER_PATH)/led/issi
+SRC += is31fl3737-mono.c # For single-color
+SRC += is31fl3737.c # For RGB
+I2C_DRIVER_REQUIRED = yes
+```
+
+## Basic Configuration {#basic-configuration}
+
+Add the following to your `config.h`:
+
+|Define |Default |Description |
+|----------------------------|---------------------------------|----------------------------------------------------|
+|`IS31FL3737_SDB_PIN` |*Not defined* |The GPIO pin connected to the drivers' shutdown pins|
+|`IS31FL3737_I2C_TIMEOUT` |`100` |The I²C timeout in milliseconds |
+|`IS31FL3737_I2C_PERSISTENCE`|`0` |The number of times to retry I²C transmissions |

+|`IS31FL3737_PWM_FREQUENCY` |`IS31FL3737_PWM_FREQUENCY_8K4_HZ`|The PWM frequency of the LEDs (IS31FL3737B only) |
+|`IS31FL3737_SW_PULLUP` |`IS31FL3737_PUR_0_OHM` |The `SWx` pullup resistor value |
+|`IS31FL3737_CS_PULLDOWN` |`IS31FL3737_PDR_0_OHM` |The `CSx` pulldown resistor value |
+|`IS31FL3737_GLOBAL_CURRENT` |`0xFF` |The global current control value |
+
+### I²C Addressing {#i2c-addressing}
+
+The IS31FL3737 has four possible 7-bit I²C addresses, depending on how the `ADDR` pin is connected.
+
+To configure this, set the `IS31FL3737_I2C_ADDRESS_n` defines to one of the following in your `config.h`, where *n* denotes the driver index:
+
+|Define |Value |
+|----------------------------|------|
+|`IS31FL3737_I2C_ADDRESS_GND`|`0x50`|
+|`IS31FL3737_I2C_ADDRESS_SCL`|`0x55`|
+|`IS31FL3737_I2C_ADDRESS_SDA`|`0x5A`|
+|`IS31FL3737_I2C_ADDRESS_VCC`|`0x5F`|
+
+### PWM Frequency {#pwm-frequency}
+
+The PWM frequency can be adjusted (for IS31FL3737B only) by adding the following to your `config.h`:
+
+```c
+#define IS31FL3737_PWM_FREQUENCY IS31FL3737_PWM_FREQUENCY_8K4_HZ
+```
+
+Valid values are:
+
+|Define |Frequency |
+|----------------------------------|-----------------|
+|`IS31FL3737_PWM_FREQUENCY_8K4_HZ` |8.4 kHz (default)|
+|`IS31FL3737_PWM_FREQUENCY_4K2_HZ` |4.2 kHz |

+|`IS31FL3737_PWM_FREQUENCY_2K1_HZ` |2.1 kHz |
+|`IS31FL3737_PWM_FREQUENCY_1K05_HZ`|1.05 kHz |
+
+### De-Ghosting {#de-ghosting}
+
+These settings control the pullup and pulldown resistor values on the `SWy` and `CSx` pins respectively, for the purposes of eliminating ghosting. Refer to the datasheet (p. 23) for more information on how and why this occurs.
+
+To adjust the resistor values, add the following to your `config.h`:
+
+```c
+#define IS31FL3737_SW_PULLUP IS31FL3737_PUR_0_OHM
+#define IS31FL3737_CS_PULLDOWN IS31FL3737_PDR_0_OHM
+```
+
+Valid values for `IS31FL3737_SW_PULLUP` are:
+
+|Define |Resistance |
+|------------------------|--------------|
+|`IS31FL3737_PUR_0_OHM` |None (default)|
+|`IS31FL3737_PUR_0K5_OHM`|0.5 kΩ |

+|`IS31FL3737_PUR_16K_OHM`|16 kΩ |
+|`IS31FL3737_PUR_32K_OHM`|32 kΩ |
+
+Valid values for `IS31FL3737_CS_PULLDOWN` are:
+
+|Define |Resistance |
+|------------------------|--------------|
+|`IS31FL3737_PDR_0_OHM` |None (default)|
+|`IS31FL3737_PDR_0K5_OHM`|0.5 kΩ |
+|`IS31FL3737_PDR_1K_OHM` |1 kΩ |

+|`IS31FL3737_PDR_16K_OHM`|16 kΩ |
+|`IS31FL3737_PDR_32K_OHM`|32 kΩ |
+
+### Global Current Control {#global-current-control}
+
+This setting controls the current sunk by the `CSx` pins, from 0 to 255. By default, the value is the maximum (255), but if you need to lower it, add the following to your `config.h`:
+
+```c
+#define IS31FL3737_GLOBAL_CURRENT 0xFF
+```
+
+## ARM/ChibiOS Configuration {#arm-configuration}
+
+Depending on the ChibiOS board configuration, you may need to [enable and configure I²C](i2c#arm-configuration) at the keyboard level.
+
+## LED Mapping {#led-mapping}
+
+In order to use this driver, each output must be mapped to an LED index, by adding the following to your `<keyboardname>.c`:
+
+```c
+const is31fl3737_led_t PROGMEM g_is31fl3737_leds[IS31FL3737_LED_COUNT] = {
+/* Driver
+ * | R G B */
+ {0, SW1_CS1, SW1_CS2, SW1_CS3},
+ // etc...
+};
+```
+
+In this example, the red, green and blue channels for the first LED index on driver 0 all have their cathodes connected to the `SW1` pin, and their anodes on the `CS1`, `CS2` and `CS3` pins respectively.
+
+For the single-color driver, the principle is the same, but there is only one channel:
+
+```c
+const is31fl3737_led_t PROGMEM g_is31fl3737_leds[IS31FL3737_LED_COUNT] = {
+/* Driver
+ * | V */
+ {0, SW1_CS1},
+ // etc...
+};
+```
+
+These values correspond to the register indices as shown in the datasheet on page 15, figure 9.

+# IS31FL3741 Driver {#is31fl3741-driver}
+
+I²C 39x9 LED matrix driver by Lumissil. Supports a maximum of four drivers, each controlling up to 351 single-color LEDs, or 117 RGB LEDs.
+
+[IS31FL3741A Datasheet](https://www.lumissil.com/assets/pdf/core/IS31FL3741A_DS.pdf)
+
+## Usage {#usage}
+
+The IS31FL3741 driver code is automatically included if you are using the [LED Matrix](../features/led_matrix) or [RGB Matrix](../features/rgb_matrix) feature with the `is31fl3741` driver set, and you would use those APIs instead.
+
+However, if you need to use the driver standalone, add this to your `rules.mk`:
+
+```make
+COMMON_VPATH += $(DRIVER_PATH)/led/issi
+SRC += is31fl3741-mono.c # For single-color
+SRC += is31fl3741.c # For RGB
+I2C_DRIVER_REQUIRED = yes
+```
+
+## Basic Configuration {#basic-configuration}
+
+Add the following to your `config.h`:
+
+|Define |Default |Description |
+|----------------------------|---------------------------------|----------------------------------------------------|
+|`IS31FL3741_SDB_PIN` |*Not defined* |The GPIO pin connected to the drivers' shutdown pins|
+|`IS31FL3741_I2C_TIMEOUT` |`100` |The I²C timeout in milliseconds |
+|`IS31FL3741_I2C_PERSISTENCE`|`0` |The number of times to retry I²C transmissions |
+|`IS31FL3741_I2C_ADDRESS_1` |*Not defined* |The I²C address of driver 0 |
+|`IS31FL3741_I2C_ADDRESS_2` |*Not defined* |The I²C address of driver 1 |
+|`IS31FL3741_I2C_ADDRESS_3` |*Not defined* |The I²C address of driver 2 |
+|`IS31FL3741_I2C_ADDRESS_4` |*Not defined* |The I²C address of driver 3 |
+|`IS31FL3741_CONFIGURATION` |`1` |The value of the configuration register |
+|`IS31FL3741_PWM_FREQUENCY` |`IS31FL3741_PWM_FREQUENCY_29K_HZ`|The PWM frequency of the LEDs (IS31FL3741A only) |
+|`IS31FL3741_SW_PULLUP` |`IS31FL3741_PUR_32K_OHM` |The `SWx` pullup resistor value |
+|`IS31FL3741_CS_PULLDOWN` |`IS31FL3741_PDR_32K_OHM` |The `CSx` pulldown resistor value |
+|`IS31FL3741_GLOBAL_CURRENT` |`0xFF` |The global current control value |
+
+### I²C Addressing {#i2c-addressing}
+
+The IS31FL3741 has four possible 7-bit I²C addresses, depending on how the `ADDR` pin is connected.
+
+To configure this, set the `IS31FL3741_I2C_ADDRESS_n` defines to one of the following in your `config.h`, where *n* denotes the driver index:
+
+|Define |Value |
+|----------------------------|------|
+|`IS31FL3741_I2C_ADDRESS_GND`|`0x30`|
+|`IS31FL3741_I2C_ADDRESS_SCL`|`0x31`|
+|`IS31FL3741_I2C_ADDRESS_SDA`|`0x32`|
+|`IS31FL3741_I2C_ADDRESS_VCC`|`0x33`|
+
+### PWM Frequency {#pwm-frequency}
+
+The PWM frequency can be adjusted (for IS31FL3741A only) by adding the following to your `config.h`:
+
+```c
+#define IS31FL3741_PWM_FREQUENCY IS31FL3741_PWM_FREQUENCY_29K_HZ
+```
+
+Valid values are:
+
+|Define |Frequency |
+|---------------------------------|----------------|
+|`IS31FL3741_PWM_FREQUENCY_29K_HZ`|29 kHz (default)|
+|`IS31FL3741_PWM_FREQUENCY_3K6_HZ`|3.6 kHz |
+|`IS31FL3741_PWM_FREQUENCY_1K8_HZ`|1.8 kHz |
+|`IS31FL3741_PWM_FREQUENCY_900_HZ`|900 Hz |
+
+### De-Ghosting {#de-ghosting}
+
+These settings control the pullup and pulldown resistor values on the `CSx` and `SWy` pins respectively, for the purposes of eliminating ghosting. Refer to the datasheet (p. 18) for more information on how and why this occurs.
+
+To adjust the resistor values, add the following to your `config.h`:
+
+```c
+#define IS31FL3741_SW_PULLUP IS31FL3741_PUR_32K_OHM
+#define IS31FL3741_CS_PULLDOWN IS31FL3741_PDR_32K_OHM
+```
+
+Valid values for `IS31FL3741_SW_PULLUP` are:
+
+|Define |Resistance |
+|------------------------|---------------|
+|`IS31FL3741_PUR_0_OHM` |None |
+|`IS31FL3741_PUR_0K5_OHM`|0.5 kΩ |
+|`IS31FL3741_PUR_1K_OHM` |1 kΩ |
+|`IS31FL3741_PUR_2K_OHM` |2 kΩ |
+|`IS31FL3741_PUR_4K_OHM` |4 kΩ |
+|`IS31FL3741_PUR_8K_OHM` |8 kΩ |
+|`IS31FL3741_PUR_16K_OHM`|16 kΩ |
+|`IS31FL3741_PUR_32K_OHM`|32 kΩ (default)|
+
+Valid values for `IS31FL3741_CS_PULLDOWN` are:
+
+|Define |Resistance |
+|------------------------|---------------|
+|`IS31FL3741_PDR_0_OHM` |None |
+|`IS31FL3741_PDR_0K5_OHM`|0.5 kΩ |
+|`IS31FL3741_PDR_1K_OHM` |1 kΩ |
+|`IS31FL3741_PDR_2K_OHM` |2 kΩ |
+|`IS31FL3741_PDR_4K_OHM` |4 kΩ |
+|`IS31FL3741_PDR_8K_OHM` |8 kΩ |
+|`IS31FL3741_PDR_16K_OHM`|16 kΩ |
+|`IS31FL3741_PDR_32K_OHM`|32 kΩ (default)|
+
+### Global Current Control {#global-current-control}
+
+This setting controls the current sunk by the `CSx` pins, from 0 to 255. By default, the value is the maximum (255), but if you need to lower it, add the following to your `config.h`:
+
+```c
+#define IS31FL3741_GLOBAL_CURRENT 0xFF
+```
+
+## ARM/ChibiOS Configuration {#arm-configuration}
+
+Depending on the ChibiOS board configuration, you may need to [enable and configure I²C](i2c#arm-configuration) at the keyboard level.
+
+## LED Mapping {#led-mapping}
+
+In order to use this driver, each output must be mapped to an LED index, by adding the following to your `<keyboardname>.c`:
+
+```c
+const is31fl3741_led_t PROGMEM g_is31fl3741_leds[IS31FL3741_LED_COUNT] = {
+/* Driver
+ * | R G B */
+ {0, SW1_CS1, SW1_CS2, SW1_CS3},
+ // etc...
+};
+```
+
+In this example, the red, green and blue channels for the first LED index on driver 0 all have their anodes connected to the `SW1` pin, and their cathodes on the `CS1`, `CS2` and `CS3` pins respectively.
+
+For the single-color driver, the principle is the same, but there is only one channel:
+
+```c
+const is31fl3741_led_t PROGMEM g_is31fl3741_leds[IS31FL3741_LED_COUNT] = {
+/* Driver
+ * | V */
+ {0, SW1_CS1},
+ // etc...
+};
+```
+
+These values correspond to the register indices as shown in the datasheet on page 12, figure 8.

+# IS31FL3743A Driver {#is31fl3743a-driver}
+
+I²C 18x11 LED matrix driver by Lumissil. Supports a maximum of four drivers, each controlling up to 198 single-color LEDs, or 66 RGB LEDs.
+
+[IS31FL3743A Datasheet](https://www.lumissil.com/assets/pdf/core/IS31FL3743A_DS.pdf)
+
+## Usage {#usage}
+
+The IS31FL3743A driver code is automatically included if you are using the [LED Matrix](../features/led_matrix) or [RGB Matrix](../features/rgb_matrix) feature with the `is31fl3743a` driver set, and you would use those APIs instead.
+
+However, if you need to use the driver standalone, add this to your `rules.mk`:
+
+```make
+COMMON_VPATH += $(DRIVER_PATH)/led/issi
+SRC += is31fl3743a-mono.c # For single-color
+SRC += is31fl3743a.c # For RGB
+I2C_DRIVER_REQUIRED = yes
+```
+
+## Basic Configuration {#basic-configuration}
+
+Add the following to your `config.h`:
+
+|Define |Default |Description |
+|-----------------------------|-------------------------------|----------------------------------------------------|
+|`IS31FL3743A_SDB_PIN` |*Not defined* |The GPIO pin connected to the drivers' shutdown pins|

+|`IS31FL3743A_SYNC_3` |`IS31FL3743A_SYNC_NONE` |The sync configuration for driver 2 |
+|`IS31FL3743A_SYNC_4` |`IS31FL3743A_SYNC_NONE` |The sync configuration for driver 3 |
+|`IS31FL3743A_CONFIGURATION` |`0x01` |The value of the configuration register |
+|`IS31FL3743A_SW_PULLDOWN` |`IS31FL3743A_PDR_2K_OHM_SW_OFF`|The `SWx` pulldown resistor value |
+|`IS31FL3743A_CS_PULLUP` |`IS31FL3743A_PUR_2K_OHM_CS_OFF`|The `CSx` pullup resistor value |
+|`IS31FL3743A_GLOBAL_CURRENT` |`0xFF` |The global current control value |
+
+### I²C Addressing {#i2c-addressing}
+
+The IS31FL3743A has 16 possible 7-bit I²C addresses, depending on how the `ADDR1` and `ADDR2` pins are connected.
+
+To configure this, set the `IS31FL3743A_I2C_ADDRESS_n` defines to one of the following in your `config.h`, where *n* denotes the driver index:
+
+|Define |Value |
+|---------------------------------|------|
+|`IS31FL3743A_I2C_ADDRESS_GND_GND`|`0x20`|
+|`IS31FL3743A_I2C_ADDRESS_GND_SCL`|`0x21`|
+|`IS31FL3743A_I2C_ADDRESS_GND_SDA`|`0x22`|
+|`IS31FL3743A_I2C_ADDRESS_GND_VCC`|`0x23`|
+|`IS31FL3743A_I2C_ADDRESS_SCL_GND`|`0x24`|
+|`IS31FL3743A_I2C_ADDRESS_SCL_SCL`|`0x25`|
+|`IS31FL3743A_I2C_ADDRESS_SCL_SDA`|`0x26`|

+|`IS31FL3743A_I2C_ADDRESS_SDA_SDA`|`0x2A`|
+|`IS31FL3743A_I2C_ADDRESS_SDA_VCC`|`0x2B`|
+|`IS31FL3743A_I2C_ADDRESS_VCC_GND`|`0x2C`|
+|`IS31FL3743A_I2C_ADDRESS_VCC_SCL`|`0x2D`|
+|`IS31FL3743A_I2C_ADDRESS_VCC_SDA`|`0x2E`|
+|`IS31FL3743A_I2C_ADDRESS_VCC_VCC`|`0x2F`|
+
+### Multi-Driver Synchronization {#multi-driver-synchronization}
+
+Multiple IS31FL3743A drivers can be synchronized by connecting the `SYNC` pins together. One driver must be designated as the "master", and the others configured as "slave".
+
+To do this, set the `IS31FL3743A_SYNC_n` defines accordingly in your `config.h`, where *n* denotes the driver index:
+
+|Define |Value |
+|-------------------------|---------------------------|
+|`IS31FL3743A_SYNC_NONE` |No synchronization |
+|`IS31FL3743A_SYNC_MASTER`|Driver configured as master|
+|`IS31FL3743A_SYNC_SLAVE` |Driver configured as slave |
+
+### De-Ghosting {#de-ghosting}
+
+These settings control the pulldown and pullup resistor values on the `SWy` and `CSx` pins respectively, for the purposes of eliminating ghosting. Refer to the datasheet (p. 23) for more information on how and why this occurs.
+
+To adjust the resistor values, add the following to your `config.h`:
+
+```c
+#define IS31FL3743A_SW_PULLDOWN IS31FL3743A_PDR_2K_OHM_SW_OFF
+#define IS31FL3743A_CS_PULLUP IS31FL3743A_PUR_2K_OHM_CS_OFF
+```
+
+Valid values for `IS31FL3743A_SW_PULLDOWN` are:
+
+|Define |Resistance |
+|--------------------------------|------------------------------|
+|`IS31FL3743A_PDR_0_OHM` |None (default) |
+|`IS31FL3743A_PDR_0K5_OHM_SW_OFF`|0.5 kΩ in SWx off time |
+|`IS31FL3743A_PDR_1K_OHM_SW_OFF` |1 kΩ in SWx off time |
+|`IS31FL3743A_PDR_2K_OHM_SW_OFF` |2 kΩ in SWx off time (default)|
+|`IS31FL3743A_PDR_1K_OHM` |1 kΩ |
+|`IS31FL3743A_PDR_2K_OHM` |2 kΩ |
+|`IS31FL3743A_PDR_4K_OHM` |4 kΩ |
+|`IS31FL3743A_PDR_8K_OHM` |8 kΩ |
+
+Valid values for `IS31FL3743A_CS_PULLUP` are:
+
+|Define |Resistance |
+|--------------------------------|------------------------------|
+|`IS31FL3743A_PUR_0_OHM` |None (default) |
+|`IS31FL3743A_PUR_0K5_OHM_CS_OFF`|0.5 kΩ in CSy off time |
+|`IS31FL3743A_PUR_1K_OHM_CS_OFF` |1 kΩ in CSy off time |
+|`IS31FL3743A_PUR_2K_OHM_CS_OFF` |2 kΩ in CSy off time (default)|
+|`IS31FL3743A_PUR_1K_OHM` |1 kΩ |
+|`IS31FL3743A_PUR_2K_OHM` |2 kΩ |
+|`IS31FL3743A_PUR_4K_OHM` |4 kΩ |
+|`IS31FL3743A_PUR_8K_OHM` |8 kΩ |
+
+### Global Current Control {#global-current-control}
+
+This setting controls the current sunk by the `CSy` pins, from 0 to 255. By default, the value is the maximum (255), but if you need to lower it, add the following to your `config.h`:
+
+```c
+#define IS31FL3743A_GLOBAL_CURRENT 0xFF
+```
+
+## ARM/ChibiOS Configuration {#arm-configuration}
+
+Depending on the ChibiOS board configuration, you may need to [enable and configure I²C](i2c#arm-configuration) at the keyboard level.
+
+## LED Mapping {#led-mapping}
+
+In order to use this driver, each output must be mapped to an LED index, by adding the following to your `<keyboardname>.c`:
+
+```c
+const is31fl3743a_led_t PROGMEM g_is31fl3743a_leds[IS31FL3743A_LED_COUNT] = {
+/* Driver
+ * | R G B */
+ {0, SW1_CS1, SW1_CS2, SW1_CS3},
+ // etc...
+};
+```
+
+In this example, the red, green and blue channels for the first LED index on driver 0 all have their anodes connected to the `SW1` pin, and their cathodes on the `CS1`, `CS2` and `CS3` pins respectively.
+
+For the single-color driver, the principle is the same, but there is only one channel:
+
+```c
+const is31fl3743a_led_t PROGMEM g_is31fl3743a_leds[IS31FL3743A_LED_COUNT] = {
+/* Driver
+ * | V */
+ {0, SW1_CS1},
+ // etc...
+};
+```
+
+These values correspond to the register indices as shown in the datasheet on page 12, figure 8.

+To configure this, set the `IS31FL3745_I2C_ADDRESS_n` defines to one of the following in your `config.h`, where *n* denotes the driver index:
+
+|Define |Value |
+|--------------------------------|------|
+|`IS31FL3745_I2C_ADDRESS_GND_GND`|`0x20`|
+|`IS31FL3745_I2C_ADDRESS_GND_SCL`|`0x21`|
+|`IS31FL3745_I2C_ADDRESS_GND_SDA`|`0x22`|
+|`IS31FL3745_I2C_ADDRESS_GND_VCC`|`0x23`|
+|`IS31FL3745_I2C_ADDRESS_SCL_GND`|`0x24`|
+|`IS31FL3745_I2C_ADDRESS_SCL_SCL`|`0x25`|
+|`IS31FL3745_I2C_ADDRESS_SCL_SDA`|`0x26`|
+|`IS31FL3745_I2C_ADDRESS_SCL_VCC`|`0x27`|

+|`IS31FL3745_I2C_ADDRESS_VCC_SDA`|`0x2E`|
+|`IS31FL3745_I2C_ADDRESS_VCC_VCC`|`0x2F`|
+
+### Multi-Driver Synchronization {#multi-driver-synchronization}
+
+Multiple IS31FL3745 drivers can be synchronized by connecting the `SYNC` pins together. One driver must be designated as the "master", and the others configured as "slave".
+
+To do this, set the `IS31FL3745_SYNC_n` defines accordingly in your `config.h`, where *n* denotes the driver index:
+
+|Define |Value |
+|------------------------|---------------------------|
+|`IS31FL3745_SYNC_NONE` |No synchronization |
+|`IS31FL3745_SYNC_MASTER`|Driver configured as master|
+|`IS31FL3745_SYNC_SLAVE` |Driver configured as slave |
+
+### De-Ghosting {#de-ghosting}
+
+These settings control the pulldown and pullup resistor values on the `SWy` and `CSx` pins respectively, for the purposes of eliminating ghosting. Refer to the datasheet (p. 23) for more information on how and why this occurs.
+
+To adjust the resistor values, add the following to your `config.h`:
+
+```c
+#define IS31FL3745_SW_PULLDOWN IS31FL3745_PDR_2K_OHM_SW_OFF
+#define IS31FL3745_CS_PULLUP IS31FL3745_PUR_2K_OHM_CS_OFF
+```
+
+Valid values for `IS31FL3745_SW_PULLDOWN` are:
+
+|Define |Resistance |
+|-------------------------------|------------------------------|
+|`IS31FL3745_PDR_0_OHM` |None (default) |
+|`IS31FL3745_PDR_0K5_OHM_SW_OFF`|0.5 kΩ in SWx off time |
+|`IS31FL3745_PDR_1K_OHM_SW_OFF` |1 kΩ in SWx off time |
+|`IS31FL3745_PDR_2K_OHM_SW_OFF` |2 kΩ in SWx off time (default)|
+|`IS31FL3745_PDR_1K_OHM` |1 kΩ |
+|`IS31FL3745_PDR_2K_OHM` |2 kΩ |
+|`IS31FL3745_PDR_4K_OHM` |4 kΩ |
+|`IS31FL3745_PDR_8K_OHM` |8 kΩ |
+
+Valid values for `IS31FL3745_CS_PULLUP` are:
+
+|Define |Resistance |
+|-------------------------------|------------------------------|
+|`IS31FL3745_PUR_0_OHM` |None (default) |
+|`IS31FL3745_PUR_0K5_OHM_CS_OFF`|0.5 kΩ in CSy off time |
+|`IS31FL3745_PUR_1K_OHM_CS_OFF` |1 kΩ in CSy off time |
+|`IS31FL3745_PUR_2K_OHM_CS_OFF` |2 kΩ in CSy off time (default)|
+|`IS31FL3745_PUR_1K_OHM` |1 kΩ |
+|`IS31FL3745_PUR_2K_OHM` |2 kΩ |
+|`IS31FL3745_PUR_4K_OHM` |4 kΩ |
+|`IS31FL3745_PUR_8K_OHM` |8 kΩ |
+
+### Global Current Control {#global-current-control}
+
+This setting controls the current sunk by the `CSy` pins, from 0 to 255. By default, the value is the maximum (255), but if you need to lower it, add the following to your `config.h`:
+
+```c
+#define IS31FL3745_GLOBAL_CURRENT 0xFF
+```
+
+## ARM/ChibiOS Configuration {#arm-configuration}
+
+Depending on the ChibiOS board configuration, you may need to [enable and configure I²C](i2c#arm-configuration) at the keyboard level.
+
+## LED Mapping {#led-mapping}
+
+In order to use this driver, each output must be mapped to an LED index, by adding the following to your `<keyboardname>.c`:
+
+```c
+const is31fl3745_led_t PROGMEM g_is31fl3745_leds[IS31FL3745_LED_COUNT] = {
+/* Driver
+ * | R G B */
+ {0, SW1_CS1, SW1_CS2, SW1_CS3},
+ // etc...
+};
+```
+
+In this example, the red, green and blue channels for the first LED index on driver 0 all have their anodes connected to the `SW1` pin, and their cathodes on the `CS1`, `CS2` and `CS3` pins respectively.
+
+For the single-color driver, the principle is the same, but there is only one channel:
+
+```c
+const is31fl3745_led_t PROGMEM g_is31fl3745_leds[IS31FL3745_LED_COUNT] = {
+/* Driver
+ * | V */
+ {0, SW1_CS1},
+ // etc...
+};
+```
+
+These values correspond to the register indices as shown in the datasheet on page 12, figure 9.

+# IS31FL3746A Driver {#is31fl3746a-driver}
+
+I²C 18x4 LED matrix driver by Lumissil. Supports a maximum of four drivers, each controlling up to 72 single-color LEDs, or 24 RGB LEDs.
+
+[IS31FL3746A Datasheet](https://www.lumissil.com/assets/pdf/core/IS31FL3746A_DS.pdf)
+
+## Usage {#usage}
+
+The IS31FL3746A driver code is automatically included if you are using the [LED Matrix](../features/led_matrix) or [RGB Matrix](../features/rgb_matrix) feature with the `is31fl3746a` driver set, and you would use those APIs instead.
+
+However, if you need to use the driver standalone, add this to your `rules.mk`:
+
+```make
+COMMON_VPATH += $(DRIVER_PATH)/led/issi
+SRC += is31fl3746a-mono.c # For single-color
+SRC += is31fl3746a.c # For RGB
+I2C_DRIVER_REQUIRED = yes
+```

+# SNLED27351 Driver {#snled27351-driver}
+
+I²C 16x12 LED matrix driver by Sonix. Supports a maximum of four drivers, each controlling up to 192 single-color LEDs, or 64 RGB LEDs.
+
+A slightly modified version of this IC is also known as "CKLED2001".
+
+[SNLED27351 Datasheet](https://www.sonix.com.tw/files/1/D235860C0C037C28E050007F01001CBE)
+
+## Usage {#usage}
+
+The SNLED27351 driver code is automatically included if you are using the [LED Matrix](../features/led_matrix) or [RGB Matrix](../features/rgb_matrix) feature with the `snled27351` driver set, and you would use those APIs instead.
+
+However, if you need to use the driver standalone, add this to your `rules.mk`:
+
+```make
+COMMON_VPATH += $(DRIVER_PATH)/led
+SRC += snled27351-mono.c # For single-color
+SRC += snled27351.c # For RGB
+I2C_DRIVER_REQUIRED = yes
+```
+
+## Basic Configuration {#basic-configuration}
+
+Add the following to your `config.h`:
+
+|Define |Default |Description |
+|----------------------------|-------------|----------------------------------------------------|
+|`SNLED27351_SDB_PIN` |*Not defined*|The GPIO pin connected to the drivers' shutdown pins|
+|`SNLED27351_I2C_TIMEOUT` |`100` |The I²C timeout in milliseconds |
+|`SNLED27351_I2C_PERSISTENCE`|`0` |The number of times to retry I²C transmissions |
+|`SNLED27351_I2C_ADDRESS_1` |*Not defined*|The I²C address of driver 0 |
+|`SNLED27351_I2C_ADDRESS_2` |*Not defined*|The I²C address of driver 1 |
+|`SNLED27351_I2C_ADDRESS_3` |*Not defined*|The I²C address of driver 2 |
+|`SNLED27351_I2C_ADDRESS_4` |*Not defined*|The I²C address of driver 3 |
+
+### I²C Addressing {#i2c-addressing}
+
+The SNLED27351 has four possible 7-bit I²C addresses, depending on how the `ADDR` pin is connected.
+
+To configure this, set the `SNLED27351_I2C_ADDRESS_n` defines to one of the following in your `config.h`, where *n* denotes the driver index:
+
+|Define |Value |
+|------------------------------|------|
+|`SNLED27351_I2C_ADDRESS_GND` |`0x74`|
+|`SNLED27351_I2C_ADDRESS_SCL` |`0x75`|
+|`SNLED27351_I2C_ADDRESS_SDA` |`0x76`|
+|`SNLED27351_I2C_ADDRESS_VDDIO`|`0x77`|
+
+## ARM/ChibiOS Configuration {#arm-configuration}
+
+Depending on the ChibiOS board configuration, you may need to [enable and configure I²C](i2c#arm-configuration) at the keyboard level.
+
+## LED Mapping {#led-mapping}
+
+In order to use this driver, each output must be mapped to an LED index, by adding the following to your `<keyboardname>.c`:
+
+```c
+const snled27351_led_t PROGMEM g_snled27351_leds[SNLED27351_LED_COUNT] = {
+/* Driver
+ * | R G B */
+ {0, CB1_CA1, CB1_CA2, CB1_CA3},
+ // etc...
+};
+```
+
+In this example, the red, green and blue channels for the first LED index on driver 0 all have their cathodes connected to the `CB1` pin, and their anodes on the `CA1`, `CA2` and `CA3` pins respectively.
+
+For the single-color driver, the principle is the same, but there is only one channel:
+
+```c
+const snled27351_led_t PROGMEM g_snled27351_leds[SNLED27351_LED_COUNT] = {
+/* Driver
+ * | V */
+ {0, CB1_CA1},
+ // etc...
+};
+```
+
+These values correspond to the register indices as shown in the datasheet on page 13.
