From 39ac72f2d12a9c62b2e876de4eee6c34a864ff74 Mon Sep 17 00:00:00 2001 From: Dean Camera Date: Sun, 26 Dec 2010 13:01:37 +0000 Subject: Make a new general RingBuffer.h misc library driver, instead of the per-application LightweightRingBuff.h ring buffers. Change over projects to use the new driver. Add ORDERED_EP_CONFIG to the device Projects (only) that use only a single class driver, or where the endpoint ordering is fixed, to save on compiled binary size. Added new GCC_FORCE_POINTER_ACCESS() macro to correct GCC's mishandling of struct pointers. --- Projects/USBtoSerial/USBtoSerial.c | 13 ++++++++++--- 1 file changed, 10 insertions(+), 3 deletions(-) (limited to 'Projects/USBtoSerial/USBtoSerial.c') diff --git a/Projects/USBtoSerial/USBtoSerial.c b/Projects/USBtoSerial/USBtoSerial.c index 477dd44f5a..e775541fda 100644 --- a/Projects/USBtoSerial/USBtoSerial.c +++ b/Projects/USBtoSerial/USBtoSerial.c @@ -39,9 +39,16 @@ /** Circular buffer to hold data from the host before it is sent to the device via the serial port. */ RingBuff_t USBtoUSART_Buffer; +/** Underlying data buffer for \ref USBtoUSART_Buffer, where the stored bytes are located. */ +uint8_t USBtoUSART_Buffer_Data[128]; + /** Circular buffer to hold data from the serial port before it is sent to the host. */ RingBuff_t USARTtoUSB_Buffer; +/** Underlying data buffer for \ref USARTtoUSB_Buffer, where the stored bytes are located. */ +uint8_t USARTtoUSB_Buffer_Data[128]; + + /** LUFA CDC Class driver interface configuration and state information.
