From 7c5444b89a49df7cb671b0b041567990d2a3012e Mon Sep 17 00:00:00 2001 From: Dean Camera Date: Tue, 2 Jun 2009 10:54:32 +0000 Subject: Removed new Start of Frame event from the library; performance suffered far too much and it was only useful in one of the standard classes (HID). Altered HID demos to use the previous method of tracking millisecond periods via a hardware timer rather than the SOF events. Fixed MIDI class driver blocking on unread events to the host. --- Demos/Device/KeyboardMouse/KeyboardMouse.c | 21 +++++++++++++++------ 1 file changed, 15 insertions(+), 6 deletions(-) (limited to 'Demos/Device/KeyboardMouse/KeyboardMouse.c') diff --git a/Demos/Device/KeyboardMouse/KeyboardMouse.c b/Demos/Device/KeyboardMouse/KeyboardMouse.c index 8f6a573a67..71a8375aa6 100644 --- a/Demos/Device/KeyboardMouse/KeyboardMouse.c +++ b/Demos/Device/KeyboardMouse/KeyboardMouse.c @@ -41,7 +41,7 @@ USB_ClassInfo_HID_t Keyboard_HID_Interface = .ReportOUTEndpointNumber = KEYBOARD_OUT_EPNUM, .ReportOUTEndpointSize = HID_EPSIZE, - .ReportBufferSize = sizeof(USB_KeyboardReport_Data_t), + .ReportINBufferSize = sizeof(USB_KeyboardReport_Data_t), .IdleCount = 500, }; @@ -53,7 +53,7 @@ USB_ClassInfo_HID_t Mouse_HID_Interface = .ReportINEndpointNumber = MOUSE_IN_EPNUM, .ReportINEndpointSize = HID_EPSIZE, - .ReportBufferSize = sizeof(USB_MouseReport_Data_t), + .ReportINBufferSize = sizeof(USB_MouseReport_Data_t), .ReportOUTEndpointNumber = 0, .ReportOUTEndpointSize = 0, @@ -85,7 +85,13 @@ void SetupHardware() /* Hardware Initialization */ Joystick_Init(); LEDs_Init(); - USB_Init(); + USB_Init(); + + /* Millisecond timer initialization, with output compare interrupt enabled for the idle timing */ + OCR0A = ((F_CPU / 64) / 1000); + TCCR0A = (1 << WGM01); + TCCR0B = ((1 << CS01) | (1 << CS00)); + TIMSK0 = (1 << OCIE0A); } void EVENT_USB_Connect(void) @@ -115,10 +121,13 @@ void EVENT_USB_UnhandledControlPacket(void) USB_HID_ProcessControlPacket(&Mouse_HID_Interface); } -void EVENT_USB_StartOfFrame(void) +ISR(TIMER0_COMPA_vect, ISR_BLOCK) { - USB_HID_RegisterStartOfFrame(&Keyboard_HID_Interface); - USB_HID_RegisterStartOfFrame(&Mouse_HID_Interface); + if (Keyboard_HID_Interface.IdleMSRemaining) + Keyboard_HID_Interface.IdleMSRemaining--; + + if (Mouse_HID_Interface.IdleMSRemaining) + Mouse_HID_Interface.IdleMSRemaining--; } uint16_t CALLBACK_USB_HID_CreateNextHIDReport(USB_ClassInfo_HID_t* HIDInterfaceInfo, void* ReportData) -- cgit v1.2.3
