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. --- Projects/Magstripe/Magstripe.c | 13 +++++++++++-- 1 file changed, 11 insertions(+), 2 deletions(-) (limited to 'Projects/Magstripe/Magstripe.c') diff --git a/Projects/Magstripe/Magstripe.c b/Projects/Magstripe/Magstripe.c index 5cd107e9a..871db28c3 100644 --- a/Projects/Magstripe/Magstripe.c +++ b/Projects/Magstripe/Magstripe.c @@ -39,6 +39,8 @@ USB_ClassInfo_HID_t Keyboard_HID_Interface = .ReportINEndpointNumber = KEYBOARD_EPNUM, .ReportINEndpointSize = KEYBOARD_EPSIZE, + + .ReportINBufferSize = sizeof(USB_KeyboardReport_Data_t), }; int main(void) @@ -70,6 +72,12 @@ void SetupHardware(void) /* Hardware Initialization */ Magstripe_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 ReadMagstripeData(void) @@ -113,9 +121,10 @@ void EVENT_USB_UnhandledControlPacket(void) USB_HID_ProcessControlPacket(&Keyboard_HID_Interface); } -void EVENT_USB_StartOfFrame(void) +ISR(TIMER0_COMPA_vect, ISR_BLOCK) { - USB_HID_RegisterStartOfFrame(&Keyboard_HID_Interface); + if (Keyboard_HID_Interface.IdleMSRemaining) + Keyboard_HID_Interface.IdleMSRemaining--; } uint16_t CALLBACK_USB_HID_CreateNextHIDReport(USB_ClassInfo_HID_t* HIDInterfaceInfo, void* ReportData) -- cgit v1.2.3
