From 0ce2950d811b8dc11e46602e7490d795d8ddfb5d Mon Sep 17 00:00:00 2001 From: Dean Camera Date: Mon, 8 Nov 2010 03:41:48 +0000 Subject: Added board hardware driver support for the Adafruit U4 breakout board. Fixed calculation of timer register reload values derived from F_CPU; must subtract one from the division result for the compare value to be correct. Change AVRISP-MKII rescue clock speed to 4MHz to ensure that a 125KHz ISP speed works regardless of the target's fuses (i.e. DIV8 set). --- Projects/AVRISP-MKII/Lib/V2Protocol.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'Projects/AVRISP-MKII/Lib/V2Protocol.c') diff --git a/Projects/AVRISP-MKII/Lib/V2Protocol.c b/Projects/AVRISP-MKII/Lib/V2Protocol.c index e2c658673..618dedb43 100644 --- a/Projects/AVRISP-MKII/Lib/V2Protocol.c +++ b/Projects/AVRISP-MKII/Lib/V2Protocol.c @@ -61,7 +61,7 @@ void V2Protocol_Init(void) #endif /* Timeout timer initialization (10ms period) */ - OCR0A = ((F_CPU / 1024) / 100); + OCR0A = (((F_CPU / 1024) / 100) - 1); TCCR0A = (1 << WGM01); TIMSK0 = (1 << OCIE0A); -- cgit v1.2.3
