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/TempDataLogger/TempDataLogger.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'Projects/TempDataLogger/TempDataLogger.c') diff --git a/Projects/TempDataLogger/TempDataLogger.c b/Projects/TempDataLogger/TempDataLogger.c index c572a38707..c3cfd65f90 100644 --- a/Projects/TempDataLogger/TempDataLogger.c +++ b/Projects/TempDataLogger/TempDataLogger.c @@ -208,7 +208,7 @@ void SetupHardware(void) TWI_Init(); /* 500ms logging interval timer configuration */ - OCR1A = ((F_CPU / 1024) / 2); + OCR1A = (((F_CPU / 1024) / 2) - 1); TCCR1B = (1 << WGM12) | (1 << CS12) | (1 << CS10); TIMSK1 = (1 << OCIE1A); -- cgit v1.2.3
