avr 38khz modulation problems
February 19, 2011
I have some troubles... I take a look at AVR Calc and at 8mhz I can make a CTC of around 37.98khz signal wich lets say would be ok for 38... the problem is that there is not enough explanation of how to make it...
for 8mhz, 1 prescaller, ,on 8 bit timer:
OCR = 0xD2
TCNT Base = 0x2D
CTC = 37.9147khz
Error = -0.224%
overflow: 32.000 uSec
PWM normal/fast = 31250.000 hz
pwm phase correct 15686.274hz
can you please help me how to set the code for this?
I mean I know the prescaller etc how to set... I get trouble with toggle/clear/set bits etc etc....
please I need code for tiny2313 and mega8 :(
