Timer0 Reload based on ADC result

[Cyborg]

My ADC value is 200 (50 Hz) and my new table has 72 entries from 0 to 350 in steps of 5.

timer0 reload value = FFFFh - 5Mhz / (36*(8/4)(200)) = 65535 - 347 = 65188

If you haven't changed the prescaler it should work according to your equation.

5MHz/(72*(8/4)*(200)) = 5MHz/28,800=173.6

65,535-173=65,362!

If you go by equation 3 in AN900 it would be around 65,447 for a reload value.

I will test the software on my development board and see if I get a sine wave of 50Hz or not. Maybe Proteus is not simulating the program at the right clock speed.

Thanks
