Re: TIMER 2

hi martin thanks for the reply my desired frequency is 40Hz therefore from your reply i did the following using timer 2 i set prescaler rate 1:16 postscaler 1:13 rollover 256 for nearest value to 40 is 37.560 Hz then i did preload = 256 - (8000000/4x16x40) = 3125 therefore 256 - 3125 = -2869 ??? ive...
