sagyman:
Can anybody tell me how to do pwm every 2 cycles?
I set timer 3 to be 120Hz and I want pulse every 2 cycles
This doesn't make sense to me. If you interfere with the PWM signal after every 2 cycles how can it be a PWM signal?
Do you really mean that you want it to emit two cycles at 120Hz (i.e. for a total of 2/120 = 16.67 millisecs) and then what?
