pwm (by Iswahyudi)
i have a trouble with pwm output.
please give me example to set it. (i want to have a frequency between 0-2000 hz by adc pin 2. I mean when I give input to pin 2 then I have pwm frequency at pin 16 value 0-2000 hz) thanks a lot.

Hi,
The PWM output frequency is a fixed value (ex; 2000Hz) only the pulse width is variable (or duty cycle)... NOT THE FREQUENCY 0% = ______________________________ 10% = _________-_________-_________- 50% = _____-----_____-----_____----- 90% = _---------_---------_--------- 100 = ------------------------------ So PWM is not the instruction you are looking for... you may try to use a super short cycle time and turn ON and OFF a coil on every cycle and try to reach your target of 2000Hz See the following basic example
