Topic: PWM high frequency (Read 68 times) previous topic - next topic


Hi guys!

Since the max frequency of the analogWrite() function is 490 (980) Hz I wanted to ask for the best method to increase it. I read about some different approaches and I am not sure which one is the smartest. I need a frequency of at least 20kHz, while still being able to change the duty cycle and frequency.

Any answer is appreciated. :)


How about some links to the different approaches? It could save some time.
  ... with a transistor and a large sum of money to spend ...
Please don't PM me with technical questions. Post them in the forum.


The search pulled up a few items for the frequency you wanted but this one sounds promising

See the magnifying glass icon at the top of the screen ?
Yep the one right at the top that says "Search"


It may not be the answer you were looking for but its the one I am giving based on either experience, educated guess, google (who would have thunk it ! ) or the fact that you gave nothing to go with in the first place so I used my wonky crystal ball.
