Hello everyone, I'm new here. I want a code that allows me to change the PWM duty cycle and frequency for a pin. Can such a thing be done? Thank you

[image] alexandru99: change the PWM duty cycle and frequency for a pin That's possible. It will affect all channels that depend on the same timer.

@alexandru99 The answer depend on board you using.

I am using arduino uno. Can you help me with a code?

[image] alexandru99: I want a code that allows me to change the PWM duty cycle and frequency for a pin. Can such a thing be done? Why ?

i have an engine who is controlled from a throtlle with frequency between 150-1050hz and duty cycle 15-85(%).Not it is defect so now I'm trying to make a circuit that copies this pedal. I don't know how much the frequency should increase according to the duty cycle, but I want to make these variables to test and thus figure out what I should do to make everything work normally

Here is an example of controlling both frequency and duty cycle on a uno type device: https://www.gammon.com.au/forum/?id=11504&reply=6#reply6

[image] DrDiettrich: It will affect all channels that depend on the same timer. Is it true? Keeping the frequency same, the duty cycles of the channels (A/B) could be different in Mode-14.

…or, you could try software PWM , which will allow you to control the frequency and doody-cycle much more precisely.

Can I change PWM duty cycle and frequency on the same pin?
