Web16 okt. 2024 · I read that PWM on all pins is 490/980Hz by default, but can be adjusted up to 8MHz by adjusting the timers. Then reading into some Marlin documentation I discover that D6 uses TIMER4A. This looks like a custom timer breakout that doesn't quite fit the naming convention I've seen elsewhere on guidance for changing frequency. WebStep5 – Decide on the required PWM Frequency for the selected channel. It can be anything, but for our LED dimming example let’s set it to 1kHz or (1000Hz). Step6 – Configure this PWM Channel with the selected frequency & resolution using this function. 1 ledcSetup(PWM_Ch, PWM_Freq, PWM_Res);
