Description

How do i change the PWM frequency?

I tried using standard the Arduino functions

ledcAttach(PWM_PIN, FREQ, RESOLUTION); ledcWrite(PWM_PIN,pwm_value);

Both are undefined.

Please tell me how to set the PWM frequency, resolution, and duty cycle.

Thanks

Sketch

ledcAttach(PWM_PIN, FREQ, RESOLUTION);
 ledcWrite(PWM_PIN,pwm_value);

There is no example for PWM itself, It shows a tone generator example, and servo example, but those doesnt allow direct control of the PWM.

The proper PWM functions ledcAttach(PWM_PIN, FREQ, RESOLUTION); and ledcWrite(PWM_PIN,pwm_value); are undefined in arduino.

Im trying to control a DC motor (not a servo, and not a stepper) just a regular DC motor using the PWM, where i need to change both the frequency and duty cycle.
