Hello Judicael,
For Teensy boards, the PWM frequency can indeed be configured, but it requires a specific approach. Here’s how you can adjust the PWM frequency:
Use the analogWriteFrequency(pin, hz) Function: This function allows you to set the PWM frequency for a specific pin. By calling analogWriteFrequency(pin, desiredFrequency); you can change the frequency to your desired value. This is a straightforward method to adjust the frequency directly.
Note that changing the frequency with analogWriteFrequency() should always be preceded by analogWrite(0) and followed by a new analogWrite(newDutyCycle) to make sure that the duty cycle is recalculated depending on the new PWM frequency.
Regards.
