Hello
It seems that the frequency of PWM signals is not configurable for Teensy boards. For all other boards, the achievable frequency is updated according to the desired frequency, but as soon as you choose the Teensy board, the achievable frequency remains stuck at 490.2Hz.

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.
