PWM has been changed to support different frequencies. Try the latest daily build. |

Awesome ! , using latest nightly solved it. |

@kthod861 please close the issue if all right |

This changes storage.mount() to require that a mount point exist on the parent file system. A bug in background tasks is also fixed where the function parameter is cleared on pending callbacks during "reset". Disk usage is shown on the directory listing and changes based on the mounted file system. Writable is also loaded per-directory. Fixes micropython#8108. Fixes micropython#8690. Fixes micropython#8107.

Hello,
While trying to get the same behavior as "ledc"+"ledcWriteTone" using micropython, i ended up stuck with no solution to get the 8 PWM output with different frequencies .
Goal: get 8 frequencies outputs (fixed duty) that can be modified using python as the ESP32 is able to provide this ( tested using ledc on a bare new ESP32 board).
But i probably have missed something here.
For example, using "esp32-20210902-v1.17.bin", and by default testing the example provided here is a fail:
i say fail as the output of it i absolutly not :
PWM(Pin(15), freq=100, duty=64, resolution=10, mode=0, channel=0, timer=0)but rather:
PWM(Pin(15), freq=100, duty=64 )Did also a ton of test by myself without understanding the logic behind mode and channel selection when creating a PWM object.
It sounds like it dynamically choose timers depending on init frequency but i'm really not sure about that.
Any help is welcome
