This project is a simple micropython pwm buzzer driver, which supports the application of uasycio to achieve multi-channel music playback, or multi-channels merged into one to achieve chord sound playback.

The method of composing music is more in line with the editing method of numbered musical notation.

Composers can compose music in python code in this way.

Currently only tested ESP32S2 chip.

After confirming the relevant documents, it has been determined that it should be compatible with all chips launched by Espressif that already support the micropython firmware , such as ESP8266,ESP32,ESP32S2,ESP32S3,ESP32C3.
