ws_ledc
High-level interface for the ESP32/ESP32-Sx/ESP32-Cx LED Control (LEDC) peripheral. Instead of specifying a timer or channel, this class automatically allocates a channel and associates it with a pin. Underlying esp32-hal-ledc performs timer management and handles the low-level LEDC peripheral API calls.
