Feature request: implement fade features for ledc #518
Description
Hardware support for fading leds is neat and I'd like to use it in one of my projects.
If nobody is currently working on this, I can take a look at implementing it.
The fade feature in esp32 hardware is described here: https://docs.espressif.com/projects/esp-idf/en/stable/esp32/api-reference/peripherals/ledc.html#change-pwm-duty-cycle-using-hardware.
