Ws2812b-pio

Implements SmartLedsWrite for the Raspberry's RP2040 using the PIO peripheral.

Refer to the rp-hal for examples.


lib.rs:

WS2812 PIO Driver for the RP2040

This driver implements driving a WS2812 RGB LED strip from a PIO device of the RP2040 chip.

You should reach to [Ws2812] if you run the main loop of your controller yourself and you want [Ws2812] to take a hold of your timer.

In case you use cortex-m-rtic and can't afford this crate to wait blocking for you, you should try [Ws2812Direct]. Bear in mind that you will have to take care of timing requirements yourself then.
