Addresable led strip WS2812 guide.

I want to add WS2812 to my T20. How to add PWM pin to device configuration or something like that.

You would need to add a code block similar to this, but for the RADIO_T20, and would need to configure it appropriately for that target. i.e. you need a suitable free GPIO, Timer, and DMA handler. After that, the rest of the code should pretty much automatically work, as it is looking for LED_STRIP_GPIO to be defined to enable the rest of the necessary support.

Beware that it was not added because the internal 5v rail cannot power it, so you will need to add a power circuit
