I am new to the forum and just found out about XLights and FPP.  I have long been a RPi fan and recently started using the Pico for WS2812 LED strip designs. I have developed Pico software that uses the 8 co-processors for WS2812 drive of 8 strings. 

I have tested the device and find that I can drive 8 strings of 300 pixels at 100 Hz update rate.  See the Google Drive video link to the prototype hardware below:

Pico X8 Strings

I am very impressed with XLights and I have been helping my son-in-law use the Kulp K16-AB.  Very nice hardware design and great FPP software!

As I understand it, the FPP software for the Raspberry Pi supports a "Channel" option for adding new remote controllers.  How can I find out more in order to develop a driver for my prototype? I am sure that the Pico and RPi can be set up to communicate at a pretty high rate.

I would be happy to release the software as Open Source.  It is based on the single channel Pico development kit code for driving WS2812 strings with a Pico co-processor with some custom code for glue.
