//| Up to 30 RGB pins and 8 address pins are supported.
//| Tiled matrices, those with more than one panel, must be laid out `in a specific order, as detailed in the guide

//| At least 6 RGB pins and 5 address pins are supported, for common panels with up to 64 rows of pixels.
//| Some microcontrollers may support more, up to a soft limit of 30 RGB pins and 8 address pins.
//|
//| The RGB pins must be within a single "port" and performance and memory
//| usage are best when they are all within "close by" bits of the port.
