PIDevice_MAX7219_LED_MATRIX Class (console safe)
MAX_7219 LED MATRIXA class to control a MAX7219_LED_MATRIX device via SPI interface on Raspberry PI.
One to eight such LED_MATRIXES can be controlled, by daisy chaining them.
(Daisy chaining is in theory supported but has not been tested when this is written since one of 2 displays that I had was broken, but I got more on the way so this will be revisited).
This class exists on all the platforms for Cross compile purposes but it only actually does something on the Linux ARM target (Raspberry PI)PIDevice_MAX7219_LED_MATRIX plugin is a Xojo plugin interfaces one or more MAX7219_LED_MATRIX devices.
