/**
* MAX7219 Debug Matrix
*
* Add support for a low-cost 8x8 LED Matrix based on the Max7219 chip, which can be used as a status
* display. Requires 3 signal wires. Some useful debug options are included to demonstrate its usage.
*
* Fully assembled MAX7219 boards can be found on the internet for under $2(US).
* For example, see https://www.ebay.com/sch/i.html?_nkw=332349290049
