Arduino Library for MAX7219 Serially Interfaced, 8-Digit, LED Display Drivers
It is very unfinished at the moment, but the basics should work
Based upon MaxMatrix by Oscar Kin-Chung Au
This is currently (and most likely will always be) a one-man project for my own education and general fooling around.
Obviously there are already numerous implementations and libraries to talk to the MAX7219 or MAX7221 LED-driver-ICs from Arduino (or similar) boards. However, none pleased me personally and the above linked one was the first library I got working by stripping it down to it's bare essentials. I am now slowly re-adding the functionality in a way that makes sense to me. Hopefully this might be useful for someone stumbling across.
- Add support for 7-Segment displays as well as LED-Matrices
- Add more core functionality like Text display (see original Library)
- Make it all efficcient (Talk to all matricies instead of one at a time)
