This is a buffer based led matrix library for Arduino that has cascadable led matrix boards using Max7219. It is very fast because all display updates are done in memory buffer and only written to hardware when necessary. It is designed to aim at game development using led matrix.
The hardware design is based on Max7219 and can be purchased from oMJKZZ on eBay (http://www.ebay.com/itm/390547465770?ssPageName=STRK:MESELX:IT&_trksid=p3984.m1555.l2649) or any other compatible boards.
