LedControl (LedControl.h)

LedControl - a Arduino library for the MAX7221 and MAX7219 http://playground.arduino.cc/Main/LedControl -- There is already a library and a lot of code-examples for the Arduino and the MAX72XX available, but the focus had always been on controlling Leds layed out in some sort of rectangular matrix. I use the MAX72XX to drive 7-segment displays, so I wanted a function to display numbers (decimal and hexa-decimal) and also the limited set of alphanumeric characters that make (visual) sense on this kind of displays. But the library also provides a basic set of functions by which either individual or groups of Leds can be switched on and off.

    Could you guys update to the latest from their repo? They updated to set the 128-byte array they use to utilize PROGMEM, which is a huge amount of memory moved to flash instead of SRAM. I had to upload the newest version manually under a new name to CodeBender just to use it in my project, which only has 2KB of SRAM and gets pushed over it's limit by the version you guys currently have.
