Review – Maxim MAX7219 LED Display Driver IC. Use the Maxim MAX7219 LED display driver with Arduino in Chapter 56 of our Arduino Tutorials.
The first chapter is here, the complete series is detailed here. Sooner or later Arduino enthusiasts and beginners alike will come across the MAX7219 IC. And for good reason, it’s a simple and somewhat inexpensive method of controlling 64 LEDs in either matrix or numeric display form. Furthermore they can be chained together to control two or more units for even more LEDs. Playground - LedControl. LedControl a Arduino library for the MAX7221 and MAX7219 These two chips provide an easy way to control either an array of 64 Led's or up to 8 digits of 7-segment displays.
MAX7219CNG LED Matrix/Digit Display Driver [MAX7219] ID: 453 - $9.95. Playground - LEDMatrix. There are different solutions for driving this popular piece of hardware from the Arduino.
If you are not familiar with the MAX7219 or MAX7221 you should start by reading the hardware related documents The MAX72XX-datasheet The The MAX7219 and MAX7221 Led drivers article, with schematics and some additional information related to the Arduino. Multiplexing the MAX72xx to drive a 2 Color Matrix - using an alternating shutdown method to control a 2 color matrix with 2 MAX72xx. The software for driving these chips is covered on several pages:
