Detailed Description

Part of Adafruit's Arduino library for our I2C LED Backpacks: -—> http://www.adafruit.com/products/ -—> http://www.adafruit.com/products/

These displays use I2C to communicate, 2 pins are required to interface. There are multiple selectable I2C addresses. For backpacks with 2 Address Select pins: 0x70, 0x71, 0x72 or 0x73. For backpacks with 3 Address Select pins: 0x70 thru 0x77
