This is a library for our I2C LED Backpacks | |
Designed specifically to work with the Adafruit LED Matrix 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 | |
Adafruit invests time and resources providing this open source code, | |

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 | |
