This is a library for our I2C LED Backpacks
|
||
|
|
|
||
|
|
Designed specifically to work with the Adafruit LED 7-Segment backpacks

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
