## Adafruit 7 segment i2c hex configuration.txt
The Adafruit 1.2" 4 digit 7-segment LED display with backpack (https://www.adafruit.com/product/1270) is connexted via the i2c bus interface. Adafruit has a quite good soldering & setup tutorial at https://learn.adafruit.com/adafruit-led-backpack/1-2-inch-7-segment-backpack, however they do a terrible job of describing in easy detail the necessary i2c writes to control the display from a language other than their provided libraries for Arduino or Python. So I've assembled a pretty comprehensive address and data to write in order to fully control the display. Please see attached images for some details.

digit segment numbered.jpg      - shows an image of the display, along with numbers/letters along with a bitmask to use to control each segment.
seven segment bitmask chart.jpg     - shows which bits control which segments for the digits
dots segment bitmask chart.jpg  - shows which bits control which segments for the dots

Examples of writing are using the Linux i2c-tools. For example this write:

i2cset 1 0x
