Library for the Adafruit alphanumeric backpack (using the HT16K33 chip)
I was putting together a project using 4 Adafruit featherwing LED backpacks (Adafruit product id 3130). That would give me a 16 character display. I would be using 4 i2c addresses, and wanted to hide the details of the i/o from my main sketch. Thus I thought I would build a library to handle the job. I used some of the code from the Adafruit libries, and wrote the rest. My library goes into a folder called AlphaDisp within the libraries folder.
