An EFX-TEK customer asked for a demo for the Adafruit 7-segment I2C backpack; I thought I'd share here, too. There's not a lot of memory in the BS2 so I try to keep things trim. The demo runs a simple counter.

The trick with the Adafruit display is understanding:
-- the HT16K33 uses 16 bits per character (only 8 are used in 7-segment displays)
-- the Adafruit module maps digit 2 to the colon, so we have code around this

BTW... the Prop-2 referenced in the program is the EFX-TEK Prop-2 controller, an industrialized BS2
