Overview
Adafruit's 16x24 Red LED Matrix Panel uses the HT1632C LED driver. The driver has the ability to dim and flash and they can be chained together to produce large displays. The code developed for this MiniProject is based on Adafruit's original HT1632 github repository. It also uses a modified version of BoneHeader.h to support C++ originally from Andrew Miller's github repository.
The
Inputs and Outputs
A single matrix panel can be powered directly off of the BeagleBone's 3.3V supply (running only on USB power). The interface is a bit-banged serial interface requiring 3 pins: chip select (active low), write clock (rising edge trigger), and data.
