So I have been working on this on my own time, I am a potential CE student. This was an assignment for someone who gave it to me along with caped BBB. I am running barebones using CCS and a TI XDS100v2 USB Debug Probe/CortxA8 sim. They wrote this program as an LCD driver using the I2C1 bus from

RE: [beagleboard] Re: I2C driver for a PCA9685 servo controller board for s90 servos
