Week Two - Struggles with SPI, and the LED Driver

In order to gain maximum utilization of the tri color LED board, we experimented with the SPI functionality of the HCS12 Microcontroller and get multiple colors working in the game. Unfortunately, how the exact functionality could be obtained was very unclear and we could not implement the system in a way to yield the desirable effects.

After several days of experimenting with the SPI and LED drivers, we decided it was the best route to conserve our time and produce a project with tangible results. We decided that we will use Ports A, B, and T along with decoders in order to drive the LED board in a single color.
