+ * main.c
+ *	CE2812
+ *  Created on: Dec 10, 2021
+ *  Author: Trevor Barnes
+ *  Description: This program allows the user to control the led bar on the dev board. Users can
+ *  flash the leds or scan them back and forth like the lights on KITT from Knight Rider. The speed
+ *  of the lights can also be adjusted and returned back. This is all controlled through a serial
+ *  terminal using the usart.
