// Target Platform: EK-TM4C123GXL Evaluation Board
// Target uC:       TM4C123GH6PM
// System Clock:    40 MHz

// Hardware configuration:
// Red LED:
//   PF1 drives an NPN transistor that powers the red LED
// Green LED:
//   PF3 drives an NPN transistor that powers the green LED
// UART Interface:
//   U0TX (PA1) and U0RX (PA0) are connected to the 2nd controller
//   The USB on the 2nd controller enumerates to an ICDI interface and a virtual COM port
//   Configured to 115,200 baud, 8N1
