00002  * Simple demo to demonstrate communication via UART2
00003  *
00004  * Hardware requirements:
00005  *  - FRDM-KL25Z board
00006  *  - USB-UART protocol converter (FTDI cable or similar)
00007  *
00008  *  Wiring: 
00009  *    FTDI RX to PTE22, FTDI TX to PTE23
00010  *    FTDI GND to GND, FTDI 5V to Vin
