This program exercises many of the peripherials including serial communication (prints bargraph on screen), as well as pushbutton (SW1 and SW2) and led red/blue usage. Based on Freescale program: frdm_helloworld, see http://developer.mbed.org/teams/Freescale/code/frdm_helloworld/?platform=FRDM-K64F REVISIONS: PC.BAUD = 115200-FAST, ADDED MSG STRINGS
