Stephen Dickey / Mbed 2 deprecated C027_CANInterfaceComm

This tests the CAN interface between two LISA C027 MBED Boards. By connecting the two boards, pins 1,2,3 respectively on the CAN interface, and loading and executing this code on BOTH boards, CAN messages will be received, and printed, on the PC-USB console interface of both devices.
