LPC11Cxx The CCAN on-chip drivers example

Detailed Description

Example description
This example shows how to use CCAN on-chip driver to send and receive a simple CAN frame.
Upon reset, the LPC11C00 will send a simple CAN frame with ID 0x345. It will send a CAN frame with its data contents of "TEST".
Whenever the LPC11C00 receives a CAN frame whose ID is between 0x400-0x4FF, it will simply resend the received frame back onto the CAN bus.
The baudrate is set to 500kBit/s.

Special connection requirements
Connect the CCAN_L and CCAN_H signal from the LPC11C00 to a CAN BUS Analyzer.
