----
This is basically an nsh configuration (see above) with added support
for CAN driver. Both CAN 1 (RX: PB_8, TX: PB_9) and CAN 2 (RX: PB_5, TX: PB_6)
are turn on.
Functionality of CAN driver can be tested by calling application
"can" in NuttShell. This application sends 100 messages over CAN 1.
