  This demo is based on the two GD32E51x-EVAL-V1.0 boards, it shows how to configure the 
CAN0 peripheral to send and receive CAN frames in FD mode. CAN-FD function is only valid 
in GD32E518 series. Before dispaly this demo, you should select GD32E518 for project device.

  In this demo, When KEY_B button is pressed, CAN0 sends a message to another board and 
print it. when CAN0 receives correctly this message,the receive data will be printed and 
LED2 toggles one time.  

  User can select one from the preconfigured CAN baud rates from the private 
defines in main.c.

  User must connect L pin to L pin and H pin to H pin of JP11 on the two boards 
for sending and receiving frames.And P2,P3 must be fitted.
