  This demo is based on the GD32E517Z-EVAL-V1.0 board, it shows how to set a communication 
with the CAN in loopback mode.

  The example first performs a transmission and a reception of a standard data frame by 
polling at 125 Kbps.If the received frame is successful, the LED2 is on. otherwise,the LED3 
is ON. 
    
  User can select CAN0 or CAN1 or CAN2 cell using the private defines in main.c.
