  This demo is based on the GD32H75EY-EVAL-V1.0 board, it shows how to configure the 
CAN2 peripheral to send CAN frames, and CAN1 peripheral to receive CAN frames in normal mode.

  When WAKEUP button is pressed, CAN2 sends a message to CAN1, when CAN1 receives correctly 
this message,the receive data will be printed and LED3 toggles one time. 

  User must connect L pin to L pin, and H pin to H pin of JP14 and JP16 on the board for sending and 
receiving frames.

  GD32H75EY-EVAL-V1.0 board CAN transceiver needs 5V power supply.
