  This demo is based on the GD32H75EY-EVAL-V1.0 board, it shows how to configure the 
CAN1 and CAN2 peripheral to send CAN frames, and CAN0 peripheral to receive CAN frames
in normal mode. CAN0 uses the mailbox to receive data from CAN1 and uses the FIFO to 
receive data from CAN2.

  When TAMPERbutton is pressed, CAN1 sends a message to CAN0, when CAN0 receives correctly 
this message,the receive data will be printed and LED3 toggles one time.

  When WAKEUP button is pressed, CAN2 sends a message to CAN0, when CAN0 receives correctly 
this message,the receive data will be printed and LED4 toggles one time.

  Connect the CANL pins of JP14, JP15, and JP16 together, and connect the CANH pins together.

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