  This demo is based on the GD32F503V-EVAL-V1.1 board and demonstrates how to configure the 
CAN peripheral to send and receive CAN frames in normal mode. Since the GD32F503V-EVAL-V1.1 
board has only one transceiver for CAN0, testing requires a hyperterminal and CAN box.

  When the Tamper button is pressed, CAN0 sends a message to the CAN box, and the transmitted 
data is displayed through the hyperterminal.

  When the CAN box sends a message to CAN0, the received data is shown on the hyperterminal 
upon successful reception, and LED1 toggles once.

  Note that the CAN transceiver on the GD32F503V-EVAL-V1.1board requires a 5V power supply, 
so a DC power supply must be used.
