This demo is based on the GD32A508Z-EVAL-V1.0 board, it shows how to configure the
CAN0 and CAN2 peripheral to send and receive CAN frames in normal mode， and please use
the GD-Link power supply（5V）.

When KEY_B button is pressed, CAN0 sends a message to CAN2 and print it.
when CAN2 receives this message correctly, the receive data will be printed and LED2
toggles one time.

User must connect L pin to L pin and H pin to H pin between JP11(CAN0) and JP17(CAN2) on boards
for sending and receiving frames.And JP18, JP19 must be fitted to CAN0.
