LED lights with CAN bus control, mainly used for demonstrations. It can be displayed in a loop or can be used to control the display after receiving CAN commands.
CAN communication has hardware filtering settings that only receive data with the specified CAN ID. For other data, the hardware is directly shielded, reducing the burden on the MCU to process data.
In the early stage of debugging, a serial port was used for data indication. Not demonstrated in the actual video.
Based on the above: the MCU resources used are:
1. Serial port
2.GPIO
3.CAN Fifo
Finally, here is a comparison chart between the 3D simulation and the real thing:
