It is like the Universal Serial Bus (USB) or ethernet that we can find in many of our modern computers. As mentioned, RS485 is used to link devices instead of other means as it provides significant advantages. However, in a full-duplex setup, they are limited to a master and slave communication where slaves cannot communicate with each other. Commercial aircraft cabins also use RS485 for low-speed data communications. ------------------------------------------------------, Please reboot your raspberry pi to apply all settings, git clone https://github.com/Seeed-Studio/seeed-linux-dtoverlays, export CUSTOM_MOD_LIST="CAN-HAT"; make all_jetsonnano, sudo cp overlays/jetsonnano/2xMCP2518FD-spi0.dtbo /boot, sudo /opt/nvidia/jetson-io/config-by-hardware.py -n "Seeed 2xMCP2518FD". Tap the following command ++python grove_sound_sensor.py 0++ in the command line interface. Connect 2-Channel CAN-BUS(FD) Shield for Raspberry Pi (MCP2518FD)'s Channel 0 L -> 2-Channel CAN-BUS(FD) Shield for Raspberry Pi (MCP2518FD)'s Channel 1 L, Connect 2-Channel CAN-BUS(FD) Shield for Raspberry Pi (MCP2518FD)'s Channel 0 H -> 2-Channel CAN-BUS(FD) Shield for Raspberry Pi (MCP2518FD)'s Channel 1 H. This is an example of sending and receivce CAN-BUS data (up to 64 bit) using the FD Protocol on its own using the 2-Channel CAN-BUS(FD) Shield for Raspberry Pi (MCP2518FD).
