[AIOT] CanBus for Tinker Board 3N
The Linux CAN is depending on the SocketCAN:
https://en.wikipedia.org/wiki/SocketCAN
1. Run the CAN testing script (CAN loopback mode) and reboot device after running script:
Please use the bellowing command with root privilege by “sudo su” command in Debian and “adb root” in Android
Note: The testing files: can_loopback.sh, can_tx.sh, can_rx.sh
CAN_test_scripts.zip
~/code/CAN/CAN_test$ sudo ./can_loopback.sh
[sudo] password for asus:
Start can tx/rx loop with iface can0 !
candump: no process found
20:21:51.967: can0 send 001#0011223344556677
can0 001 [8] 00 11 22 33 44 55 66 77
can0 001 [8] 00 11 22 33 44 55 66 77
20:21:51.975: can0 receive can packet
….
~/code/CAN/CAN_test$ sudo reboot
2. Use two devices A (Sender) and B (Receiver)
In B device (Receiver): refer can_rx.sh
# ip link set can0 down
# ip link set can0 up type can bitrate 125000
# candump can0
In A device (Sender): refer can_tx.sh
# ip link set can0 down
# ip link set can0 up type can bitrate 125000
# cansend can0 001#0011223344556677
3. Then we can see the dump message in B device
can0 001 [8] 00 11 22 33 44 55 66 77
can0 001 [8] 00 11 22 33 44 55 66 77
