Using the Waveshare CANbus hat. Right now i’m just trying to get the host adapter working. I’ve edited config.txt, created the can0 network interface, enabled spi in raspi-config, and physically connected the board. But somehow it isn’t able to search for devices. What am I missing?
In the first image you have an error indicating the file is unwritable at the bottom. Did you use sudo to write that file, and are you sure it saved? Also, did you reboot after doing everything?
i didn’t use sudo when opening it to take that screenshot. the file is saved and i rebooted.
Same here. Try to get my Spider Board running with CAN bus.
I also use the Waveshare HAT. But no matter what I do it will not run.
If I use candump I only see this:
pi@pi0test:~ $ candump can0
can0 3F0 [1] 00
can0 3F0 [1] 00
Looks to me if no data would be send when I call canbus_query.py.
ip a is showing that the CAN bus is running.
Did you manage the problem?
