This is a set of utilities to inspect and debug the CAN bus. Via a graphical user interface you can gain insight into what is happening.

Usage

$ python explorer.py socketcan:vcan0

Or for some more low level utilities, such as candump and cansend:

$ python cansend.py socketcan:vcan0 88 deadbeef

$ python candump.py socketcan:vcan0

For the purpose of pure bus traffic, a sine wave generator script was made. Caution: this creates pretty random bus traffic!

$ python sinewave.py --freq 10 socketcan:vcan0

Testing

Setup a virtual can bus:

$ sudo ip link add dev vcan0 type vcan
$ sudo ip link set up vcan0
