Observable CAN BUS Driver

• This is a linux "driver" that can be used to listen to can bus events
• The notification follows the Observer design pattern
• The canlistener runs in a separate thread

usage

# motor example
from listener import listener, motor
from canobservable import canlisten

# connect to canbus interface
canbus = canlisten(
    interface   = "can",
    baudrate    = 250000
)

# listening the motor at this channels
m = motor(
    desc        = "motor", 
    on          = [0x00, 0x11, 0x55, 0x88]
)

canbus.add_listener(m)

# log
print(canbus)
input("PRESS RETURN to continue :>")

# create can thread
canbus.start()

Replay

• You can replay canbus logs using canfilereplay

from canfilereplay import *

canreplay = canlistenfromfile(
    pathtofile = "{___PATH_TO_FILE__}",
    replayfrequency = 0.1
)

canreplay.add_listener(
    motor(
        desc = "motor", 
        on = [0x500, 0x460]
    )
)

print(canreplay)
canreplay.start()

run

sudo pip install python-can
sudo python3 main.py
