NOTE: CANard is no longer recommended. Please use python-can for future python development with CANable applications
CANard is a python library that allows you to easily communicate on the CAN bus from Python. The library supports connecting to CANable/CANtact devices directly with PySerial, so it works well on both Windows and Linux systems without a kernel CAN module.
I have a fork of CANard available that fixes a couple of issues and is compatible with both Python 2 and Python 3.
CANard also supports native socketcan devices such as a CANtact/CANable initialized with slcand.
Getting started is quite simple:
"""Connect to CANable; print and echo any received frames""" from canard import can from canard.hw import cantact dev = cantact.CantactDev("/dev/ttyACM0") # Connect to CANable that enumerated as ttyACM0 dev.set_bitrate(1000000) # Set the bitrate to a 1Mbaud dev.start() # Go on the bus count = 0 while True: count += 1 frame = dev.recv() # Receive a CAN frame dev.send(frame) # Echo the CAN frame back out on the bus print(str(count) + ": " + str(frame)) # Print out the received frame
