pyvit: Python Vehicle Interface Toolkit
pyvit: Python Vehicle Interface Toolkit
pyvit is a toolkit for interfacing with cars from Python. It aims to implement common hardware interfaces and protocols used in the automotive systems.
Install
pip install pyvit
Use
Using a CANtact
The CANtact tool is directly supported by pyvit. It should work on Windows, OS X, and Linux.
Example
This example goes on bus and prints received messages:
from pyvit import can
from pyvit.hw.cantact import CantactDev
dev = CantactDev("/dev/cu.usbmodem1451")
dev.set_bitrate(500000)
dev.start()
while True:
print(dev.recv())
You will need to set the serial port (/dev/cu.usbmodem1451 in this example) correctly.
SocketCAN
SocketCAN interfaces are supported, however, they are only available on Linux. Using SocketCAN requires Python 3+
Example
The device can now be accessed as a SocketCanDev. This example goes on bus and prints received messages:
from pyvit import can
from pyvit.hw import socketcan
dev = socketcan.SocketCanDev("can0")
dev.start()
while True:
print(dev.recv())
Using Peak CAN Tools
Peak CAN tools (also known as GridConnect) are supported through SocketCAN. This functionality is only available on Linux
For kernels 3.6 and newer, skip to step 5.
- Download the Peak Linux driver.
- Install dependencies:
sudo apt-get install libpopt-dev
- Build the driver:
cd peak-linux-driver-x.xx make sudo make install
- Enable the driver:
sudo modprobe pcan
- Connect a Peak CAN tool, ensure it appears in /proc/pcan. Note the network device name (ie, can0)
- Bring the corresponding network up:
sudo ifconfig can0 up
