EasilyĬreating virtual modules to prototype CAN bus communication.īrief example of the library in action: connecting to a CAN bus, creating and sending a message:ġ #!/usr/bin/env python 2 3 """ 4 This example shows how sending a single message works. Prototyping new hardware modules or software algorithms in-the-loop. Modern cars, motorcycles, boats, and even wheelchairs have had components tested Testing of hardware that interacts via CAN. For example monitoring aĬommercial vehicle using its OBD-II port. Passively logging what occurs on a CAN bus. More concretely, some example uses of the library: Linux such as a BeagleBone or RaspberryPi. With commercial CAN to USB devices right down to low powered devices running Python-can runs any where Python runs from high powered computers The python-can library provides Controller Area Network support forĭifferent hardware devices, and a suite of utilities for sending and receiving HUD ECU Hacker can also install the drivers that you need for all supported adapters.īelow you see the CAN bus Terminal connected to a DENI E1700 ECU.Īll data traffic can be logged into a HTML logfile.Toggle table of contents sidebar python-can # Read the very detailed help file about the different types of adapters. These adapters connect to any computer via USB. You can use a cheap Chinese J2534 adapter ($30 - $40 USD) to connect to the CAN bus. HUD ECU Hacker runs on Windows XP, 7, 8, 10, 11 (32 and 64 bit). HUD ECU Hacker is charityware, which means that you can use it unrestricted, but you are asked to give a donation to an NGO of your choice if you use the program frequently. It has a built in CAN Raw Terminal which allows to manually send CAN bus commands and see the responses.Īpart from the CAN Raw protocol HUD ECU Hacker also implements the ISO 15765 protocol which allows to send longer messages than only 8 bytes. It shows the entire traffic on CAN bus in real time and allows to set filters for specific ID ranges. There is a new software: HUD ECU Hacker for analyzing vehicle ECUs over K-Line and CAN bus.
