Universal Calibration Protocol for Python

Project description


Codacy Badge Maintainability Build Status Build status Coverage Status GPL License

pyXCP is a lightweight Python library which talks to ASAM MCD-1 XCP enabled devices. These are mainly, but not only, automotive ECUs (Electronic Control Units).

XCP is used to take measurements, to adjust parameters, and to flash during the development process.

XCP also replaces the older CCP (CAN Calibration Protocol).


pyXCP is hosted on Github, get the latest release:

Alternatively, get pyxcp from PyPI:

pip install pyxcp


  • Python >= 3.6

  • A running XCP slave (of course).

  • If you are using a 64bit Windows version and want to use seed-and-key .dlls (to unlock resources), a GCC compiler capable of creating 32bit executables is required:

    These .dlls almost always ship as 32bit versions, but you can't load a 32bit .dll into a 64bit process, so a small bridging program (asamkeydll.exe) is required.
