pyA2L

pyA2L is an ASAM MCD-2MC processing library written in Python.

ASAM MCD-2MC, also known as ASAP2, is a non-XML file format for defining calibration parameters, measureable variables, and communication interface specific parameters, widely used in automotive applications.

ASAP2 is typically used together with CCP (CAN Calibration Protocol) or XCP (Universal Calibration Protocol).

Supported Versions: 1.6

Installation

• Via pip:

  $ pip install pya2ldb

  IMPORTANT: Package-name is pya2ldb NOT pya2l!!!

• From Github:

  • Clone / fork / download pyA2Ldb repository.
  • Make sure you have a working Java installation on your system, like AdoptOpenJDK or OpenJDK.
  • Download and install ANTLR 4.11.1:
    • curl -O -C - -L https://www.antlr.org/download/antlr-4.11.1-complete.jar
    • Add ANTLR to your CLASSPATH environment variable, e.g.: export CLASSPATH=$CLASSPATH:~/jars/antlr-4.11.1-complete.jar (you may put this in your .bashrc, .zshrc, ...).
  • Run setup-script: python setup.py develop

Getting Started

here is a basic example:

from pya2l import DB
import pya2l.model as model

db = DB()
base_dir = "examples/"
a2l_file = "ASAP2_Demo_V161"
try:
    session = db.import_a2l(f"{base_dir}{a2l_file}.a2l")
except OSError:
    print("a2ldb for this file already exists, using it instead")
    session = db.open_existing(f"{base_dir}{a2l_file}.a2ldb")

measurements = session.query(model.Measurement).order_by(model.Measurement.name).all()
for m in measurements:
    print(f"{m.name:48} {m.datatype:12} 0x{m.ecu_address.address:08x}")
