The CAN Message Generator is a Python script designed to generate C source and header files for Controller Area Network (CAN) messages based on the Database (DBC) files. It simplifies the process of creating C files for CAN messages by automating the generation process and providing a customizable template mechanism.
- Loads CAN message definitions from DBC files.
- Automatically generates C source and header files for CAN messages.
- Provides a customizable template system for generating the files.
- Supports scaling, signed and unsigned signals, and floating-point data types.
-
Make sure you have Python 3 installed on your system.
-
Install the required dependencies using
pip:
pip install cantools mako click
- Download or clone the repository containing the script files.
To use the CAN Message Generator, follow these steps:
-
Prepare the JSON configuration file (ex.
configs/example.json) with your desired settings. (use an existing or make your own .json file in that folder) -
Run the script with the JSON configuration file as the argument:
python canal_parser.py configs/example.json
- The script will read the configuration from the JSON file, process the DBC files, and generate the C source and header files based on the specified templates.
The configuration file (ex. configs/tms.json) allows you to customize various aspects of the generation process, such as:
- Paths to DBC files and output directories.
- Template locations for C source and header files.
- Ignored DBC files.
- Enabling or disabling file migration.
Please refer to the provided sample tms.json file for an example of the configuration settings.
The CAN Message Generator uses the Mako template engine to generate the C source and header files. You can customize the templates to match your specific project requirements. The templates are located in the specified template directories (TEMPLATE_LOCATION) in the configuration file.
