Python svd2json package

This package converts a CMSIS SVD (System View Description) file into a more friendly JSon format than raw XML to JSon conversion. The aim of this package is to ease code generation from SVD file. We state that JSon format is the best suitable for this purpose. For instance, it can be used as-is in Jinja2 template processing.

JSon format

The resulting JSon root node is the device node in SVD. XML values are converted to equivalent JSon ones.

NOTE: Some SVD files might be inconsistent in peripherals and/or registers naming convention across devices or in a single SVD file. E.g. only few registers are prefixed by peripheral name but no others, you can optionally trim this prefix in order to keep code generation as simple as possible and reusable among a wide range of devices/mcu. !!ADD REF!!

An Additional interrupts is added in the resulting JSon which collects all interrupts declared across all peripherals. This can ease, for instance, VTOR table generation, one only has to walk through this array.

Script

This package exports the following script:

svd2json

$ svd2json --help
usage: svd2json [-h] -s SVD output

convert svd file to json

positional arguments:
  output             output filename

options:
  -h, --help         show this help message and exit
  -s SVD, --svd SVD  SVD file to convert

How to ...

This package follows PEP517/518/621 for its build system using a single pyproject.toml file and setuptools with dynamic versioning as build-backend. Unit testing, linting etc. are done with tox. The minimal python version is Python 3.10.

Build

One can use any python build front-end. E.g. with PyPA build front-end :

python -m build

Lint

This package is linted by black and flake8. In case of conflict between those two linter, we choose to follow black rules by default as it is closer to PEP8 than flake8.

tox -e lint
