This project is an example of how to describe peripherals with an intermediary layer (YAML files) which can be used to generate library files for a peripheral.

It can also generate reference documentation for a peripheral, useful for embedding into datasheets.

The tool works well for I2C devices, while SPI support is in progress.

This is not an official Google product.

Note: This project requires Python3. You can install using pip

pip install cyanobyte

cyanobyte-codegen -t templates/doc.md -o ./build peripherals/MCP4725.yaml

• -t - A template file. You can provide multiple template files.
• -o - The output directory where files will be generated.
• -e - The directory that emboss folder is stored.
• -d - Debug flag to print out additional information.
• -c - Clean the output directory before generating files.

One or multiple files can be passed as an argument.

rm -rf ./build

cyanobyte-validator peripherals/MCP9808.yaml

One or multiple files can be passed as an argument.

The current spec is described in docs/cyanobyte.md. You can find all examples in the peripherals/ directory.

python3 -m pylint --rcfile=test/pylintrc cyanobyte/*.py
python3 -m pylint --rcfile=test/pylintrc test/sampleData/*.py

python3 -m unittest test.test_codegen

The templates directory includes a set of canonical templates which can be used with this codegen tool.

The peripherals directory includes a set of peripheral description files that have been created along with the project. It is not an exhaustive list.
