The rest of this page is for developers of the jacdac-python library.

This section explains how to develop this library locally.

sudo apt update
sudo apt upgrade
sudo apt install --upgrade -y python3 python3-pip ipython3 python3-venv python3-libgpiod

You can develop this package from a GitHub codespace container. No configuration changes is needed, follow the regular installation steps.

The devtools web site will be forwarded by GitHub and you will be able to connect to physical hardware from the browser while testing the Python running on the codespace container.

You'll need a JacHAT for Raspberry Pi and you will need to build bridge executable, see https://github.com/microsoft/jacdac-stm32x0/tree/main/spibridge

Install the build tools

python -m pip install --upgrade -r requirements.txt

Create the library bundle

python -m build

The build system uses Angular commit syntax to automatically generate releases.

The devtools script allows to run a Jacdac dashboard connected through a websocket. This allows to pipe packets from the python library into the web developer tools and diagnose issues over there

To launch the developer tools server (once per session)

python -m jacdac.devtools

With the devtools running, you can run snippets from the examples folder:

python -m examples.blinky
