This repository contains the firmware for the different Libre Solar Charge Controllers based on Zephyr RTOS.
Coding style is described here.
The main branch is used for ongoing development of the firmware.
Releases are created from main after significant updates have been introduced to the firmware. Each release has to pass tests with multiple boards.
A release is tagged with a version number consisting of the release year and a release count for that year (starting at zero). For back-porting of bug-fixes, a branch named after the release followed by -branch is created, e.g. v21.0-branch.
The firmware documentation including build instructions and API reference can be found under libre.solar/charge-controller-firmware.
In order to build the documentation locally you need to install Doxygen, Sphinx and Breathe and run make html in the docs folder.
