INTRODUCTION

The purpose of this project is to manage lights and other systems (water levels, heater, solar panels, etc.) in a van running on a 12 volts battery
It runs on a Raspberry Pi Zero W and uses the GPIO port to interface with the electronic components
There is a basic electronic schema
The code is written in C++ and use raspberrypi_gpio project which is a C++ wrapper around the bcm2835 library

DEPENDENCIES

RASPBERRYPI_GPIO GIT REPOSITORY

The raspberrypi_gpio repository is connected to this repository via a git submodule.

COMPILATION

This project use make to compile. Here are the available make commands:
- all - build the project applying the release configuration
- debug - build the project applying the debug configuration
- clean - delete all generated files
- install - copy files (binaries and scripts) to the OS folders and register the service to make it run at startup
- uninstall - remove files (binaries and scripts) from the OS folders and unregister the service

Full install from fresh Raspberry Pi image flashed
