Raspberry Pi Installation Guide

This guide provides step-by-step instructions for setting up the Raspberry Pi for the Payload Computer Drone Project.

Introduction

Follow the sections below to prepare your Raspberry Pi for use in the project.

Connect the Raspi as discribed in the PX4 dokumentation and make sure you use the same bit rate as used in your start file.

Install the Picamera2 package.

sudo apt install python3-picamera2

Clone and install the repo into a virtual environment on the Raspi. Make sure include-system-site-packages is set to true, else it will not be able to access the raspicam package.

Configure the config file as needed by your system and requierements.

Autostart

Only do this when you want the script to start on every boot.

mkdir -p ~/.config/systemd/user
code ~/.config/systemd/user/start_droneos.service

Then add this to the file, make sure that you replace /home/aviator/ to the absolute path to your install directory of the package.
