Setup Raspberry Pi

Hardware

- Raspberr Pi Official USB-C Power Supply
- Raspberry PI 4 Computer, Model B 8GB RAM
- PureLink CInema Seriers Micro HDMI - HDMI Cable (CS1200-030)
- M2.SDD via USB-3.0

Image

https://downloads.raspberrypi.org/raspios_arm64/images

Note: Do make sure to use arm not armhf imges.

SSH-Access

Add an empty ssh file within the boot folder of the image.

host => raspberrypi.local
username => pi
paswword => raspberry

ssh [email protected]

Remove local cached fingerpint for IP on your device

ssh-keygen -R 192.168.1.2

Settings (manually)

Ddisable Sleep Mode Dispaly

Firmeware Update

sudo apt-get upgrade -y
sudo rpi-eeprom-update
sudo rpi-eeprom-update -a

Installation

Prerequisites

Install Chromedriver and Selenium

  • pre Updates
sudo apt-get update
sudo apt-get install -y curl unzip xvfb libxi6 libgconf-2-4
  • Install chromedriver

Get Chromedriver from electron GitHub release. Make sure it supports the installed chromium version on your Pie! Make sure you downloaded the right os version. ARM64 Tipp: To get versions Enter chromium --product-version Or chromedriver --product-version after download unzip

Driver

sudo wget https://github.com/electron/electron/releases/download/v12.0.18/chromedriver-v12.0.18-linux-arm64.zip
unzip chromedriver-v12.0.18-linux-arm64.zip

Make sure to configure ChromeDriver on your system (move the chromedriver to /usr/lib)

sudo mv chromedriver /usr/bin/chromedriver
sudo chown root:root /usr/bin/chromedriver
sudo chmod +x /usr/bin/chromedriver

sudo reboot

After this everything should be set up. In case you installed the wrong version of chromedriver. removing chrome driver:

sudo rm -f /usr/bin/chromedriver 
sudo rm -f /usr/local/bin/chromedriver 
sudo rm -f /usr/local/share/chromedriver

Clone Github Repository

Make sure you have a ssh public key and have access to the repository

ssh-keygen
cat ~/.ssh/id_rsa.pub

git clonehttps://github.com/codebar-ag/raspberry-pi-kiosk

Install Pyhton Dependencies

install all python dependencies. on raspi os explicitly use 'python3' & 'pip3' commands to call python. run:

pip3 install -r requirements.txt

Set Up the Config.

To use autostart config has to be set up correctly. NOTE! SECRETS SHOULD NOT BE VISIBLE IN GIT AND USED WITH ENV VARS.

Add the Enviroment Variable AUTH_TOKEN with the right AuthToken to CWD. In Terminal at (CWD, where the autostart.py is).

cp .env.dist .env
export AUTH_TOKEN="YOUR_TOKEN"

or create a .env file inside the CWD. place the ENV Var their. the Config script will automaticly load the token. from the config.yaml.

Configuration

sudo raspi-config

GL Driver

Advanced Options / GL Driver / G2 GL (Fake KMS)

Enable the compositor.

Advanced Options / Compositor / Yes

Chrome

Plugins

Chromium on Raspberry Pi OS comes with uBlock Origin and h264ify extensions installed by default. Make sure that h264ify is enabled, so YouTube uses h264-encoded videos for which the Raspberry Pi supports hardware-accelerated video decode.

Flags

chrome://flags/#enable-accelerated-video-decode
chrome://flags/#ignore-gpu-blocklist

Autostart

sudo nano /etc/xdg/lxsession/LXDE-pi/autostart

WARNING: The (CWD) Current Working Director the autostart directory! Change on Directory up to autostart

cd /home/pi/Scripts/autostart/

then run with python3
