NOVA Dashboard

Commands:

• yarn start - start development server in http://localhost:3000
• yarn build - Builds the app for production to the build folder for the best performance.

Setup NOVA Dashboard on Raspberry PI 3

Parts List

• Raspberry Pi 3
• Heatsinks - (keep that CPU cooler)
• Screen - todo: defined which screen
• DC-DC converter (12v input to 5v usb) - Power Pi in the car
• Powerblock for safe power on and power off

Pi setup

Get the OS image installed

1. Download RASPBERRY PI OS LITE onto micro SD card.
2. Put SD card in Raspberry Pi, connect HDMI and keyboard

Initial Configuration

• Boot Rasperry PI and login with user: pi and password: raspberry
• Run sudo raspi-config
• Go to Localisation Options -> WLAN Country -> Select PT Portugal
• Go to System Options -> Wireless LAN -> SSID: HOMELAN2 PASSWORD: qwerty123456
• Go to Interface Options -> Enable SSH
• Go to System Options -> Hostname -> Write novadash
• Finish / Save and reboot sudo reboot

We're now able to connect through SSH (ifconfig wlan0)

• On main computer run ssh pi@IP and password: raspberry
• Run sudo raspi-config
• Go to System Options -> Boot / Auto Login -> Console Autologin
• Go to System Options -> Network at Boot -> NO
• Save and reboot
• Update everything sudo apt-get -y update && sudo apt-get -y upgrade ; sudo apt-get autoremove - this will take a while
• Reboot sudo reboot

Setup Video driver

This will setup the video driver along with chromium browser

• Run sudo apt-get install libgl1-mesa-dri
• Run sudo raspi-config
• Go to Advanced Options -> A7: GL Driver -> GL (Fake KMS)
• Reboot sudo reboot

Chromium and x11 setup

The bare minimum we need are X server and window manager. Let’s install just that:

• Run sudo apt-get install --no-install-recommends xserver-xorg x11-xserver-utils xinit openbox
• Run sudo apt-get install --no-install-recommends chromium-browser

Configure xserver / Chromium

openbox is now installed; let's make it so our window's manager starts up chromium (auto start stuff comes later)

• Edit file sudo nano /etc/xdg/openbox/autostart

# Disable any form of screen saver / screen blanking / power management
xset s off
xset s noblank
xset -dpms

# Allow quitting the X server with CTRL-ATL-Backspace
setxkbmap -option terminate:ctrl_alt_bksp

# Start Chromium in kiosk mode
sed -i 's/"exited_cleanly":false/"exited_cleanly":true/' ~/.config/chromium/'Local State'
sed -i 's/"exited_cleanly":false/"exited_cleanly":true/; s/"exit_type":"[^"]\+"/"exit_type":"Normal"/' ~/.config/chromium/Default/Preferences
chromium-browser --kiosk --disable-overscroll-edge-effect --disable-sync --disable-suggestions-ui --disable-signin-promo  --mmal-frame-copy --mmal-frame-buffers=4 --ignore-gpu-blacklist --enable-native-gpu-memory-buffers --start-maximized --disable-infobars 'http://localhost:8080'

• Example only: To start chromium now: type startx -- -nocursor
• Example only: To quit chromium/x server - hit Ctrl-Alt-Backspace

Auto Start Server

1. Edit file sudo nano /home/pi/.bash_profile

cd ~/nova-dashboard && bash init.sh

Forcing monitor resolutions

1. Run sudo nano /boot/config.txt -> find, uncomment and set:

framebuffer_width=800
framebuffer_width-480
