Raspberry Pi Setup

This article will introduce to you, how to set up a Raspberry Pi from scratch with all software needed to run the detector hardware.

DISCLAIMER: If not stated otherwise, this tutorial is developed on Raspian 10 Buster.

Initial Setup

1. Requirements: Raspberry Pi version 3 or above (with 40-pin GPIO connector)
2. Create a fresh install of Raspbian Buster operating system e.g. from here on microSD card (with or without desktop)
3. Enable I2C Interface: In terminal: sudo raspi-config >> Interfacing Options >> I2C>> Enable: Yes >> Reboot optional
4. Enable SSH: The SSH protocol is needed if you want to remotely configure your hedless Raspberry Pi. In a terminal: sudo raspi-config >> Interfacing Options >> SSH >> Enable: Yes >> Reboot
5. Configure the network connection:

• Per default, the RPi is configured to automatically obtain an IP address when a connection is available and DHCP in your local network is active (this should be the case for most local/home networks).
• If you prefer a fixed IP address in a local network: edit the /etc/dhcpcd.conf. Use the template and uncomment the "Example Static IP Configuration" section with your desired IP address.
• If network access should be established via WiFi, follow these steps:
  • Make sure that the wpa_supplicant package is installed:

sudo apt install wpasupplicant

• • edit the file /etc/wpa_supplicant/wpa_supplicant.conf

sudo nano /etc/wpa_supplicant/wpa_supplicant.conf

it should look like this:

update_config=1
country=DE

network={
       ssid="<your network ssid>"
       psk="<your wifi password>"
       key_mgmt=WPA-PSK
}
