Raspberry Pi OS setup

Image download and install

• Download a Raspberry Pi OS image from https://www.raspberrypi.org/software/operating-systems/. Lite version is recommended as we won't need any window manager nor applications.
• Write the image on a SD card the way you prefer :)
• Mount the SD card on your computer

SSH setup

• Go to the mounted boot SD card partition and create a ssh file: touch /<path_to_mounted_boot/ssh

Wifi setup

• Create a wpa_supplicant.conf in the mounted boot folder and fill it with the following lines:

country=COUNTRY-CODE
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1

network={
    ssid="NETWORK-NAME"
    psk="NETWORK-PASSWORD"
}

Obviously, you need to replace NETWORK-NAME and NETWORK-PASSWORD with your wifi network credentials. COUNTRY-CODE is your country code following ISO-3166 standard.

Final steps

• Insert the SD card in your Raspberry Pi and power it up.
• Identify your Raspberry PI IP address on your router once is powered up.
• Connect via SSH to its IP address ssh pi@(password israspberry` by default)
• Run raspi-config: sudo raspi-config
  • Change pi user password (recommended)
  • Under Interfacing options:
    • Enable Camera
    • Enable SSH
    • Enable SPI

Motor pins setups

You now need to wire the motors shield to the Raspberry Pi.

Setup controller app

• Clone the setup repository: git clone git@github.com:raspycar/setup.git
• Change current directory to the setup dir
• Install ansible: pip install ansible
