  2. Install operating system image to SD card. See https://www.raspberrypi.org/documentation/installation/installing-images/
  3. run raspi-config to setup network settings (if you want to use Wi-Fi), hostname, change password etc...
  4. Update packages. apt-get update && apt-get upgrade.
  5. Install some required packages. apt-get install unclutter.

Setup Raspberry Pi devices

Camera

  1. Enable camera module by raspi-config command. See Camera configuration for more details.
  2. Connect camera module by FFC (Flexible Flat Cable).

HyperPixel

  1. Insert HyperPixel into GPIO port.
  2. Follow instructions in HyperPixel driver

Install Smart Shopping Navigator demo applications

Copy files to Raspberry Pi.

$ git clone https://github.com/groovenauts/SmartShoppingNavigator.git
$ cd SmartShoppingNavigator/raspberrypi/files
$ rsync -auz home/pi/ /home/pi/
$ sudo rsync -auz etc/ /etc/

Create device in Cloud IoT Core

The corresponding device resource should be created in Cloud IoT Core. Please read Creating Registries and Devices for details.

During creating device in Cloud IoT Core, you should create device key pairs to authenticate the device. Smart Shopping Navigator demo applications support only ES256 key. Please generate ES256 key pair.

And copy private key file to Raspberry Pi as /home/pi/ec_private.pem.

Create config file

Edit /home/pi/watchdog.conf to specify the GCP project, Cloud IoT registry/device.

Enable services

$ sudo systemctl enable capture
$ sudo systemctl enable dashboard
