Raspberry Pi Service Collection

Setup

Python Virtual Environment

The services need to run in a virtual environment on the Raspberry Pi.

Create a Virtual Environment

1. Install the required packages from apt:

   sudo apt install python3-venv python3-pip
   sudo apt install --upgrade python3-setuptools

2. Clone the repo from github:

   git clone https://github.com/jmgrady/rpi-setup

3. Create the virtual environment and install CircuitPython:

   cd hw-services
   ./new-venv

   A reboot will probably be required when complete.

4. Synchronized the venv with the pinned drivers:

   ./update-venv

   If requirements.in has been modified or to update the versions of the python dependencies, run update-venv with the build option. This will first update requirements.txt with the new module requirements.

Setup Services

Display IP

To setup the Display IP service, run:

ansible-playbook install-display-ip.yaml --limit <IP of RPi>, -K

Temperature Logger

To setup the Temperature Logger service, run:

ansible-playbook install-temp-logger.yaml --limit <IP of RPi>, -K

Notes

1. There must be a comma after the IP address of the Raspberry Pi so that Ansible does not interpret the IP address as a hostname.
