E-ink Pregnancy Tracker

A simple project that displays the status of a pregnancy using 2.7 inch e-Paper HAT by Waveshare. Meant to be run on a Raspberry Pi.

Setup

1. Configure your Raspberry Pi according to the docs provided by Waveshare.
2. Clone this repo:

   git clone https://github.com/grappeq/e-ink-pregnancy-tracker.git
   

3. Install dependencies:

   pip3 install -r requirements.txt
   

4. Install libopenjp2 required by Pillow:

   sudo apt-get install libopenjp2-7
   

5. Copy the config.json.example file as config.json and set the expected birth date.
6. Configure cron to run the main.py file on a schedule (e.g. every 30 mins).

Testing

If you wish to try out the package locally, you can run the local_test.py file. The script generates the image and displays it on your screen without the need of relying on packages that are available only on Raspberry Pi.
