Scripts I created for a dashboard-like screen rendered on an e-paper display.

• Raspberry Pi Zero W
• Raspberry Pi Pico W
• Waveshare Pico e-Paper 3.7in

These can be installed by running the following command after cloning the repository:

pip install -r rpiDashboard/ZeroW/requirements.txt

• cachetools
• certifi
• charset-normalizer
• contourpy
• cycler
• fonttools
• google-api-core
• google-api-python-client
• google-auth
• google-auth-httplib2
• google-auth-oauthlib
• googleapis-common-protos
• httplib2
• idna
• kiwisolver
• matplotlib
• numpy
• oauthlib
• packaging
• Pillow
• protobuf
• pyasn1
• pyasn1-modules
• pyparsing
• python-dateutil
• requests
• requests-oauthlib
• rsa
• six
• uritemplate
• urllib3

• image-magick

The Pi Zero W fetches data from the following APIs:

• Tankerkönig API (used for getting gas prices)
• Google Calendar API (syncing my google calendar events)
• Weatherapi

In addintion it also formats the current date and time.

Most of the data is stored in a plain text file called formattedData.txt. The gas prices are stored in a database, which is then used to draw a graph with time on the x and price on the y-axis.

The graph is exported as an image and converted to a bytearray. The script used for that is img_to_bytearray.py. It requires image-magick to be installed on the system for it to work.

Lastly the data is wirelessly sent to the Pi Pico W.

The Pi Nano W connects to the local Wi-Fi.

Upon recieving the data from the Pi Zero W, the Pico generates an output for the e-Paper display and displays the dashboard-screen.
