This project generates a bitmap image displaying weather and calendar for today and tomorrow. I use this in my kitchen to allow my family to see daily updates without requiring use of a traditional screen or mobile phone.
It is intended for display on a 7.5" e-Paper screen such as the Waveshare E-ink display w/ Raspberry Pi HAT. Docs are available here
Install the HAT on the Raspberry Pi and connect to the Waveshare e-Ink display. Follow the instructions on Waveshare links to enable SPI, then run the install script which summarizes much of what was discussed there:
./einkscripts/install.sh
Then, install the python dependencies:
pip3 install -r python/src/requirements.txt
You can run the script to build just the bitmap:
python3 src/generator
This will query the relevant services and create a bitmap to disk. By default images are stored in the bitmaps/ folder named by timestamp. You can build this to develop on a device that is not connected to the e-Ink display.
You can use the --file option to select a different destination.
python3 src/generator --file local.png
When running on the Raspberry Pi with the e-Ink display connection, run the script
with the --display option:
python3 src/generator --display
That will write the image to the actual display (as well as save it to disk).
