uses the library found here : https://github.com/waveshare/e-Paper
I used a wavershare 2.13 e-Ink display purchased from The PiHut : https://thepihut.com/collections/raspberry-pi-display-hats/products/three-colour-2-13-eink-display-phat-red-black-white
display.py accepts two numbers: outside temperature and inside temperature.
If a third param is set to "f" then the display does a full refresh rather than a partial refresh, which can get messy after a while.
display.py -0.1 22.2
to do a full refresh:
display.py -0.1 22.2 f
a wrapper script which I use to get tempertures from a ds18b20 attached to the Pi and a local URL which delivers the outside temperature is called "show.sh" syntax:
show.sh [f]
the "f" executes a full refresh
