I made a little weather doodad primarily to get this Inkplate 10 working under the ESP-IDF, but also to flesh out my little C framework of IoT functionality (the framework also exists as a win32 directx app that can host the code but i've not included that with the Inkplate project specifically).
The readme has operating/building details. I had to use LPGL 3.0 to license it due to me using some similarly licensed code as a reference for this implementation (but it was Arduino - yuck)
