Agree, the waveshare modules are great. They’re also (surprisingly) available via Amazon Prime, which is nice when you’re excited about a project idea and don’t want to wait 2-3 weeks for a shipment from China.
From my experience with this project, all ePaper displays _can_ do partial refresh, but some may have the drivers (LUT) included, others you might have to find some community-sources ones or design it yourself. In the post I link to my drivers for partial updates for the 4.2”, and in the footnotes there is a YouTube video going into lots of detail on how the drivers work if you wanted to write one or update it for a different display.
- pikewood 7y agoCould you send some links to the community you found who were hacking away on the partial refresh drivers? I have a 7.5" that I started with and would love to work off of whatever has already been accomplished.
- brettcvz 7y agoI link to a few helpful sources in the “references” part of the project readme: https://github.com/brettcvz/upnext/blob/master/README.md#references https://github.com/brettcvz/upnext/blob/master/README.md#ref... Hope that helps!
