## Summary * **What is the goal of this PR?** The goal of this PR is to deliver a fix for or at least mitigate the impact of the issue described in #561 * **What changes are included?** This PR includes a new option "Sunlight Fading Fix" under "Settings -> Display". When set to ON, we will disable the displays analog supply voltage after every update and turn it back on before the next update. ## Additional Context * Until now, I was only able to do limited testing because of limited sunlight at my location, but the fix seems to be working. I'll also attach a pre-built binary based on 0.16.0 (current master) with the fix applied to the linked ticket, as building this fix is a bit annoying because the submodule open-x4-sdk also needs an update. * [PR in open-x4-sdk](https://github.com/open-x4-epaper/community-sdk/pull/15) needs to be merged first, we also need to add another commit to this here PR, updating this dependency. * I decided to hide this behind a default-OFF option. While I'm not really concerned that this fix might potentially damage the display, someone more knowledgeable on E-Ink technology could maybe have a look at this. * There's a binary attached in the linked issue, if someone has the required sunlight to test this in-depth. --- ### AI Usage While CrossPoint doesn't have restrictions on AI tools in contributing, please be transparent about their usage as it helps set the right context for reviewers.
