feat: Lyra Icons (#725) /!\ This PR depends on https://github.com/crosspoint-reader/crosspoint-reader/pull/732 being merged first Also requires the https://github.com/open-x4-epaper/community-sdk/pull/18 PR ## Summary Lyra theme icons on the home menu, in the file browser and on empty book covers ![IMG_8023 Medium](https://github.com/user-attachments/assets/ba7c1407-94d2-4353-80ff-d5b800c6ac5b) ![IMG_8024 Medium](https://github.com/user-attachments/assets/edb59e13-b1c9-4c86-bef3-c61cc8134e64) ![IMG_7958 Medium](https://github.com/user-attachments/assets/d3079ce1-95f0-43f4-bbc7-1f747cc70203) ![IMG_8033 Medium](https://github.com/user-attachments/assets/f3e2e03b-0fa8-47b7-8717-c0b71361b7a8) ## Additional Context - Added a function to the open-x4-sdk renderer to draw transparent images - Added a scripts/convert_icon.py script to convert svg/png icons into a C array that can be directly imported into the project. Usage: ```bash python ./scripts/convert_icon.py 'path/to/icon.png' cover 32 32 ``` This will create a components/icons/cover.h file with a C array called CoverIcon, of size 32x32px. Lyra uses icons from https://lucide.dev/icons with a stroke width of 2px, that can be downloaded with any desired size on the site. > The file browser is noticeably slower with the addition of icons, and using an image buffer like on the home page doesn't help very much. Any suggestions to optimize this are welcome. --- ### 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. Did you use AI tools to help write this code? _**PARTIALLY**_ The icon conversion python script was generated by Copilot as I am not a python dev. --------- Co-authored-by: Dave Allie <dave@daveallie.com>

feat: Implement fix for sunlight fading issue (#603) ## 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.
