I've been using KOReader on my reMarkable Paper Pro and I'm addicted to it! The toolbox is amazing and provides great reading experience in contrast with the native OS. One last missing piece for me though is the ability to scribble on some of the textbooks I have on KOReader, and that's how I've came across the project. At the moment I've used evtest to see what type of input events are firing up with the pen and this is the output, I've marked some insightful bits of the data sample for a simple quick touch with the pen: root@imx8mm-ferrari:~# evtest No device specified, trying to scan all of /dev/input/event* Available devices: /dev/input/event0: 30370000.snvs:snvs-powerkey /dev/input/event1: Hall effect sensors /dev/input/event2: Elan marker input /dev/input/event3: Elan touch input Select the device event number [0-3]: 2 Input driver version is 1.0.1 Input device ID: bus 0x1c vendor 0x0 product 0x0 version 0x0 Input device name: "Elan marker input" Suppo
Just really wanted to request Kindle Scribe support, been looking for pencil support for koreader for a while now so Ill be following your progress!
Hello and thank you SO much for what you're doing here! So, so needed and I'm excited to try it for the first time on my Kobo Libra Colour!! I see the eventual intention is an export method. I just want to suggest here that I would love for WebDAV to be supported in this when that day comes. Thanks again!
