Currently Klipper firmware has support for only one UART with hardcoded use as interface to the Klipper itself. I have several printers that have external touch screen control modules connected through UART to the main board. And I can see that it became some kind of industry standard to use such …

This has been raised a few times before. I’m not aware of anyone currently working on it. It’s fine if someone wishes to add support. In the past there was [WIP/draft] - serial bridge - mks/bigtreetech uart lcd support by etet100 · Pull Request #3885 · Klipper3d/klipper · GitHub . It’s possible …

It would certainly be great to to have some use for all those Touchscreens that turned black with Klipper taking over!

If you need help @lanserge hmu. I could code something.

Thank you for willing to help. I will try to create some C skeleton first with some implementation for stm32 and will post info here. After that we could discuss next required steps to make it done fully and properly.

Yes please. IF anybody is able to code in the DWIN T5. I am happy to build a UI to bring the screens back to life.

Hi all, Bad news here: Question regards to the repo · Desuuuu/klipper · Discussion #147 · GitHub Looks like Desuuuu has lost interest to ‘UART channel’ topic, but his code looks good and nice. Do we have a chance to merge Desuuuu’s changes? What else needs to be done? I saw Contributing to Klipp…

I dont know the state of this but could this not be reopened now that we have the developments in regards to can2040. https://github.com/Klipper3d/klipper/pull/3885 The argument Kevin makes regarding having it be a makemenu selection of the feature doesnt apply anymore now that we have the rp2040 …

I would also highly appreciate the DWIN T5 touchscreen support for my Ender 6 (currently running on a ~1yr old Klipper modification by Desuuu)! Unfortunately I don’t know how I could help on this, as my knowledge on UART and programming in general is too weak.

Hi all, I was looking into implementing this feature for klipper. My idea is to add a serialcmds.c with commands to: configure an unused serial port (other than the host serial port if that’s used for communication with the MCU), queue to send data out to the serial port, and read any received dat…
