NoTouchScreenFirmware VS BIGTREETECH-TouchScreenFirmware

NoTouchScreen firmware for btt tft35: https://github.com/teeminus/NoTouchScreenFirmware

I don't have one, but I've heard it "works" (to the degree that such a screen can with Klipper) using this firmware for the screen.

Firmware: I have flashed both the SKR Mini e3 v2 (below) and the TFT35''s NoTouch firmware.

I flashed it with this: https://github.com/teeminus/NoTouchScreenFirmware (Need to make sure you're using the screen's SD port and not the skr mini's one)

I've been using the NoTouchScreenFirmware on mine. It works okay most of the time, but occasionally it will glitch and start displaying random symbols until I do a FIRMWARE_RESTART to fix it.

I was able to get basic status out of a skr1.4, tft24 and klipper with this: https://github.com/teeminus/NoTouchScreenFirmware. One thing that had me stuck is you need to flash the TFT24 as though you were going to use marlin, and then put the notouch flash on top of it.

I flashed https://github.com/teeminus/NoTouchScreenFirmware to the TFT to get a working Klipper display. Unfortunately I don't think there's any way to get touch capability right now.

I've never seen the 3dwork site before, thanks for that! Look at the settings/config options here and see if they map into that site. Also make sure to check if you need "serial_port_2 1". That was a key for me, everything else was configured correctly but the motherboard wasn't talking to the screen.

When I go here https://github.com/bigtreetech/BIGTREETECH-TouchScreenFirmware The wirring is gone all of the sudden for some random reason or i am blind

You can't do much to change the menu contents and almost nothing to change the menu structure in config.ini. That's why I wrote you'd have to edit the firmware source files, such as the Menu files under https://github.com/bigtreetech/BIGTREETECH-TouchScreenFirmware/tree/master/TFT/src

Thanks for the ideas. According to the readme, the TFT35 v2.0 only has the RS232 connection, not the EXP connections. It's bolted into my case, I haven't unbolted it yet to visually check for myself. And, according to the readme, the TFT35 v2.0 only supports touchscreen mode, not Marlin mode.

Per this site, to get full functionality you need to:
