Touch screen on 2560 rev 3

Hi, everybody. A quick question, do You think is possible to use tft touch 3.5" with this board?

Hi.


My answer will not be satisfactory. It is too theoretical.

Theoretically, everything is possible provided that the appropriate electrical connections are made and the appropriate code is written to handle the new components.

From what I know used firmware supports alphanumeric (character) displays.

@ _kaktus_

Seems is a direct flow you <=> me.
What I'm looking for is a schematic of the gray strip wiring board <=> lcd, so I can understand if is possible to do a pcb to connect tft-pcb-board

You will read it from the controller board schema published in the forum as well.


Well, you know, in China now is the middle of the night.

Until I can help you, you can count on me. I respect people who want to achieve something, are kind and honor others.

GOOD DAY!

@Ricky1966
You need to refer to the sch file and the UART fw info.
Then try to edit.(You can refer to the news of the Marlin official community)

@ William

Tks for your help, I don't know if where you live is midnight or no .
About your kind answer, I've decifrate sch file like schematic, and I've, and UART fw, like UART forwarting? Right? I want to look out also the GTM32 schematic. If I not mistaken, the board use tft instead lcd.

Hi.


Depending on the printer model, an alphanumeric or graphic display is connected to this controller board.

@ _kaktus_

Yes, ok, but if board could be lcd o tft connected, schematic maybe lead me to understand pinout

I will tell you that the circuit diagrams are in the subforum control board.
