Hi Ricky.
:mrgreen:

If you look at the GTM2630 rev 3.0 controller board schematic you will see a description of the connector leads to the LCD module.

Hi.
:mrgreen:

A link with the description of this module would be helpful.
Some signal names are characteristic for the SPI bus.

Is this connector dedicated to the selected display model :?:

It's a Raspberry's tft shield. Yes it's SPI. What I want to know, if I can replot the pinout for the lcd on board to drive tft. Probably I must to change it on Marlin on someone of the .h files
For a link, it's the same like I've posted

:D

I think it will be possible to use this module. I'll tell you more after I get acquainted with this construction. :roll:

God bless you _kaktus_ . I've study around Marlin and it's *.h files. There is a file called pins_GT2560_V3.0.h where are plotted the pins for the board. We could change name according the necessary. After we'll must take an clamp for gray stripe, salding on pbc, take the pins we have replot and wire they with tft. What do you think about?

Hi.
:P

Well, so yes:
  • Buying a similar adapter will make it easier to connect a new display.

    For example, search on ebay under the phrase: "40Pin 0.5mm FFC FPC to 40P DIP 2.54mm PCB Converter Board".
  • Ingerance into firmware code.
    This is already a more difficult task,
    It requires
    1. the preparation of appropriate pin configuration,
    2. starting the SPI bus software,
    3. creating a communication code with the controller of the selected display.
It may be possible to use a ready-to-use library to operate the display.
