T-Deck plus - perfect working touch screen with LGFX/LVGL

[numnim2209]

Insert this piece of code:
// set interrupt mode uint8_t buf1[] = { 0x80, 0x4d, 0xb5 }; _writeBytes(buf1, 3); _freshConfig();

In the file:
/firmware/.pio/libdeps/t-deck/LovyanGFX/src/lgfx/v1/touch

at line 83:

Before build, change:
variants/t-deck/platformio.ini

[numnim2209]

The filename is:
Touch_GT911.cpp

newbie question, where is branch or folder for T Deck Plus to build, I was looking at tft-gui-work branch and environment: t-deck-tft upon building it says Error: src/main.cpp:118:10: fatal error: DeviceScreen.h: No such file or directory

@pagex I suggest you to follow the standard documentation: https://meshtastic.org/docs/development/firmware/build/ in case you still have issues please start a "new" discussion.

@numnim2209 what started your suggestion?

I did not try it yet but I have issues with the touch screen. Like laggy and not responding to long touch.
Are these the same?

And what this change will do?

As also @pagex is confused, on what branch / PR would this apply?

Thanks for the current suggestion, and in advance for your feed back!

When did you purchase that T-Deck Plus? I think only the first batch was affected that shipped in July/August. The newer ones shipped end of September had the fix described on LilyGo's issue page.

Hoi @numnim2209 I created a discussion here: #5606

It would be nice if you mention your changes there.

I agree that a double flash solution is not perfect, but on the other side you do not document your suggestion.

Before a brick my t-deck, I might ask for some background :)

I mention this there too, JIC.
