LCDWIKI_touch Button

dino_t · November 22, 2022, 7:59pm

Dear Sirs,

Greetings!

First time I have tried SPI TFT LCD ILI9341... Plenty example codes tried none of them work on it apart from LCDWIKI Examples...Mostly all are working.But Touch Button example is not working,Just white screen observed.

Infact I need Touch Button functionality,unfortunately couldnt succeed.Moreover its Software SPI doesnt work ,had to connect all wires for hardware SPI, purpose of Pin saving failed too.

Uno is being used,Pin Numbers are changed accordingly.

Please Help me.

Thanks,

Regards,

*Set the pins to the correct ones for your development shield or breakout board.
*This demo use the BREAKOUT BOARD only and use these 8bit data lines to the LCD,

Your topic has been moved to a more suitable location on the forum. Installation and Troubleshooting is not for problems with (nor for advice on) your project.

dino_t · November 23, 2022, 5:14am

Thank You Sir.

dino_t · November 23, 2022, 3:40pm

Its been 28 hours eversince struggling.My TFT just supports only WIKILCD library. Unfortunately Its Touch Button example doesnt work on my tft.

If anyone has WIKILCD touch button code.Kindly help me with that code.

Resd old thread /discussion in this forum and implemented all instruction but still hopeless.

ZinggJM · November 23, 2022, 7:13pm

Maybe you would have a better chance if you post a link to where you bought your display.
And report what processor/board you use.

dino_t · November 23, 2022, 7:18pm

Locally Bought,ILI9341,XPT2046,2.4 Inch

dino_t · November 23, 2022, 7:21pm

I made some graphics and text display using WIKILCD Library.Other Library with their suitable hardware connection dint work.

Now problem is I need touch functinality as I have 2 Touch Button to call other functions

ZinggJM · November 24, 2022, 7:56am

There is a contradiction. Do you have ILI9341 or ILI9488?

ILI9488 is known to work with ILI9486_SPI, available with Library Manager.

Search for XPT2046 in Library Manager for a suitable driver class.

dino_t · November 24, 2022, 8:12am

I was trying to tell all that Code and Library is used.I have Changed according to ILI9341 and Use UNO Pin
LCDWIKI_KBV my_lcd(ILI9488,40,38,39,43,41) <-------- This For MEGA and ILI9488

dino_t · November 24, 2022, 8:14am

I have Tried XPT2046 Code example,codes are compiled without any error but LCD always remains White,no action at all.

dino_t · November 24, 2022, 8:41am

I wont use this TFT,Could you please give me name and type of TFT which supports UTFT or Adafruit library.Better if you can share photo of that TFT.

ZinggJM · November 24, 2022, 10:26am

No, I am not a TFT expert. I just tried to help you get started. Now that you have given more details, the real experts could step in. XPT2046 libraries are for use of the touch overlay. Their examples may be for a different TFT and/or TFT library.
