Hi guys
Im trying to develop a code for using tactile of my screen Ili9481 https://fr.aliexpress.com/item/3-2-3-5-pouces-480-320-TFT-LCD-Module-cran-D-affichage-ILI9481-ILI9486-Contr/32917044135.html?spm=a2g0w.search0104.3.2.52c02ad1UADcRA&transAbTest=ae803_3&ws_ab_test=searchweb0_0%2Csearchweb201602_2_10065_10068_319_10892_317_10696_5735515_453_10084_454_10083_10618_431_10304_10307_10820_10821_537_10302_536_10843_10059_10884_5736015_10887_100031_321_322_10103_5736115-10892%2Csearchweb201603_56%2CppcSwitch_0&algo_pvid=e16d8564-a3b5-4410-849c-722ddd36fe99&algo_expid=e16d8564-a3b5-4410-849c-722ddd36fe99-0 on my Arduino mega 2560

But i dont have any result, my screen is only white, here is the code that i tried...

// This program is a quick demo of how to use the library.

// This program requires the UTFT library and a display
// module with at least 320x240 pixels resolution.
//
// It is assumed that the display module is connected to an
// appropriate shield or that you know how to change the pin
// numbers in the setup.
//

#include <UTouch.h>

// Teensy 3.x TFT Test Board : ,23,22, 3, 4

// Remember to change the model parameter to suit your display module!

Salut, c'est écrit dans la description que ce n'est pas un écran tactile..
