Bonjour, ceci est mon premier post e j'espere trouver de l'aide.
J'ai acheter un écran TFT sur aliexpress (Lien : https://fr.aliexpress.com/item/LCD-module-3-5-inch-TFT-LCD-screen-3-5-UNO-R3-REV3-MEGA328P-Board-for/32860538003.html?spm=a2g0w.search0104.3.85.333a1362zhjisN&ws_ab_test=searchweb0_0,searchweb201602_5_10152_10065_10151_10344_10068_5723115_5722815_10342_10343_10340_5722915_10341_5722615_10696_10084_10083_10618_10305_10304_10307_10820_10306_10821_10302_5722715_10843_10059_100031_10103_10624_10623_10622_5722515_10621_10620,searchweb201603_50,ppcSwitch_5&algo_expid=d2cc4386-1b12-4638-925a-460be97391a2-12&algo_pvid=d2cc4386-1b12-4638-925a-460be97391a2&priceBeautifyAB=0)
mais quand j'essaye de l'allumer il reste blanc !

J'ai pourtant chercher et j'ai télécharger les librairies Adafruit_GFX et Adafruit_touchscreen en suivant les branchement.

J'espere que vous pourez m'aider

Hello, this is my first post and I hope to find some help.
I buy a TFT screen on aliexpress (Link: https://www.aliexpress.com/item/LCD-module-3-5-inch-TFT-LCD-screen-3-5-UNO-R3-REV3- MEGA328P-Board-for / 32860538003.html? spm = & a2g0w.search0104.3.85.333a1362zhjisN ws_ab_test = searchweb0_0, searchweb201602_5_10152_10065_10151_10344_10068_5723115_5722815_10342_10343_10340_5722915_10341_5722615_10696_10084_10083_10618_10305_10304_10307_10820_10306_10821_10302_5722715_10843_10059_100031_10103_10624_10623_10622_5722515_10621_10620, searchweb201603_50, ppcSwitch_5 & algo_expid = d2cc4386-1b12-4638-925a-460be97391a2-12 & algo_pvid = d2cc4386-1b12-4638-925a-460be97391a2 & priceBeautifyAB = 0)
but when I try to light it, it stays white!

However, I searched for and I downloaded the Adafruit_GFX and Adafruit_touchscreen libraries by following the connections.

I hope you can help me
Install/Upgrade MCUFRIEND_kbv library via Library Manager.   Also Adafruit_GFX library.

If you have an old hacked version of the library,   delete that library.   Install correct version via Library Manager.



Thank you David! my screen is finally working! (escuse for my english)
