Thank you for your guidance here David, and all the related MCUFRIEND work over on GutHub, much appreciated! ---

Hello! I´m having the white screen problem with my TFT Touch screen too... 😕 I´ve tried to solve the problem like you said but i can´t! This is the link of the product! > **[Display LCD TFT 2.4" Touchscreen Shield para Arduino](https://www.electrofun.pt/arduino/display-lcd-touchscreen-shield-arduino)** > > Se está a procura de um Display LCD para fazer uma interface gráfica com o seu Arduino, encontrou o que precisava. ---

Thanks for the link. It shows a red shield with yellow header pins and an AMS1117 regulator U1. The text says that it has an ILI9341 controller. Please confirm whether the photos of the pcb are accurate. Please confirm the ID that is reported on the Serial Terminal e.g. from graphictest\_kbv or diagnose\_TFT\_support Follow the instructions in #18 Make notes on paper. Please type from paper notes to your message. Please copy-paste any messages from the Serial Terminal. (Click on the Terminal Screen. Press ctl-A ctl-C to copy. Press ctl-V to paste to your message.) David. ---

I have the product in front of me and it is the same but this my first time ever using an Arduino.... 😕 I´ve followed the instructions but the controller ILI9341 doesn´t even appear on the document... ---

Comparing the pcb photos there are some differences... ---

You do not need to understand technical things. Just describe the difference(s) between the pcb and the photos on the link e.g. 1. colour of header pins. Yellow or Black? 2. presence of regulator U1. Yes or No? Do you know how to run the Serial Terminal? Click the icon at the top-right of your Sketch window. Set to 9600 baud. Do you know how to install Libraries? Everyone has to start with Arduino. There are a lot of things to learn. Many are intuitive if you are familiar with a PC. If English is not your first language, use Google to translate. David. ---

1- The header pins are yellow 2 - Yes the only difference is that there are not those two small components called C1 and C2 (as you can see in the link photo) and the other "components" are in slightly diffrent positions... I don´t think so... 😕 i can´t find the option to change that to 9600 baud. ( i´m using IDE on Windows). Yes i think so but it´s better if you tell me the right way to install them so i can confirm please. thanks for all the help you´re providing! ---

ok the libraries are ready and I downloaded the touch screen library from the internet and then I used the function: add zip library. When I ran the diagnostic\_TFT\_suport and opened the Terminal Serial appeared this: Diagnose whether this controller is supported There are FAQs in extras/mcufriend\_how\_to.txt tft.readID() finds: ID = 0x0 MCUFRIEND\_kbv version: 2.9.8 This ID is not supported look up ID in extras/mcufriend\_how\_to.txt you may need to edit MCUFRIEND\_kbv.cpp to enable support for this ID e.g. #define SUPPORT\_8347D New controllers appear on Ebay often If your ID is not supported run LCD\_ID\_readreg.ino from examples/ Copy-Paste the output from the Serial Terminal to a message in Displays topic on Arduino Forum or to Issues on GitHub Note that OPEN-SMART boards have diff pinout Edit the pin defines in LCD\_ID\_readreg to match Edit mcufiend\_shield.h for USE\_SPECIAL Edit mcufiend\_special.h for USE\_OPENSMART\_SHIELD\_PINOUT ---

Please do not install from ZIP. The Library Manager is much better. I found [Adafruit Touchscreen](https://github.com/adafruit/Adafruit_TouchScreen) from the Library Manager. It will install with a click from the Manager. (you do not need to visit Github) You can run the LCD\_ID\_readreg sketch. I _might_ be able to help. David. ---

That looks BROKEN to me. You can try forcing the ID e.g. edit setup() function in graphictest\_kbv.ino ```cpp void setup(void) {     Serial.begin(9600);     uint32_t when = millis();     //    while (!Serial) ;  //hangs a Leonardo until you connect a Serial     if (!Serial) delay(5000);          //allow some time for Leonardo     Serial.println("Serial took " + String((millis() - when)) + "ms to start");     //    tft.reset();                //hardware reset     uint16_t ID = tft.readID(); //     Serial.print("ID = 0x");     Serial.println(ID, HEX);     if (ID == 0xD3D3) ID = 0x9481; // write-only shield //    ID = 0x9329;                            // force ID     tft.begin(ID); } ``` change the "force ID" line to 0x9320 or 0x9329 e.g. ```cpp     ID = 0x9329;                            // force ID ``` David. ---

Do I need to execute that code? i´ve executed the graphictest\_kbv and the result in the Serial Terminal was: Serial took 0ms to start ID = 0x0 (i´m using the COM8 door) ---

You have "graphictest\_kbv.ino" in your IDE "edit window" Find the setup() function. It is near line #85. You just need to delete the two slash characters `//` at the left of line #96 Then click the [Upload] icon (second from left) It will still report ID = 0x0 to the Serial Terminal. But the TFT _might_ work with ID=0x9320 or with ID=0x9329 David. ---
