Ive not had my TFT long, and was tearing my hair out, all working now, thank you.
you sir. saved me soooo much, was making a present for my girlfriend was getting too close for comfort!!Thank You!!!
Are there any other identifiers? I've tried using all of them, still white screen. I would appreciate if you could take some time and help me out.
If anyone is having problems with not being able to find the port or connecting to the board I highly recommend getting a new cable, I didn't think it would be a problem to do with the cable since it was making the screen go white, but it was and its all working perfectly fine with a new cable!
Kudos to you DPV Tech, I spent a few hours looking to resolve the white screen issue, mucking around with install of libraries and so on, your tutorial fixed my issue immediately! Awesome, thank you...
Could you please help me out. I could not find the right identifier. I've tried all of them
I am using 3.5 TFT display
And I am get
Unknown lcd driver chip : 0
Pls help me
same with me
Just connect the RESET pin of the display to the RST pin of the Arduino. This fixes a proper reset at power up.
Yes exactly correct!
I have been trying to use software reset command at the beginning of my code.
It didn’t work... white screen all the time!
As soon as I arrange hardware reset the display started working !
The only disappointing thing here is that u have to use a pin on microcontroller for just that purpose which is stupid loss...
hi mate, i did change the identifier the screen work but i have inverted screen i need to read from right to left and some letters are upset down can u help ?
I just received a 2.4 inch display and tried to get it going on the Uno. There's not much on the board to identify it but it is a Mcufriend display. It simply had printed on the back of the board "www.mucfriend.com" "tftlcd for arduino uno (spiflash). Running graphictest gives blank screen, serial port output reports:
Serial took 0ms to start
ID = 0xC0C0
That's it and the screen stays white. Is there some configuration I have to do or is this screen not supported? Any help greatly appreciated.
the prolem white screen of mine is with esp32, so the solution is the same?
Thank you sir, I couldn't make without your help!
It worked!
Setting the identifier manually hasn't fixed the white screen problem in my case.
When I don't change anything, the ID shows up as "0"...
set it to 0x9341

謝謝教導我測試成功了，抱歉我以為她會跑else if(identifier == 0x9341) {}原來要一個個測試，等等我把他轉二進制，測試看看會不會跑if
When I use the 9325 and 9328 I get color and movement but not the correct display. Mostly full pink screen turning to blue back to pink. Should I try other Identifiers? The seller just sent me a folder which contained this file _9341uno. When I try it I get an error: a sub folder of your sketchbook is not a valid library .Does that mean they think it is ID 9341? This was the Zip file they sent 2.4inch_Arduino_ILI9341_V2.0
What if the screen shows what it's supposed to when you press the reset button but stays white any other time?
Sir i'm using Arduino Mega 2560 with 1.8 TFT st7735 the code is compiling but showing a white screen on TFT. After checking the serial monitor it is displaying present time.
Hi, I want to use the TFT screen just as a monitor in my PC case (for displaying temperature information and stuff)
How can i proceed as long as I dont have "arduino" file to copy the file in ??
thank you :(
Thanks very much, this worked and I managed to get my display working :-)
Unfortunately I then removed the protective cover and discovered the screen is cracked Doh!
This is the only video that helped me. Thanks
PLS friend! Can you send me full instruction How to sorve that problem TFT LCD ILI 9488 Shield with Arduino Mega 2560 thank you
Thx for the video.Great fix.You´ve got a new subscriber.
its work for me think you so much i try it with 0x9341 and its work for me
hello. sorry for my bad English .I am trying to resolve my white screen problem. I have try all library whithout solution. now i think that it's about my register and i upload LCD_ID redreg library to show a different values of my registers and i found this:Unknow LCD driver C0C0. i am using a 2.4 TFT SPI 240x320 whith arduino uno. I need help.
Thank you for your comment..Try to replace your driver instead of the driver given in the program.But I did not check that. If it will not work, please try with the following--
www.instructables.com/id/How-to-use-24-inch-TFT-LCD-SPFD5408-with-Arduino-U/
The problem with these displays is the reset. The software reset in the driver on pin A4 doesn't work. Connect it to the Arduino RESET and it all works as expected. No need to manually configure the identifier!!! Sort out the root cause of the problem, not workaround it!
Hello, can you tell me how to do the wiring of tft screen with an arduino nano ?
Still didn't work for me. Maybe my screen is dead. It's white but none of the hex numbers work. Also, it doesn't seem to recognize any driver chip like in your video. You got "6809". All I get is "0".
TFT LCD test
Using Adafruit 2.8" TFT Arduino Shield Pinout
TFT size is 240x320
Unknown LCD driver chip: 0
Sorry for that. It works for most of the cases. But you try in google. You may get different methods. If it is white, it may not be dead. Most of the cases, we get the hex code as given by Adafruit Industry. But most of the boards come from China and they use different Drivers and therefor this white screen problem occurs.
If you woun't get any solution, then buy boards from Adafruit directly from there website(I am not advertising their brand), it will be little costly, but you will not get any problem.
You can visit to our "dpvtechnology"website for other components (till now,it is only for india).
Thanks for the help DPV TECHNOLOGY. After some searching around google, it seems like there are numerous versions of this display that all look almost identical but have different driver chips. Therefore, no one solution will work for them all. You have to try multiple different methods. I think you're right -- if the screen is white, it's probably a sketch and/or library issue and not a hardware issue.
My advice to anyone else having the white screen problem -- try the steps in DPV TECHNOLOGY's video and if that doesn't work, keep trying other methods until you find one that works. Google can help find the other methods.
@@Samuel-km5yf Did you find it?
Hello,
I'll use it for an operating system for a cellphone but i can't manage it.Help me plz
Thanks for the video it finally worked!
It finally worked!
Many thanks, I finally got may LCD to work. :)
hello DPV TECHNOLOGY.i have used all things that you showed on your video but my white screen problem hav'nt changed
Der Jean François Houssou ,in most of the cases,the given method works fine.But if the driver configuration is not similar to the given driver,it will not work.For that it is difficult to solve the problem.try to google to fix in your case.If you find any solution for your case,please upload a video so that other people also get benefited.Thank you.
If u r using mcufrind shield then download mcufriend tft libraries & try the examples if u still get white screen then go to this link forum.arduino.cc/index.php?topic=450176.0
Try the MCUFRIEND_kbv-master Library then uncomment your particular tft screen in MCUFRIEND_kbv.cpp
@@johndripper I am having similar issues, white screen, I added the kvb libraries, graphicstest reports 0XC0C0 as identifier, and I don't know where to go from here. BTW I don't see a link in your reply.

Thanks man! Super helpful!
Hello, i found my ID is 0x9481 from the seller because i didn't find it ont the code, i put it in the same place as you did, but the screen steel white!! nothing appears!!
Very helpful. It worked thanks!
You are welcome .
thank you very much! it worked!
Oh nice it works! Mine is 0x7575.
Thanks
that worked perfectly. Thank you.
I have tried all the identifiers but my TFT is not working , kindly tell what to do now
If this method is not working, then please contact the seller to know the identifier or you google it to find another method..We don't have other methods to do find out the identifier .Thank you
