HELP !!! UK
Hi guys, complete newbie to Arduino but want to get into it, i recently bought an Arduino Mega 2560 and a 3.2 inch TFT LCD touch screen which is the WBYJB02, i can`t find any data sheets, info, pin diagrams or anything for this LCD.
I downloaded the UTFT Zip (UTFT - Rinky-Dink Electronics) which showed me a pin placement for the Arduino Mega and followed it to the letter and then ran the Arduino software, the backlight comes and the screen flickers every now and then but that`s all.
I tried to change the model parameters in the (Remember to change the model parameter to suit your display module!UTFT myGLCD(ITDB32S,38,39,40,41)
with every single one listed in the Keywords folder one by one, i let each one upload and waited to see if any of them would work, but non did, the LCD i have doesn`t appear to be in the list anywhere which is very frustrating.
Can anyone offer some help or advice please, i didnt get ashield` because i wanted to hard wire it myself to better understand how these things work.
Iv`e scoured the internet looking for the WBYJB02 LCD but apart from links to websites where you can buy one there are no actual data sheets or spec out there.
Thanks for your time.
The display is 3.3V only.
By the time that you have connected 21 level shifters, you are probably getting fed up.
It also looks as if there is a jumper selection for 8-bit or 16-bit. What is yours set for?
8-bit would save 8 level shifters.
Most Adapter Shields take a 40-pin male or possibly a 32-pin male. You appear to have a 32 pin female.
If you can find an adapter without the 32-pin header mounted, you could solder a 16x2 male strip.
There is no mention of which controller is used. After you have got your bi-directional level shifters sorted, you could read the controller ID. Then you would know which driver to use.

Hi David, thanks for your reply mate.
I understand not using a shield will make things more difficult but I need to keep things as slim as possible because I want to wall mount the LCD and connect it to the Mega via a long ribbon cable.
Due to a serious lack of data available for this LCD I'm struggling with connecting the LCD to my Mega arduino, even to do something as simple as just confirm the LCD works.
The processors on the WBYJB02 lcd are XPT2046 / 1525 which i believe runs the touch screen part of the lcd, the other main processor is 74HC573D / L1A2C7 - 02 / UnG1117G.
What i need help with is a wiring / pin diagram for the arduino mega 2560 R3 and a WBYJB02 Arduino Compatible 3.2 Inch Color TFT Touch LCD Screen Module if possible and hopefully the appropriate lcd driver to get the things to at least communicate with each other and do a demo so i know all the connections are correct, once that`s done i can move forward with my project.
Your help doing any of this would be very much appreciated mate so thank you for your time.
Cheers.
You have asked the same question in different threads. You must have 3.3V logic.
It is a lot easier to just buy a new display. Unless you can find a matching Adapter. What do the "spare" holes do?
