Arduino Uno shield UTFTGLUE example 480x320

Please post a link to the actual display that you have bought. e.g. Ebay sale page.

It looks like an 18x2 header. So it is probably a Shield designed for a Mega2560. From extras/mcufriend_how_to.txt:

17. If you do not have a standard Uno Shield, you can add a SPECIAL to the mcufriend_special.h
    Edit mcufriend_shield.h:  #define USE_SPECIAL
    Edit mcufriend_special.h: e.g. #define USE_MEGA_16BIT_SHIELD
    If your "special" is write-only,  the library can not read the ID.  It always returns 0xD3D3

Mega2560 Shields are almost always read-only. So you need to force the correct ID e.g. tft.begin(0x9488);

Please try regular example sketches. (with correct ID) Only try UTFTGLUE when you have regular sketches working. Edit UTFTGLUE.h to set the default ID to 0x9488

@prenticedavid I was try regular example sketch Glue_Demo_480x360 I've added #define USE_SPECIAL to mcufriend_shield.h and edit UTFTGLUE.h like this

    void InitLCD(byte orientation=LANDSCAPE) {
        MCUFRIEND_kbv::reset();
//      uint16_t ID = MCUFRIEND_kbv::readID();
//       if (ID == 0) ID = 0x9341;        //DealExtreme with EXTC=0
//       if (ID == 0x8989) ID = 0x1289;
//       if (ID == 0xD3D3) ID = 0x9481;   //write-only controller
//       if (ID == 0xD3D3) ID = 0x9486;   //write-only controller
//       if (ID == 0xD3D3) ID = 0x9090;   //write-only controller HX8357-D
//       if (ID == 0x9327 && orientation == LANDSCAPE) orientation = 3;
        MCUFRIEND_kbv::begin(0x9488);
        MCUFRIEND_kbv::setRotation(_orient = orientation);
        _radius = 4;
    }

Same result but the white area now changes to black, This is a description of the product i bought Features Support Arduino Mega2560 Directly inserted OnBorad level conversion chip for 5V/3.3V MCU Compatible with 3.3/5V operation voltage level Compatible with Arduino-Series development Board Compatible with UTFT / UTFT_Buttons /Utouch Library for arduino Provided 12-examples with Arduino ,3-examples with STM32?

Please provide a link. You might not find the actual shop that you bought from. But you can probably find the identical item on Ebay, AliExpress, ... and post a link to that item.

Your text description does not make sense. It is much better if I can see a photo of the pcb from the Ebay link.

https://www.ebay.com/itm/174508022307 https://a.aliexpress.com/_mtpoEqB similar but not the same sorry, can't find on ebay or aliexpress

Here the picture of the pcb lcd i've bought,,

My apologies. Your photo in #0 was difficult to see. I thought that I saw 18x2 header pins on the display shield. On reflection it was probably the 18x2 header socket on the Mega2560.

Anyway, your new photos show a regular Blue 3.5 inch Uno Shield. Please do not dismantle Shields. I only needed to see the top photo.

You don't need any "USE_SPECIAL". Just install MCUFRIEND_kbv via the IDE Library Manager. Plug in the Shield. Run all of the examples. Every example should run 100% out of the box.

If you have a problem with any of the examples, quote example name and copy-paste the output from the Serial Terminal.

If you have installed via ZIP or altered any library files I strongly advise you to delete the folder. Then install a fresh copy via the IDE Library Manager.

If you are experienced with Git we can do things differently. Otherwise it is best to use Arduino IDE tools.

i was delete all library then clone library directly from github but the result is same, i was try graphictest_kbv.ino

[prenticedavid]

If you follow my advice we can get you going within minutes.

[fajarnurprasetyo]

@prenticedavid ok, how..

It does not matter whether the Arduino IDE is running on Linux, Mac or Windows. There is always a Serial Terminal. And you can always copy-paste.

[prenticedavid]

How is the copy-paste doing ?

You can always type the text manually. But copy-paste is MUCH safer.

I haven't tried it yet. I will try tomorrow, still busy with my work.
