Topic: 7" TFT LCD Working with 320x240 (Read 88 times) previous topic - next topic


Hi folks,

Finally I could get my 7" TFT LCD working with Utft library.

But when I upload the library example "UTFT_Demo_800x480" it shows me only part of the screen, like the picture I attached.

it's a 800x480 screen but when I get touch values from X and Y, it gives me values from 0 to 320 and 0 - 240. Then it's impossible to calibrate this.

Any idea how to solve this?

it has a SSD1963 controller.


Your 7" diagonal looks a lot smaller than I would expect.

In fact it looks rather like regular 3.2" diagonal 240x320 display.

So you would run the 320x240_Demo from the examples.

I doubt if anyone would put a SSD1963 on a small display.



Sorry, it's a 5".

And yes. It has a SSD1963 controller, as you can see it.



Yes,  it looks like 5".  Definitely NOT 7".

What constructor() have you used?
Just copy-paste this line from your sketch.

The 800x480_Demo should work fine with a 5" SSD1963.




I just tried to upload the example from UTFT library.

I've attached my code.

Thank you

This is your constructor:
Code: [Select]

// Remember to change the model parameter to suit your display module!
UTFT myGLCD(TFT01_50,38,39,40,41);

Since UTFT.h says:
Code: [Select]

#define TFT01_50 13 // SSD1963 (16bit) 800x480

it looks as if everything should work correctly.

Which particular model of 40pin Adapter Shield are you using?
Mind you,   if you got this wrong, the display would not show anything at all.

Are you sure that it is 5" 800x480 and not a 4.3"
Code: [Select]
TFT01_43 12 // SSD1963 (16bit) 480x272

The obvious thing to do is draw a specific 480x272 rectangle.   And see where it displays.




Sorry, I measured and it's a 4.3". So sorry about my mistake.

I'll try to calibrate it now.

thank you so much
