Touch problem [SOLVED]

[Tomasz Pacak]

Hello again. I'm trying to find a solution to the problem and it turns out that LCD and touch are smooth. Only the LCD is rotated by 180 degrees. Is there some way to display everything "upside down" on the LCD?

[Fernando Garcia]

Hi!

You can show some picture?

Best regards.

[Tomasz Pacak]

Match show where I press to enter setup "DATE & TIME". If it was impossible to rotate the screen the problem would be solved. The arrow shows the direction of rotation of the screen.

[Fernando Garcia]

I can't see any problem.

To change the position use a flat cable.

Tell us what you did to solve the problem.

[Tomasz Pacak]

Fernando tell me how do I connect a flat cable and what, if touch is glued to the LCD.

[Fernando Garcia]

Hi!

I'm sorry was a misunderstanding.

The one way to solve it is changing the calibration.

Best regards.

[Tomasz Pacak]

You have an idea how to change the calibration?

[Fernando Garcia]

No, maybe Henning Karlsen can help.

Finally was a problem making screens. I bought another and I will perfect.

[Tomasz Pacak]

I found the solution to my problem I wrote to ITEAD Studio and spreading my configuration to Touch. LCD and Touch To work properly enough:
in the configuration file library UTouchCD.h put the new configuration code

Code: Select all

#define CAL_X 0x00430ED8UL
#define CAL_Y 0x002A0EECUL
#define CAL_S 0x000EF18FUL


and then in the code file FERDUINO in file ProcessMyTouch change the code:

Code: Select all

x=myTouch.getX ();
y=myTouch.getY ();



on

Code: Select all

x = 399-myTouch.getX ();
y = 239-myTouch.getY ();


Everything works as it should

Hello Everybody.

I'm facing a similar problem, i cant even make the touch work.

I'm new here, and i got a problem that probably will be in futher also a problem for someone maybe.

I just bought a TFT http://www.ebay.com/itm/111114349519 400x240 as recommended and seems the LCD its working fine, just the calibrate its a lil hard to do.

I dont know what more can be done, but i believe its impossible to calibrate it, since i cannot sucess to do it.

Someone faced it before or know another way to calibrate?

I'm also tryng with lastest URtouch and UTFT to find a way to calibrate, no sucess...

Thank you.

Hi!

Welcome Michael!


If the touch doesn't work can be problem with TFT, TFT shield or code.

Make sure that your code is like this for TFT shield from Itead.

Code: Select all

UTouch      myTouch(6,5,4,3,2);

Double check the soldering of your shield.

If needed send an email to Coldtears to ask for help.

Best regards.

Hi!

Welcome Gkourtzoglou!

Have you contacted the seller to ask for help?

Have you checked all soldering of your TFT shield?

Best regards.

[Gkourtzoglou Kostas]

the touch screen play with calibration code

[Fernando Garcia]

But if the coordinates are wrong can be bad contact or touch screen with problem.

Don't forget to try with orientation as LANDSCAPE and PORTRAIT in calibration code.

Also check the coordinates here: http://rinkydinkelectronics.com/t_cal_verify.php
