Hello All, I've just joined the forum!
I'm working on a project at the moment and I'm absolutely stumped! I am able to get the display to work perfectly but I can't get anything out of the touch screen.
I've bought a SainSmart 4.3" 480x272 TFT LCD Touch Screen Module which uses the SSD1963 controller, and also the SainSmart TFT Adaptor Shield to suit (it has "CTE TFT LCD/SD Shield" written on it), and also an Arduino Due - as a package. The link can be found here for reference to the product.
I've downloaded the UTFT and UTouch Libraries to go with this, as I've heard its the best option to use - the link can be found here for reference to these. I have followed the set-up instructions to the letter - installed the both of these libraries, found out which controller the display uses (SSD1963_480) and declared it in the set-up phase of the coding screenshot here. I know that when you first set up the library for UTFT, it's required that you edit the file "UTFT, hardware, ARM, HW_ARM_defines" and ensure that the correct shield has been selectedscreenshot here.
After doing all of this, I opened the demo sketch (from the UTFT examples folder) which runs through a few examples of how to display text, boxes, lines, etc; and this worked perfectly - but didn't require any input from the touch screen. I then proceeded to open the sketch (in the UTouch examples folder) to calibrate the touch screen, it appeared perfectly on the display and when I used a pen to calibrate it, it would respond to my input - so I presumed it was working perfectly.
As part of the set-up prodecure, it said in the documentation of the UTouch Library to modify the file "UTouch, UTouchCD" and edit the values that where given after you calibrated the screen - which I did screenshot here. Everything seemed to be going as expected, so I went on to try out the "UTouch_ButtonTest" sketch (in the examples folder) to see if everything had worked - but none of the buttons would register my input, no matter where I tapped the screen. I went over everything again to double-check myself, but it still wasn't working.
I decided to try the "UTouch_QuickDraw" sketch (in the examples folder) and again, it didn't matter where I tapped on the screen - nothing would work. I read a post that it's often necessary to use a external power supply on larger displays, so I gave this a try and still nothing. So I decided to edit one of these sketches to read out what the x and y dimensions where over serial, and they both showed as "-1" when I was prodding the screen.
I'm out of ideas and have searched everywhere on the web - but I can't find any answers. I'm hoping that someone can point me in the right direction and I'll be happy to provide any other info if needed. Thank you in advance.
The number of first posts on the forum from new users starting "I bought this from Sainsmart and it don't work" is not even amusing any more, but I can guarantee you won't be the last!
