Well I have a 3.5" TFT touch shield working with my uno which works really well its identifier is "ILI9488", so far having a ball playing with it, I can draw with it and place text and use the touch screen, its great fun.

I do have one issue though and that is solid colours the are all striped, and red is NOT red same for other colours. I can"t find on the internet where anyone else has had this issue.

I have attached a pic, basically there are supposed to be 6 different colours across the top of the screen but I get these strippy blocks of not the right colour.

my script uses two libraries Adafruit_GFX.h and MCUFRIEND_kbv.h , but I had another working example that uses UTFTGLUE.h instead of MCUFRIEND_kbv.h , both display the same behaviour with solid shapes ie fillRect looks like a zebra skin BUT in the example that uses the UTFTGLUE.h there are some random lines drawn and they are definitely RED lines even though in the same script the filled shapes are zebras.

Also, I am quite sure that I wired it right, since I did it according to the UTFT_Requirements.pdf in the library folder (with DB0 to DB7 tied to GND).

Now, I did some sniffing in the SSD1289 datasheet, link below, and found out that it requires, for 8-bit mode, a certain combination of pins PS3, PS2 and PS1 (eg. if PS3 = 1, PS2 = 0, PS1 = 1, PS0 = 0 than it is in 6080 8-bit mode). However, these pins are not on the breakout of the LCD.

I have bought this 3.5" TFT LCD from ebay, and I can"t get it to work no matter what I do, what library I use or what tutorial I follow ... All I have is white screen shining brightly and that"s it (mind the attached pictures). It supposedly uses one of these controllers: ili9481, ili9468, ili9488, hx8357 or r61581.

I only saw the first attempts with a skewed Tiger. I have just seen Figure2.bmp and it does show your actual TFT screen displaying a Tiger with inverted colours.

I have worked around my issue with the display in a fashion that I didn"t think possible with my lack of knowledge. So, the following is for people who experience the same problem or are just interested in the matter (conclusion at the bottom):

After searching for many, many different ways of describing my problem on Google, I came across this page on the Arduino forums of someone who had a completely different issue. However, Google found some text embedded in some code posted on that particular page (1.8" 128x160 SPI TFT LCD Display white screen - Displays - Arduino Forum), which had nothing to do with that problem, but was helpful for me:

Now I don"t have this particular display, but the description of the problem showed similarities to mine. And there was some sort of solution there as well. However, being the n00b I am, I understood next to nothing. I did give me the insight though, that I should try to make a workaround within the libraries that I will use in my programs. This way, I don"t have to add extra code within the programs to shift the dimensions, and I can also download other programs and run them just fine with my altered libraries.

However, this solution would mean constantly accounting for a weird resolution which would make developing programs much more difficult than needed, since I would have to constantly remind myself of that odd resolution. Plus, there would always be extra columns and rows that recieved some computing, which would limit the speed of the Arduino. So I looked further in the libraries to find the place where the (0,0)-coordinates were defined.

The problem wasn"t actually a problem within the files, so I suspect that there is indeed an alignment issue with my display. But I found the code within it, which I changed so that the starting point of the drawing shifted. After looking through all the libraries within the TFT folder (meaning: the TFT library, AdafruitGFX library and Adafruit ST7735 library) and trying to understand as much as I could, I found the location: within the Adafruit_ST7735.cpp file, there is code of the "Adafruit_ST7735::commonInit(...)" function. This function defines the value of "colstart" and "rowstart" as 0. I changed it to correspond with my deviation.

After multiple hours of work, the description of the problem in the quote above seems very logical to me as how to solve it, but I like how I kind of figured it out by myself as well, knowing very little of programming languages.

A TFT display resolution can be configured within Adafruit_ST7735.cpp within the Gcmd[] array within the Adafruit_ST7735::writecommand(...) function. The other arrays in that function can also be configured, but TFT.cpp specifically states that a TFT display is configured according to the Gcmd[] array. I don"t remember if it is necessary, or if I just added the following because I changed, tried and errored so much, but I also added the corresponding values to the "_width" and "_height" within the TFT.cpp file.

The origin of a TFT display can be configured within Adafruit_ST7735.cpp within the "Adafruit_ST7735::commonInit(...)" function. Changing the values of "colstart" and "rowstart" will change the row and column of the origin. By standard, they are both defined as 0 (-> colstart = rowstart = 0;), but writing them as two different definitions makes it possible to set a virtual origin, relative to the misaligned origin of the display.

In this guide we’re going to show you how you can use the 1.8 TFT display with the Arduino. You’ll learn how to wire the display, write text, draw shapes and display images on the screen.

The 1.8 TFT is a colorful display with 128 x 160 color pixels. The display can load images from an SD card – it has an SD card slot at the back. The following figure shows the screen front and back view.

This module uses SPI communication – see the wiring below . To control the display we’ll use the TFT library, which is already included with Arduino IDE 1.0.5 and later.

The TFT display communicates with the Arduino via SPI communication, so you need to include the SPI library on your code. We also use the TFT library to write and draw on the display.

The 1.8 TFT display can load images from the SD card. To read from the SD card you use the SD library, already included in the Arduino IDE software. Follow the next steps to display an image on the display:

Note: some people find issues with this display when trying to read from the SD card. We don’t know why that happens. In fact, we tested a couple of times and it worked well, and then, when we were about to record to show you the final result, the display didn’t recognized the SD card anymore – we’re not sure if it’s a problem with the SD card holder that doesn’t establish a proper connection with the SD card. However, we are sure these instructions work, because we’ve tested them.

In this guide we’ve shown you how to use the 1.8 TFT display with the Arduino: display text, draw shapes and display images. You can easily add a nice visual interface to your projects using this display.
