Basic code to make Arduino communicate with ILI Colorful, bitdifferent shades4-wire resistive touchscreen8 bit digital interface, plus 4 control lines. CS chip select to A3. ILI is integrated inside the display. It drives the display and has nothing to do with touchscreen Although the shield connects some pins of ILI together with pins of the touchscreen.

To read a byte from ILI after sending a read command e. Then command 0x2Ch. Then send in sequence for every single pixel in the area a value of the color to display. The color has 2 byte format. The touch screen is attached on the surface of the display. So you can't write to LCD display and read the touch screen in the same time. Wikipedia: Touch-screen devices using resistive technology, a two-dimensional membrane potentiometer provides x and y coordinates.

The top layer is thin glass spaced close to a neighboring inner layer. The underside of the top layer has a transparent conductive coating; the surface of the layer beneath it has a transparent resistive coating.

A finger or stylus deforms the glass to contact the underlying layer. Edges of the resistive layer have conductive contacts. Locating the contact point is done by applying a voltage to opposite edges, leaving the other two edges temporarily unconnected. The voltage of the top layer provides one coordinate. Disconnecting those two edges, and applying voltage to the other two, formerly unconnected, provides the other coordinate.

Alternating rapidly between pairs of edges provides frequent position updates. An analog-to digital converter provides output data. First we need to detect if there is a touch. Then we need to read a position of a touch. Touchscreen I tested sometimes wrongly detects a touch, outside of the touched point.

To prevent this I added some delays and the X and Y analog value is read repeatedly and touch is approved only if values do not differ a lot. Log in Sign up. Beginner Protip 1 hour 66, Things used in this project.

This module works with 3. The ILI TFT display board which is shown in the circuit diagram above has 14 pins, the first 9 pins are for the display and the other 5 pins are for the touch module. MOSI: master-out slave-in. SDI: serial data in. MISO: master-in slave-out. SDO: serial data out. The display module is supplied with 5V that comes from the Arduino board. This module has a built-in 3. To connect the Arduino to the display module, I used voltage divider for each line which means there are 5 voltage dividers.

Each voltage divider consists of 2. The second library is Adafruit graphics library which can be installed also from Arduino IDE library manager. ZIP Library … and browse for the. The same thing for the second file. The previous 2 libraries are included in the main code as shown below :. And this one shows Proteus simulation not perfect result! Proteus simulation file download link is below, use version 8.

I am trying to confirm that but wonder is you know the answer to this. The shield version works fine and must have logic level converters built in. Thanks, Jack. Here is the backside of my ILI I think the J1 solderable link allows the ILI display to be powered from a 3.

I have a 2. Im using that with an Arduino uno to make an interface to set certain parameters for my project through the LCD. My program will have different menus.

I have some functions written already. They are only supposed to make the screen layout on the basis of the button pressed.

Is there a way to clear the screen using the Adafruit libraries? I know there is a function to do so using the UTFT library but that does not seem to work with the shield I have.

Im a newbie so I dont know much about the connections.

I only figured that out using the examples given in the libraries. The screen works fine for the first menu but when I press the button, it turns white. Any help would be appreciated. Please say exactly what board, Touch controller etc. The website says there are several versions. Explain what you expected. And what you actually got. The example codes with the touch screen work fine and they use the same libraries.

Whenever i run my code, everything works fine till the first page which only has one button. When the button is pressed, it is supposed to draw another page. In my code, i change the screen to blue color and try to print some text. If i only have tft. And if i have the code as it is with the text, i get a white screen. There is nothing to clear the screen in the libraries I am using.

Could that be the problem? Touchscreen and TFT share the same pins. That fixed the problem I was stuck on for a couple of days now. Thanks a lot!

It is a big, low-cost touch display which is very easy to use. Hello guys, I am Nick and welcome to educ8s. If you are new here, welcome, be sure to subscribe and check the previous videos on the channel. Today we are going to learn how to drive the 2. Compared to one of my favorites displays, the 1. The screen also offers touch functionality which is an added bonus and an SD card slot at the back.

It uses the SPI interface, so the connection with the Arduino is very straightforward. Full disclosure: All of the links above are affiliate links.

Thank you for your support! Another thing I like about this display is that it does not come as a shield like the touch display we were using so far. This is very important because we now have a low-cost display that we can use with every board. The first 9 pins of the display are the power pins and the SPI pins. So, if we connect only the first 9 pins of the display, we can use it as a regular display without touch functionality. The display uses 3. So, we need to use some 10K resistors if we want to drive it with a board that uses 5V logic levels like the Arduino Uno.

Arduino and the 2. But as you can see it is very slow in updating the screen. It takes many seconds to update the whole screen which is a pity. It can display text with more speed though. It is obvious that the Arduino Uno is not enough to drive a display with such a high resolution. It is obvious that we need a more powerful board to drive this display effectively.
