Overview:The 3.2” inch TFT LCD module integrated a SSD1289 TFT LCD controller and ADS7843 compatible touch screen controller as well as a SD card cage. It is suitable for embedded systems which require display high quality colorful image or video with interactive control and storage purpose. The Module interfaces to micro-controllers via a 2*20 Pin 2.54mm dual row pin header interface , can easily be connected to any microcontroller or FPGA and DSPs.

3.2" TFT LCD Display is a LCD touch screen module. It has 40pins interface and SD card and Flash reader design. It is a powerful and multifunctional module for your project. The Screen include a controller SSD1289, it"s a support 8/16bit data interface , easy to drive by many MCU like STM32 ,AVR and 8051. It is designed with a touch controller in it . The touch IC is ADS7843 , and touch interface is included in the 40 pins. It is the version of product only with touch screen and touch controller.

The shield route all the LCD data pins to port PC1-PC8 and PC12-19, control pins to PD0-PD3, this design can acheive high speed data transfer (three cycles per write strobe to the LCD) to maximize LCD display speed. The SPI interface (for SD or flash control) is route to the ISP header of DUE, so that high speed SPI transfer with DMA can be achieved.

The 3.2 Inch 320×240 TFT LCD Touch Screen Module for Arduino features a 320×240 resistive touch panel with SD Card Socket, This Module can be easily connected to an Arduino Mega 2560 Board using the 3.2 Inch TFT LCD Adapter Shield.

Note: When connecting to Arduino Mega 2560 or compatible boards with 5V working voltage, it is require to use a logic level converter such as TFT LCD Adapter Shield

In this Arduino touch screen tutorial we will learn how to use TFT LCD Touch Screen with Arduino. You can watch the following video or read the written tutorial below.

For this tutorial I composed three examples. The first example is distance measurement using ultrasonic sensor. The output from the sensor, or the distance is printed on the screen and using the touch screen we can select the units, either centimeters or inches.

As an example I am using a 3.2” TFT Touch Screen in a combination with a TFT LCD Arduino Mega Shield. We need a shield because the TFT Touch screen works at 3.3V and the Arduino Mega outputs are 5 V. For the first example I have the HC-SR04 ultrasonic sensor, then for the second example an RGB LED with three resistors and a push button for the game example. Also I had to make a custom made pin header like this, by soldering pin headers and bend on of them so I could insert them in between the Arduino Board and the TFT Shield.

Here’s the circuit schematic. We will use the GND pin, the digital pins from 8 to 13, as well as the pin number 14. As the 5V pins are already used by the TFT Screen I will use the pin number 13 as VCC, by setting it right away high in the setup section of code.

I will use the UTFT and URTouch libraries made by Henning Karlsen. Here I would like to say thanks to him for the incredible work he has done. The libraries enable really easy use of the TFT Screens, and they work with many different TFT screens sizes, shields and controllers. You can download these libraries from his website, RinkyDinkElectronics.com and also find a lot of demo examples and detailed documentation of how to use them.

After we include the libraries we need to create UTFT and URTouch objects. The parameters of these objects depends on the model of the TFT Screen and Shield and these details can be also found in the documentation of the libraries.

So now I will explain how we can make the home screen of the program. With the setBackColor() function we need to set the background color of the text, black one in our case. Then we need to set the color to white, set the big font and using the print() function, we will print the string “Arduino TFT Tutorial” at the center of the screen and 10 pixels  down the Y – Axis of the screen. Next we will set the color to red and draw the red line below the text. After that we need to set the color back to white, and print the two other strings, “by HowToMechatronics.com” using the small font and “Select Example” using the big font.

Here’s that function which uses the ultrasonic sensor to calculate the distance and print the values with SevenSegNum font in green color, either in centimeters or inches. If you need more details how the ultrasonic sensor works you can check my particular tutorialfor that. Back in the loop section we can see what happens when we press the select unit buttons as well as the back button.

HY-TFT320 is a 3.2 inch TFT LCD Screen module, 320*240 (resolution), 65K color, 34pins interface , not just a LCD breakout, but include the Touch screen, SD card. So it’s a powerful extension module for your project.

This Screen includes a controller SSD1289, it’s 16bit data interface, easy to drive by many MCU like STM32 ,AVR and 8051.HY-TFT320 is designed with a touch controller in it . The touch IC is XPT2046 , and touch interface is included in the 34 pins breakout. Another useful extension in this module is the SD Card socket . It use the SPI mode to operate the SD card, the SPI interface include in the 40pins breakout.

The UTFT library is required to be installed to get this screen model display. This library is especially designed for 3.2” TFT LCD screen using 16 bit mode. The library require the following connections.

Note: The TFT controller model needs to be declared in the initializing statement. ITDB02 myGLCD(38,39,40,41) needs to be modified as myGLCD(38,39,40,41,ITDB32S) when using Arduino Mega2560.ITDB02 myGLCD(19,18,17,16,ITDB32S) needs to be commented when using Aduino UNO. Otherwise it just show a blank screen. In practice, RS, WR, CS, RSET can be connected to any free pin. But the pin number must be in accord with myGLCD(RS,WR,CS,RST).

The LCD has a 3.2" 4-wire resistive touch screen lying over it. The Touch libraryneeds to be installed to get it works. This library is designed for 2.4’’ TFT, 3.2” TFT LCD screen module.

The default setting is accurate for 2.4” TFT module, but you need to calibrate when using 3.2” TFT module. A program to calibrate the touch screen is included in the example. If you touch screen is inaccurate, you need to run touch_calibration. Follow the on-screen instruction to calibrate the touch screen. Better not use your finger to calibrate it, use your accessory touch pen to pressure the frontsight with stength. Then record the calibration parameters and apply them in ITDB02_Touch.cpp in your touch screen library.

There is built-in SD card slot in the shield, so we can use it to upload images. But the images need to be converted RAW format first. SD libraries tinyFAT and tinyFAT_16 need to be preinstalled for displaying the image.
