TFT LCD module has always been one of the hot products in DIY industry and LCD is basically the necessary products during all projects, at the same time, serial port modules are also the popular ones, because it takes few IO and the usage is simple. This section of the 2.4S-inch TFT LCD serial SPI integrated features of compact, SPI interface.
This is our 2.4 inch TFT LCD Display for Arduino Uno that will spice up your Arduino project with a touchscreen display shield with built in microSD connection. This TFT display is 2.4″ diagonal with 4 white-LED backlight and 240×320 pixels. It has way more resolution than a black and white 128×64 display. As a bonus, this display has a resistive touchscreen attached to it already, so you can detect finger presses anywhere on the screen.
There are many tutorials on Arduino shields for 2.4 inch TFT LCD displays. In this road test I apply different tutorials to check the performance and issues of this specific shield: AZ-Delivery 2.4 inch TFT LCD display with resistive 4-wire touchscreen and an integrated SD card reader.AZ-Delivery 2.4 inch TFT LCD display.
TFT LCD is a variant of a liquid-crystal display (LCD) that uses thin-film-transistor (TFT) technology. That improves image quality, better contrast and addressability.
Depends on the needs of your project. Arduino UNO processor frequency is low. With the Arduino UNO full-color TFT LCDs are suitable to display simple data and commands. The TFT controller used cannot switch internal display RAM, so you can"t use the double buffer technique for animations but still you can only re-draw small sections of screen.
Given the limitations of the Arduino UNO the bigger the display the worse the performance. The size of this display is adequate to meet that compromise between number of pixels, display area and capabilities of the Arduino UNO.
This module consumes most of the resources available in Arduino UNO. This is not a limitation of the module itself. In return, using a parallel interface allows you to quickly update the image. If you want to take advantage of all its functionality (LCD + touch screen + SD card), only pins 0 and 1 (RX and TX, respectively) and pin 19 (A5) remain unused. If the SD card is not used, pins 10, 11, 12 and 13 are additionally available. With a suitable layout, some SPI devices could be connected even if the SD card is used.
The PCB silkscreen indicates the main function of each pin, the labels are easy to read, although it does not show labels for the touch screen pins:Pin 9 - Touch X+ / LCD_D1
The SD card reader is very well located between the USB connector and the power connector, it does not touch either of them as it happens in other lcd tft shield modules and it is easily accessible to insert and remove the SD cards.
You can directly use the shield with any arduino uno. In this case we are using an Arduino UNO that exposes all the pins both on the header and on the board. In such a way that you do not need another shield to access the pins not used by the screen
ShieldCompatible with Arduino. 5V compatible, can be used with 3.3V or 5V logic. On-board 3.3 V (300mA LDO controller). The design is very well thought out and fits Arduino UNO perfectly.
2x74LVC245A Octal Bus Transceiver With 3-State outputs. This octal bus transceiver is designed for 1.65-V to 3.6-V VCC operation. The LVC245A is designed for asynchronous communication between data buses. The device transmits data from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the direction-control (DIR) input. The output-enable (OE) input can be used to disable the device so the buses effectively are isolated. Inputs can be driven from either 3.3-V or 5-V devices. This feature allows the use of this device as a translator in a mixed 3.3-V/5-V system environment. This chip solves the problem of how to interface 3.3V logic devices to a 5.0V logic chip such as the Arduino. Most 3.3V devices do not like being run with 5V signals and can be damaged or flaky. The 74LVC245 is designed so that even when it runs at 1.8V, it still happily accepts 5V signals in one pin and converts it to a lower logic level on the opposite pin. It has 8 pipes it can convert but it won"t work with bi-directional/pull-up based devices such as I2C or 1-Wire. It does work great for SPI, Serial, Parallel bus, and other logic interfaces.
If you want to take advantage of all its functionality (LCD + touch screen + SD card), only pins 0 and 1 (RX and TX, respectively) and pin 19 (A5) remain unused.

The ILI9341 which can control each pixel with a small number of pins. The shield connects ILI9341"s data pins 0-7 to Arduino digital pins 2-8 (allowing parallel communication, not SPI). ILI"s RESET goes to pin to Arduino analog pin A4.CS (chip select) to A3. RS (CD command/data) to A2. WR and RD to A1 and A0.
Includes a resistive 4-wire touchscreen (touchpad). The touch screen is attached on the surface of the display. Touch screen needs two analog inputs and two digital outputs. It connects through 4 wires, which share arduino pins 8, 9, A2, A3 with the ILI9341 driver. So you can"t write to LCD display and read the touch screen in the same time. I. Driver chip is XPT2046.
The resistive touch screen does not appear to appreciably affect the optical characteristics. Works properly, It takes a little pressure with the stylus for it to respond like in old mobile phones. You notice how it sinks into the screen when you press with the stylus. The stylus that comes with the module makes it easy to use if your interface design uses small controls. Some touch screen libraries offer better accuracy by specifying the resistance of the touch screen in the X direction. Resistance can be easily measured with a multimeter by connecting the test leads to the LCD_D1 - X + and LCD_DS X- terminals. Touch is sensitive to pressure.
This module is designed to plug directly into Arduino UNO R3 (or its clone) boards. It is compatible with CH340 and Atmega16u2 version boards, as well as Mega 2560. This LCD shield may also work with other boards, but the compatibility can"t be guaranteed.
In electronics world today, Arduino is an open-source hardware and software company, project and user community that designs and manufactures single-board microcontrollers and microcontroller kits for building digital devices. Arduino board designs use a variety of microprocessors and controllers. The boards are equipped with sets of digital and analog input/output (I/O) pins that may be interfaced to various expansion boards (‘shields’) or breadboards (for prototyping) and other circuits.
The boards feature serial communications interfaces, including Universal Serial Bus (USB) on some models, which are also used for loading programs. The microcontrollers can be programmed using the C and C++ programming languages, using a standard API which is also known as the “Arduino language”. In addition to using traditional compiler toolchains, the Arduino project provides an integrated development environment (IDE) and a command line tool developed in Go. It aims to provide a low-cost and easy way for hobbyist and professionals to create devices that interact with their environment using sensors and actuators. Common examples of such devices intended for beginner hobbyists include simple robots, thermostats and motion detectors.
In order to follow the market tread, Orient Display engineers have developed several Arduino TFT LCD displays and Arduino OLED displays which are favored by hobbyists and professionals.
The sizes are 0.96” (160×80), 1.13” (240×135), 1.3” ((240×240), 1.33” (128×128), 1.54” (240×240), 1.77” (128×160), 2.0” (240×320), 2.3” (320×240), 2.4” (240×320), 2.8” (240×320), 3.2” (240×320).
Although Orient Display provides many standard small size OLED, TN and IPS Arduino TFT displays, custom made solutions are provided with larger size displays or even with capacitive touch panel.

This LCD TFT has an onboard controller and 3.3v single voltage for supply and logic. It uses an 8 or 16-bit parallel interface, specified via connections to the display.
Hi guys, welcome to today’s tutorial. Today, we will look on how to use the 1.8″ ST7735 colored TFT display with Arduino. The past few tutorials have been focused on how to use the Nokia 5110 LCD display extensively but there will be a time when we will need to use a colored display or something bigger with additional features, that’s where the 1.8″ ST7735 TFT display comes in.
The ST7735 TFT display is a 1.8″ display with a resolution of 128×160 pixels and can display a wide range of colors ( full 18-bit color, 262,144 shades!). The display uses the SPI protocol for communication and has its own pixel-addressable frame buffer which means it can be used with all kinds of microcontroller and you only need 4 i/o pins. To complement the display, it also comes with an SD card slot on which colored bitmaps can be loaded and easily displayed on the screen.
The schematics for this project is fairly easy as the only thing we will be connecting to the Arduino is the display. Connect the display to the Arduino as shown in the schematics below.
Due to variation in display pin out from different manufacturers and for clarity, the pin connection between the Arduino and the TFT display is mapped out below:
We will use two libraries from Adafruit to help us easily communicate with the LCD. The libraries include the Adafruit GFX library which can be downloaded here and the Adafruit ST7735 Library which can be downloaded here.
We will use two example sketches to demonstrate the use of the ST7735 TFT display. The first example is the lightweight TFT Display text example sketch from the Adafruit TFT examples. It can be accessed by going to examples -> TFT -> Arduino -> TFTDisplaytext. This example displays the analog value of pin A0 on the display. It is one of the easiest examples that can be used to demonstrate the ability of this display.
The second example is the graphics test example from the more capable and heavier Adafruit ST7735 Arduino library. I will explain this particular example as it features the use of the display for diverse purposes including the display of text and “animated” graphics. With the Adafruit ST7735 library installed, this example can be accessed by going to examples -> Adafruit ST7735 library -> graphics test.
The first thing, as usual, is to include the libraries to be used after which we declare the pins on the Arduino to which our LCD pins are connected to. We also make a slight change to the code setting reset pin as pin 8 and DC pin as pin 9 to match our schematics.
Next, we create an object of the library with the pins to which the LCD is connected on the Arduino as parameters. There are two options for this, feel free to choose the most preferred.
Next, we move to the void setup function where we initialize the screen and call different test functions to display certain texts or images. These functions can be edited to display what you want based on your project needs.
The complete code for this is available under the libraries example on the Arduino IDE. Don’t forget to change the DC and the RESET pin configuration in the code to match the schematics.
Uploading the code to the Arduino board brings a flash of different shapes and text with different colors on the display. I captured one and its shown in the image below.
That’s it for this tutorial guys, what interesting thing are you going to build with this display? Let’s get the conversation started. Feel free to reach me via the comment section if you have any questions as regards this project.
