2.4 tft lcd shield datasheet brands
The 2.4 inch TFT Touch Screen Module with micro SD card slot is now available as a SHIELD for Arduino UNO. It has a four wire resistive touch screen, a micro SD card socket, a reset switch and a convenient Arduino Uno shield footprint.
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.
ILI9341 is integrated inside the display. It drives the display and has nothing to do with touchscreen (Although the shield connects some pins of ILI9341 together with pins of the touchscreen).
The touch screen is attached on the surface of the display. It connects through 4 wires, which share arduino pins 8, 9, A2, A3 with ILI. So you can"t write to LCD display and read the touch screen in the same time.
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.
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.

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 is Sainsmart 2.4 inch TFT LCD module with the TFT LCD shield kit for arduino enthusiasts.It includes one piece of 2.4 inch TFT LCD display and a TFT LCD shield for Arduino MEGA2560 (R3).We will provided you the whole document including the example project of arduino due with the kit. We will supply you the technical support after your purchase.
Voltage type: 5v or 3v voltage input voltage,input is selectable. Because TFT can only work under 3.3 V voltage, so when the input voltage VIN is 5V, need through the 3.3 V voltage regulator IC step down to 3.3V , when the input voltage of 3.3 V, you need to use the zero resistance make J2 short , is equivalent to not through the voltage regulator IC for module and power supply directly.(Click here)
It is 100% compatible with the normal MCU like ARM AVR PIC and 8051,especially on arduino family such as arduino due and arduino mega2560(R3).The module uses the LCD controller Chip SSD1963 with 5 inch LCD including the touchscreen.
The shield defines that all the the data transmit ports are PC1-PC8 and PC12-PC19,the controll pins are PD0-PD3.The perfect design could realize that the data transmits in high speed.The SPI interface is designed in the ISP header of arduino due so that the SPI transfer with DMA could be achieved in high speed with no drag.
The shield is fully assembled, tested, and ready to go. No wiring, no soldering! Simply plug it in and load up the library - you"ll have it running in under 10 minutes!
As a 2.4inch TFT display module with a resolution of 240 * 320, it uses the SPI interface for communication. LCD has an internal controller with basic functions, which can be used to draw points, lines, circles, and rectangles, and can display English, Chinese as well as pictures.
The 2.4inch LCD uses the PH2.0 8PIN interface, which can be connected to the Raspberry Pi according to the above table: (Please connect according to the pin definition table. The color of the wiring in the picture is for reference only, and the actual color shall prevail.)
The LCD supports 12-bit, 16-bit, and 18-bit input color formats per pixel, namely RGB444, RGB565, and RGB666 three color formats, this demo uses RGB565 color format, which is also a commonly used RGB format.
For most LCD controllers, the communication mode of the controller can be configured, usually with an 8080 parallel interface, three-wire SPI, four-wire SPI, and other communication methods. This LCD uses a four-wire SPI communication interface, which can greatly save the GPIO port, and the communication speed will be faster.
2. The module_init() function is automatically called in the INIT () initializer on the LCD, but the module_exit() function needs to be called by itself
Python has an image library PIL official library link, it do not need to write code from the logical layer like C, can directly call to the image library for image processing. The following will take 1.54inch LCD as an example, we provide a brief description for the demo.
The 2.4 inch TFT LCD Touch Display Shield for Arduino Uno is fully assembled, tested and ready to go. Add the touch display without wiring, no soldering! Simply plug it in and load up a library – you ‘ll have it running in under 10 minutes! Works best with any classic Arduino ATMEGA328 Board
