2.8 tft lcd shield arduino uno manufacturer

This is SainSmart UNO R3 and 2.8 inch TFT LCD module with the TFT LCD shield kit For arduino enthusiasts.It includes one pcs of sainsmart UNO R3, one pcs of 2.8 inch TFT LCD display and a TFT LCD shield. We will provided you the whole document including the example project of arduino UNO(R3) with the kit. We will supply you the technical support after your purchase.

The SainSmart Uno R3 is a microcontroller board based on the ATmega328 . It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.

1.0 pinout: added SDA and SCL pins that are near to the AREF pin and two other new pins placed near to the RESET pin, the IOREF that allow the shields to adapt to the voltage provided from the board. In future, shields will be compatible with both the board that uses the AVR, which operates with 5V and with the Sainsmart Due that operates with 3.3V. The second one is a not connected pin, that is reserved for future purposes.

SainSmart 2.8" 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 mutilfunctional module for your project.The Screen include a controller ILI9325, it"s a support 8/16bit data interface , easy to drive by many MCU like arduino families,STM32 ,AVR and 8051. It is designed with a touch controller in it . The touch IC is XPT2046 , and touch interface is included in the 40 pins breakout. It is the version of product only with touch screen and touch controller.

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.

This is SainSmart TFT LCD Extend shield for UNO(R3) .Using this shield can help you out of the bothers to use other cables. You just need to plug the module to arduino UNO(R3) through this shield.

If you connect the touch screen LCD with UNO R3, the touch screen function will be useless . If you want to use the touch function, please connect the LCD with Mega2560 (R3) or Due (R3).

2.The LCD is compatible for arduino family,but the Shield is just for the arduino UNO R3. If you need the LCD Extend shield for other arduinos, you need another shield which is also provided from our store.

The item is a professional and practical UNO R3 2.8″ TFT touch screen with SD card socket, which is mainly made of durable hard PCB board and metal materials, and can be used for Arduino board module.

Spice up your Arduino project with a touchscreen display shield with built in microSD card connection. This TFT display is big (2.8″ diagonal) bright (4 white-LED backlight) and colorful (18-bit 262,000 different shades)! 240×320 pixels with individual pixel control. As a bonus, this display has a resistive touchscreen attached to it already, so you can detect finger presses anywhere on the screen.

This is the newest version from Adafruit – it has been updated from their original v1 shield to an SPI display – its a tiny bit slower but uses a lot less pins and is now much easier to use with Mega & Leonardo. Adafruit also includes an SPI touchscreen controller so you only need one additional pin to add a high quality touchscreen controller. This display shield has a controller built into it with RAM buffering, so that almost no work is done by the microcontroller.

The shield ships fully assembled, tested and ready to go. No wiring, no soldering! Simply plug it in and load up the Arduino Library Adafruit provides (see links below). It will be up and running in under 10 minutes! The shield works best with any classic Arduino (UNO/Duemilanove/Diecimila). Solder three jumpers and you can use it at full speed on a Leonardo or Mega as well.

The 2.8 inch TFT Touch Screen LCD Module For Arduino is a beautiful large touchscreen display shield with built in microSD card connection. The LCD has excellent vivid color contrast. This TFT display is big (2.8″ diagonal) bright (4 white-LED backlights) and colorful (18-bit 262,000 different shades). 240×320 pixels with individual pixel control. 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.

As with all Arduino Shields, connecting to the Arduino is simply a matter of plugging the shield in. Take care to align the pins correctly, and ensure the bottom of the shield does not make contact with the Arduino USB port.

Note: The following picture is the connection diagram of the 2.8-inch TFT screen and Arduino uno, but this product is connected in exactly the same way.

If the Arduino board has an ICSP interface, set the SPI Config switch on the display module to the ICSP direction (by default) (the company"s Arduino UNO motherboard has an ICSP interface, just plug it in directly.).

This product uses the same LCD control chip and touch panel control chip as the 3.5-inch TFT screen of the same series of our company, so the code is completely compatible. The following takes 3.5-inch TFT as an example to introduce.

LCD_Show can display colorful patterns with different shapes and times. LCD_ShowBMP is for displaying the picture in BMP, and LCD_Touch is for using the touching function.

The display controller used in this product is ILI9486, and we need to initialize the controller through the SPI communication protocol, and the initialization functions are written in LCD_Driver.cpp.

The function functions related to the screen display are written in LCD_GUI.cpp. The function of each function and the parameters passed are explained in the source code. You can call it directly when you need to use it.

Before using LCD_ShowBMP to display pictures, first copy the pictures in the PIC folder in the data to the root directory of the SD card (you should understand that in the root directory, that is to save the pictures directly to the SD card, do not put them in any subfolders folder.).

These functions are all written in LCD_Bmp.cpp. In fact, the image data in BMP format with a specific file name is read from the SD card, and then the display function written by us is called to re-express the data as an image.

In fact, you can also use Image2Lcd image modulo software to convert images of different sizes and formats into array data, and then use the functions we wrote to display them.

Note: The following picture is the connection diagram of the 2.8-inch TFT screen and XNUCLEO-F103RB, but this product is connected in exactly the same way.

The demos are developed based on the HAL library. Download the program, find the STM32 program file directory, and open STM32\XNUCLEO-F103RB\lcd4in-demo\MDK-ARM\ lcd4in-demo.uvprojx.

This product uses the same LCD control chip and touch panel control chip as the 3.5-inch TFT screen of the same series of our company, so the code is completely compatible. The following takes 3.5-inch TFT as an example to introduce.

After running the demo, it displays some characters and patterns at first, then displays four pictures, and finally displays the touch sketchpad function. Actually, three projects in the Arduino platform code are integrated in the main function, we place the three main functions in sequence and place TP_DrawBoard(); in an infinite loop to achieve the above functions.

Before using LCD_ShowBMP to display pictures, copy the pictures in the PIC folder in the data to the root directory of the SD card, and then insert the SD card into the SD card slot on the back of the screen to start the download program verification.

In fact, you can also use Image2Lcd image modulo software to convert images of different sizes and formats into array data, and then use the functions we wrote to display them.

This is a keyestudio 2.8 inch TFT LCD shield with touchscreen. This TFT display is driven with ILI9325 chip and has 240x320 pixels with individual RGB pixel control.
