2.8 tft lcd shield pinout manufacturer
This is a versatile and Arduino/Seeeduino/Arduino Mega compatible resistive touch screen shield which can be used as display device, or sketch pad for user input/interface.
Compared with the previous version (2.8" TFT Touch Shield V1.0) we improved the screen driver with a professional chip (ILI9341) to provide the pin-saving SPI communication protocol without sacrificing the data transmission speed.
Circles isn"t the only thing our library can help you draw, we also have a lines, number, rectangle, and many more examples. Check those out as well to become a pro with the shield.
Function Description: The drawCircle function draws an empty circle with the center at the coordinates poX, and poY. The circle will be of radius r and the border color will be color. The color parameter is a 16-bit Red-Geen-Blue (RGB) integer, in the example code above the words YELLOW, CYAN, RED, and BLUE are defined as integers in the TFTv2.h file.
The TFT Touch Shield"s backlight is on by default since its control circuit is directly powered by the 5V pin. If, however, you wish to control the backlight"s on/off state using the Arduino Digital I/O pin 7, a simple modification will have to be made:
Combining Arduino and other shield modules, we make a mobile phone named Arduino Phone. Meanwhile, we printed a shell for it with the 3D printer. Although it"s not such fine as you think, even a little bit clunky, it"s still very cool. That is the point this is a cell phone made by ourselves.
TFT Touch Shield V2.0 is a resistive touch screen, compatible with Arduino/Seeeduino/Arduino Mega/SAMD21 platforms. It can be used as display device or sketch pad. Compared with the previous version, 2.8""TFT Touch Shield V1.0, we upgraded the screen driver to a more professional chip, ILI9341 driver, providing different pin-saving SPI communication without sacrificing the data transmitting speed. Due to the communication method change, programs developed for the original version are needed for modification before being transplanted to the new version. With a SD card module integrated on this shield, this shield reserves capability for other expansions of your project.
We recommend using Seeed_Arduino_LCD with internal flash chips larger than 128k. If you have a smaller flash device, I recommend using the TFT_Touch_Shield_V2.
Step1. Download and Install Seeed_Arduino_LCD. if you don"t know how to install an Arduino library, please refer to the tutorial (HOW TO INSTALL AN ARDUINO LIBRARY).
2.8" TFT Touch Shield is an Arduino / Arduino Mega compatible multicolored TFT display with a 4-wire resistive touch screen. It includes an Arduino shield compatible footprint for attachment. The TFT driver is based on professional Driver IC and with 8 bit data and 4 bit control interface.
The TFT library provides the following Application Programming Interfaces(API). The library makes use of direct access to PORT registers instead of Arduino APIs. This is to increase the speed of communication between MCU and TFT. At present, the library supports Arduino, Arduino Mega (1280 or 2560) and Seeeduino ADK Main Board compatible boards. In Mega the 8bit data port of TFT is distributed to different pins belonging to different ports. This decreases the speed of graphics drawing when compared to Arduino. The choice of port pins are purely based on Arduino / Mega port pin arrangement.
TFT Touch Shield uses the Adafruit Touch Screen Library. To understand the principle behind resistive touch screen refer External Links. In short, a 4-wire resistive touch screen provides two voltage divider each for X and Y axis. By applying proper voltages for each axis and scanning the ADC values the position of the touch can be detected. These values are always prone to noise. Hence a digital filter is used.
Spice up your Arduino project with a beautiful large 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)! 240x320 pixels with individual pixel control. It has way more resolution than a black and white 128x64 display. As a bonus, this display has a resistive touchscreen attached to it already, so you can detect finger presses anywhere on the screen.
The shield is fully assembled, tested and ready to go. No wiring, no soldering! Simply plug it in and load up our library - you"ll have it running in under 10 minutes!
This display shield has a controller built into it with RAM buffering, so that almost no work is done by the microcontroller. The shield does require a lot of pins: 12 lines total for the display, 13 total if you use the microSD card

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.
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.

Arduino 2.8"" TFT Touch Shield is an Arduino UNO/ Mega compatible multicolored TFT display with a touch-screen and SD card socket. It is available in an Arduino shield compatible pinout for attachment. The TFT driver is based on ILI9325DS with 8bit data and 4bit control interface.
This 2.8″ TFT Touch Shield for Arduino with Capacitive Touch 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. It has way more resolution than a black and white 128×64 display. As a bonus, this display has a capacitive touchscreen attached to it already, so you can detect finger presses anywhere on the screen.
This shield uses SPI for the display and SD card and is easier to use with UNO, Mega & Leonardo Arduino’s. The capacitive touchscreen controller uses I2C but you can share the I2C bus with other I2C devices.
This display shield has a controller built into it with RAM buffering, so that almost no work is done by the microcontroller. This shield needs fewer pins than our v1 shield, so you can connect more sensors, buttons and LEDs: 5 SPI pins for the display, 2 shared I2C pins for the touchscreen controller and another pin for uSD card if you want to read images off of it.
Please see the DT028CTFT for reference designs. The schematics between the B and the C are the same with the exception that the B does not have the IPS interface.
