2.8 tft color lcd touch screen shield for arduino mega supplier
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. As a bonus, this display has a optional resistive touch panel with controller XPT2046 attached by default and a optional capacitive touch panel with controller FT6206 attached by default, so you can detect finger presses anywhere on the screen and doesn"t require pressing down on the screen with a stylus and has nice glossy glass cover.
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! Works best with any classic Arduino (UNO/Due/Mega 2560).
This display shield has a controller built into it with RAM buffering, so that almost no work is done by the microcontroller. You can connect more sensors, buttons and LEDs.
Of course, we wouldn"t just leave you with a datasheet and a "good luck!" - we"ve written a full open source graphics library at the bottom of this page that can draw pixels, lines, rectangles, circles and text. We also have a touch screen library that detects x,y and z (pressure) and example code to demonstrate all of it. The code is written for Arduino but can be easily ported to your favorite microcontroller!
If you"ve had a lot of Arduino DUEs go through your hands (or if you are just unlucky), chances are you’ve come across at least one that does not start-up properly.The symptom is simple: you power up the Arduino but it doesn’t appear to “boot”. Your code simply doesn"t start running.You might have noticed that resetting the board (by pressing the reset button) causes the board to start-up normally.The fix is simple,here is the solution.

Add some pizazz to your arduino project with a beautiful large touchscreen display shield with built in MicroSD card slot and a capacitive touchscreen. This TFT display is big (2.8" diagonal) bright (4 white-led backlight) and colorful (262, 000 different colors!) 240x320 pixels with individual pixel control. It has a lot more resolution than a black and white 128x64 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 is the capacitive version as opposed to the resistive touchscreen we also sell. This touchscreen doesn"t require pressing down on the screen with a stylus, and has a nice glossy glass cover. It is a single-touch display. 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 IEC bus with other i²c devices. 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! 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. This display shield has a controller built into it with ram buffering, so that almost no work is done by the controller. 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. Of course, we wouldn"t just leave you with a data sheet and a" good luck!" - we"ve written a full open source graphics library that can draw pixels, lines, rectangles, Circles and text.
This TFT Touch Shield is Arduino/Crowduino/Arduino Mega compatible, it integrated a 2.8” TFT Display and a resistive touch panel, to make this shield suitable for handheld devices.
This TFT Touch Shield has 240x320 pixels with individual pixel control, it uses the ILI9341 driver and SPI interface to communicate with controllers such as Arduino, saving you much Arduino pins for other usages in your projects. Besides, A SD card socket is also added to help you develop applications that data storage is needed such as digital picture album.
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.
Click to download the Touch Screen Driver,then please click on below button to download the library and install it, if you don"t know how to install an Arduino library, please refer to the tutorial (HOW TO INSTALL AN ARDUINO LIBRARY).
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.
The Raw ADC value has to be converted to Pixel Co-ordinates. This is done with map function. This mapping changes for v0.9 and v1.0. The demo applications already takes care of this mapping.
The parameters TS_MINX, TS_MAXX, TS_MINY and TS_MAXY actually decides the extreme ends of the touch screen and actually forms the calibration parameters.
I compared the serial values that are printed between the previously mentioned NANO connected to this display with hardware SPI and default SD library compared to the exact same display and SD card connected to a MEGA and using the SDFat.h file. I am including that serial output here:

Please Note: This shield does work with the Arduino Mega’s but its going to be half the speed of the Uno-type boards because of the way the Mega rearranges all the pins (there is no way to get around this!)
This is 320x240 resolution 2.8-inch touch display, it supports development boards such as Arduino UNO board and Mega2560 board or boards compatible with UNO without wiring. By adopting 8-bit parallel bus, it can refresh quicker and smoother than SPI. It supports 16-bit RGB 65K color display that can provide the rich color display.
