After googling for hours I see that the AdaFruit library has been modified for this driver chip but it seems from all the example code I"ve viewed they all use an 8-bit parallel interface.

I"ve attached the pin-out picture. From what I can tell the Mega-2560 header doesn"t quite have enough D-I/O pins on this header for all the pins on the TFT; Seems short by exactly 1-row (2-pins). I was thinking since the top/bottom row of the Mega-2560 are 5Vdc or GND depending on which end. Perhaps "CS"/"RS" or "T_CS"/"CLK" could be tied directly however from what I can gather "RS" is equivalent to "LCD_DC" which is heavily used/switched so it cannot be tied directly to GND like I"m figuring "CS" could be. I"m not sure what "T_CS" and "CLK" are for short of guessing Transmissive Touch Clock?? Any ideas?

Worst comes to worst; I"m thinking of just heating and pushing 2-pins of the TFT header up through the PCB and adding 2-jumper wires to other parts of the Mega-2560. Has anyone tried powering one of these using D-I/O pins?

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.

Today, you will learn how you can create and use buttons in your Arduino TFT Touchscreen projects.I"m using Kuman"s 2.8" TFT Shield combined with Kuman"s Arduino UNO. Bonus: The TFT Shield from Kuman comes with a free Stylus which you can use for more precise presses!

Clip in the shield onto your Arduino board. Make sure it"s not in the wrong way!You can use the pictures above for reference. Plug in your Arduino board to your PC and hop into the Arduino Software.

For the example that I"ve prepared, you can use the code that you can find here. I"ve added some comments, to make things more clear. After uploading, you can check if the display is working correctly by pressing the button. If so, the screen will change and a text will appear.

If your presses remain unrecognized, you can calibrate the display by changing the values at the top of the code (TS_MINX, TS_MAXX, TS_MINY and TS_MAXY). The button works by checking where the screen is being pressed and if it"s inside the coordinates of the button itself, a click is registered. If the above-mentioned values are not correct, the click-registering will be off

I tried it with your sketch, but it did not work firstly. However I fixed some part of the sketch, it worked. "tft.begin(0x9325);" to " tft.begin(0x9341);"0

This is a 2.8” TFT Resistive Touchscreen Display. The module, with a resolution of 320x240, adopts ILI9341 as driver IC and SPI (4-line) communication mode. The board integrates touch chip XPT2046, which converts the touch data collected by the AD to SPI data. The module also integrates an SD card slot allowing you to easily read the full-color bitmap. There are two modes of wiring supplied, normal pin header wiring and GDI. The latter one requires to work with a main controller board with a GDI interface (e.g. FireBeetle-M0). You can use it with only one FPC line plugging in, which reduces the complexity of the wiring. Furthermore, it features high resolution, wide viewing angle, and simple wiring, which can be used in all sorts of display applications, such as, IoT controlling device, game console, desktop event notifier, touch interface, etc.

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.

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 Fantastic 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 comes with a resistive or capacitive touchscreen attached to it already, so you can detect finger presses anywhere on the screen.

There"s two versions of the shield. One has a resistive touch screen, one has a capacitive one. The TFT display and pinouts is the same for both. The microSD card is the same too. The differences come in on the touch screen controller.

The TFT LCD library is based off of the Adafruit GFX graphics core library. GFX has many ready to go functions that should help you start out with your project. Its not exhaustive and we"ll try to update it if we find a really useful function. Right now it supports pixels, lines, rectangles, circles, round-rects, triangles and printing text as well as rotation.

We have example code ready to go for use with these TFTs. Libraries need to be downloaded and installed. Such as:dmtftlibrary,Adafruit ILI9341 library, andAdafruit GFX Library!
