Features:2.4" diagonal LCD TFT Touch Panel displayBright, 4 white-LED backlight, on by default but you can connect the transistor to a digital pin for backlight controlColorful, 18-bit 262,000 different shades4-wire resistive touchscreen8 bit digital interface, plus 4 control linesUses digital pins 5-13 and analog 0-3. That means you can use digital pins 2, 3 and analog 4 and 5. Pin 12 is available if not using the micro SD5V compatible, use with 3.3V or 5V logicFor Arduino UNO R3 MEGA2560

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).

To read a byte from ILI after sending a read command (e.g. 09h - Read Display Status) set RD from HIGH to LOW, so ILI9341 outputs data until RD returns HIGH. (see code)

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.

Then we need to read a position of a touch. So we set one of the X wires to HIGH (which one depends on on which side of touch screen we want to read min/max value; see variant A/B in the code) and we read analog value on Y. The value should be in the range 0-1023, but touchscreen I tested returns 110-910 (So it need to be calibrated - run ILI9341_7.ino). Then we apply LOW-HIGH on Y layer and read analog value on X.

Spice up your Arduino project with a beautiful touchscreen display shield with built in microSD card connection. This TFT display is 2.4" diagonal and colorful (18-bit 262,000 different shades)! 240x320 pixels with individual pixel control. As a bonus, this display has a optional capacitive touch panel and resistive touch panel with controller XPT2046 attached by default.

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.

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.

With four bright white LED backlight and 240 x 320 pixels with individual RGB pixel control, this colour 2.4in. TFT display features a resistive touchscreen for fingertip detection across the entire screen surface. The workload is lifted from the microcontroller by a built-in controller equipped with RAM buffering, and the display board has two modes: 8-bit and SPI.

Add some jazz & pizzazz to your project with a color touchscreen LCD. This TFT display is 2.4" diagonal with a bright (4 white-LED) backlight and it"s colorful! 240x320 pixels with individual RGB pixel control, this has way more resolution than a black and white 128x64 display.

If you need a larger touchscreen, check out the 2.8" diagonal or 3.5" diagonal TFT breakouts. For a smaller display, see our non-touch 2.2" or 1.8" or 1.44" diagonalTFTs
