The ILI9341 TFT module contains a display controller with the same name: ILI9341. It’s a color display that uses SPI interface protocol and requires 4 or 5 control pins, it’s low cost and easy to use. The resolution of this TFT display is 240 x 320 which means it has 76800 pixels. This module works with 3.3V only and it doesn’t support 5V (not 5V tolerant).

The ILI9341 TFT display board which is shown in the circuit diagram above has 14 pins, the first 9 pins are for the display and the other 5 pins are for the touch module.

So, the display side pins which numbered from 1 to 9 are (from left to right): VCC (5V), GND (ground), CS (chip select), RST (reset), DC (or D/C: data/command), MOSI (or SDI), SCK (clock), BL (back light LED) and MISO (or SDO).

As mentioned above, the ILI9341 TFT display controller works with 3.3V only (power supply and control lines). The display module is supplied with 5V that comes from the Arduino board. This module has a built-in 3.3V regulator which supplies the display controller with 3.3V from the 5V source.

To connect the Arduino to the display module, I used voltage divider for each line which means there are 5 voltage dividers. Each voltage divider consists of 2.2k and 3.3k resistors, this drops the 5V into 3V which is sufficient.

The first library is a driver for the ILI9341 TFT display which can be installed from Arduino IDE library manager (Sketch —> Include Library —> Manage Libraries …, in the search box write “ili9341” and choose the one from Adafruit).

The ILI9341 TFT display is connected to Arduino hardware SPI module pins (clock and data), the other pins which are: CS (chip select), RST (reset) and DC (data/command) are defined as shown below:

The following Arduino code is from Adafruit ILI9341 library (graphicstest.ino) with some modifications in order to work with the above circuit diagram.

Unfortunately this adapter is set to 9 bit SPI mode via the mode pins IM0-IM3. If you want to patch this - like I have done - you have to desolder the TFT from the pcb to cut some traces. This is a flexible print. Only for people with soldering skills !

You also have to get access to pin 36 for the dc signal. Cut the GND connection. You can use the level converter used for the LCD_LED signal. Mosfet Q1 can be driven with a logic signal without converter. Watterott will change this in a future revision.

To print characters to a graphic screen we need a font. To code a font by paper is ok for a small lcd, but for a 320*240 pixel display we need bigger fonts. A 12*12 pixel font is readable, but a lot of work to construct.

In this Arduino touch screen tutorial we will learn how to use TFT LCD Touch Screen with Arduino. You can watch the following video or read the written tutorial below.

As an example I am using a 3.2” TFT Touch Screen in a combination with a TFT LCD Arduino Mega Shield. We need a shield because the TFT Touch screen works at 3.3V and the Arduino Mega outputs are 5 V. For the first example I have the HC-SR04 ultrasonic sensor, then for the second example an RGB LED with three resistors and a push button for the game example. Also I had to make a custom made pin header like this, by soldering pin headers and bend on of them so I could insert them in between the Arduino Board and the TFT Shield.

Here’s the circuit schematic. We will use the GND pin, the digital pins from 8 to 13, as well as the pin number 14. As the 5V pins are already used by the TFT Screen I will use the pin number 13 as VCC, by setting it right away high in the setup section of code.

I will use the UTFT and URTouch libraries made by Henning Karlsen. Here I would like to say thanks to him for the incredible work he has done. The libraries enable really easy use of the TFT Screens, and they work with many different TFT screens sizes, shields and controllers. You can download these libraries from his website, RinkyDinkElectronics.com and also find a lot of demo examples and detailed documentation of how to use them.

After we include the libraries we need to create UTFT and URTouch objects. The parameters of these objects depends on the model of the TFT Screen and Shield and these details can be also found in the documentation of the libraries.

So now I will explain how we can make the home screen of the program. With the setBackColor() function we need to set the background color of the text, black one in our case. Then we need to set the color to white, set the big font and using the print() function, we will print the string “Arduino TFT Tutorial” at the center of the screen and 10 pixels  down the Y – Axis of the screen. Next we will set the color to red and draw the red line below the text. After that we need to set the color back to white, and print the two other strings, “by HowToMechatronics.com” using the small font and “Select Example” using the big font.

This new library is a standalone library that contains the TFT driver as well as the graphics functions and fonts that were in the GFX library. This library has significant performance improvements when used with an UNO (or ATmega328 based Arduino) and MEGA.

Examples are included with the library, including graphics test programs. The example sketch TFT_Rainbow_one shows different ways of using the font support functions. This library now supports the "print" library so the formatting features of the "print" library can be used, for example to print to the TFT in Hexadecimal, for example:

To use the F_AS_T performance option the ILI9341 based display must be connected to an MEGA as follows:MEGA +5V to display pin 1 (VCC) and pin 8 (LED) UNO 0V (GND) to display pin 2 (GND)

In the library Font 0 (GLCD font), 2, 4, 6 and 8 are enabled. Edit the Load_fonts.h file within the library folder to enable/disable fonts to save space.

TFT_ILI9341 library updated on 1st July 2015 to version 12, this latest version is attached here to step 8:Minor bug when rendering letter "T" in font 4 without background fixed

Compared to SPI, the parallel interface on this board is fast and it responds well to boards with faster clock speeds! If you really want to get the most out of this display, I highly recommend going to a 32 bit board.

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.

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.

I bought this TFT displayFree delivery and returns on eligible orders. Buy DollaTek 2.4 inch TFT SPI LCD module ILI9341 drive color display panel with PCB panel 8 pins screen at Amazon UK.

color_palette (Optional): The type of color pallet that will be used in the ESP’s internal 8-bits-per-pixel buffer. This can be used to improve color depth quality of the image. For example if you know that the display will only be showing grayscale images, the clarity of the display can be improved by targeting the available colors to monochrome only. Options are:

4. Select Enable code generation for Dashboard blocks and click Launch Display Configuration Setup to launch the wizard to configure the dashboard properties.

Due to memory constraints, the appplication dashboard may not deploy on an Arduino board with less memory than the Arduino Mega 2560 board, such as an Arduino Uno or Arduino Leonardo. To ensure successful deployment of the application dashboard on your Arduino board, consider deploying a dashboard that consists of only a few dashboard elements. For example, you can remove the Display dashboard block to reduce the memory size of the application dashboard.

Arduino Due board does not support the touch screen capability of the Adafruit ILI 9341 Touch TFT display. To try this example on the Arduino Due board, use one of these solutions:

2. Use a custom display that the Arduino Due board supports. Note that you must configure this display in the Display properties section of the Configuration Parameters dialog box.

Implement the dashboard on a custom graphical display. Make sure to appropriately configure the Dashboard properties in the Configuration Parameters dialog box. Use the datasheet for the display to ensure you make the correct connections with your Arduino board.

Implement the dashboard panel on the LCD display of your choice for the Arduino Based Smart Watering of Plants example. Use the Display and Push Button blocks to implement the dashboard.
