2 4 tft lcd shield library factory

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.

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!

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.

I"ll show you how to get started with a very popular variant of the TFT touch screen, including how to make a "button" (spoiler alert: it"s not a button just an area of screen that looks like one, that you can then receive touches from).

The 2.4 ” tft lcd touch screen shield for Arduino can be used in a number of applications. However many of the shields available on the market are cloned versions which usually give many hobbyists hard time to use because they do not work properly with the common libraries for running TFT displays.

If you try uploading any of the examples in the Adafruit_GFX library for example the “graphicstest”, the lcd will just give a white screen. Nothing is displayed on the screen!

This problem is mainly due to using a newer version of the Adafruit GFX library. The 1.5.4 release of the Adafruit_GFX library broke compatibility with the Adafruit_TFTLCD library. So you have to roll back to Adafruit_GFX 1.5.3:

Another problem you may encounter with this tft lcd shield is the poor fuctioning of the touch screen. You may find the stylus pen is not well aligned with the content you are writing on the screen.

This is due to a bug in the TouchScreen library therefore you need to locate this library by following the path to where all the libraries for your Arduino IDE are stored.

First change it to return TSPoint(1023-x, 1023-y, z). Save the changes and then compile your code again and upload to check if the touch fuction is fine.

You can keep on adjusting the values of before x and y until you get an ideal point that works best for your tft lcd. Mine worked fine with return TSPoint(x, 1105-y, z)

Due to the limited processing power of the microprocessor in the Arduino, we need to store images in bmp format and they should be 320×240 pixels sizes.

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 .

TFT Screen PinsDigital #13 or ICSP SCLK - This is the hardware SPI clock pin. By default its digital #13. By cutting a jumper and soldering another on the back, you can move this line from #13 to the ICSP clock pin. This pin is used for the TFT, microSD and resistive touch screen data clock

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 , Adafruit GFX Library !

Let"s get started with this creative Arduino project, where you"ll learn about the TFT LCD touch screen and how to use it to create your own colourful calculator. For a basic understanding of touch screen & LCD, a cheap TFT 2.4" Arduino shield is used to create this project. For creating a similar project, one should follow the steps and edit the code for better understanding.

The shield connects ILI9341"s data pins 0-7 to Arduino"s digital pins 2-8 (allowing parallel communication, not SPI. ILI9341"s RESET goes 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 the touchscreen (Although the shield connects some pins of ILI9341 together with pins of the touchscreen).

first, you have to send a command to ILI9341 and then write or read data/parameters. CS pin has to be LOW during the communication, WR rising from LOW to HIGH tells ILI9341 to read byte on data pins.ILI9341 interprets input byte as a command (if RS=0) or as data/parameter (RS=1).

To read a byte from ILI9341 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.

To install this library, you can simply click on the link above which will take you to a Github page. There click on clone or download and select “Download ZIP”. A zip file will be downloaded.

Now, open Arduino IDE and select Sketch -> Include Library -> Add .ZIP library. A browser window will open navigate to the ZIP file and click “OK”. You should notice “Library added to your Libraries” on the bottom-left corner of Arduino, if successful.

You can also find an SD card slot at the bottom of the module shown above, which can be used to load an SD card with BMP image files, and these images can be displayed on our TFT LCD screen using the Arduino Program.

The 2.4” TFT LCD screen is a perfect Arduino Shield. You can directly push the LCD screen on top of the Arduino Uno and it will perfectly match with the pins and slid in through. However, as matters of safety cover the programming terminal of your Arduino UNO with some insulator, just in case if the terminal comes in contact with your TFT LCD screen.
