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:

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

This library may have included examples that are not intended to work on all devices, so a failed build may not indicate an actual problem with the library.

The Adafruit TFT FeatherWing has a touch screen display on the front and a socket for any Feather on the back, including the Particle Argon, Boron, and Xenon. You can find technical information at Adafruit.

To download. click the DOWNLOADS button in the top right corner, rename the uncompressed folder Adafruit_ILI9341. Check that the Adafruit_ILI9341 folder contains Adafruit_ILI9341.cpp and Adafruit_ILI9341.

Place the Adafruit_ILI9341 library folder your arduinosketchfolder/libraries/ folder. You may need to create the libraries subfolder if its your first library. Restart the IDE

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

Digital #12 or ICSP MISO - This is the hardware SPI master-in-slave-out pin. By default its digital #12. By cutting a jumper and soldering another on the back, you can move this line from #12 to the ICSP MISO pin. This pin is used for the TFT, microSD and resistive touch screen data

Digital #11 or ICSP MOSI - This is the hardware SPI master-out-slave-in pin. By default its digital #11. By cutting a jumper and soldering another on the back, you can move this line from #11 to the ICSP MOSI pin. This pin is used for the TFT, microSD and resistive touch screen data

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 !

A number of display devices like LEDs, 7-segments, character and graphic displays can be attached to microcontrollers to create an interface between the user and an electronic system for displaying data or controlling the system. Sometimes you may need to add colorful images or graphics to your project, that’s where the TFT color displays come in handy.

TFT LCD is a variant of a liquid-crystal display (LCD) that uses thin-film-transistor (TFT) technology to improve image qualities such as addressability and contrast. In this tutorial we are going to show how to interface a 1.44″ TFT color display based on the ST7735 driver. It has 128×128 color pixels and can display full 16-bit color.

This TFT display uses 3.3V but comes with an on board voltage regulator therefore the VCC can be connected to the Arduino 5V. However for best practice it’s better to use the 3.3V.

Most code Libraries for this TFT ST7735 display with Arduino are programmed with the SDA and SCL pins connected to Arduino pins 11 and 13 respectively. Make sure you don’t change that order otherwise the display may not work.

There are a number of libraries that have been developed to run the TFT ST7735 color display using Arduino but I found the Adafruit-ST7735-Librarythe best to use. Make sure you have this library installed in your IDE.

tft.fillRoundRect(x,y,w,h,r,t); function draws a filled Rectangle with r radius round corners in x and y location and w width and h height and t color.

There are many other functions and commands which you can use to program the TFT color display but the above are the commonest. You will meet many more with practice.

Before we can write our personal code we need to first test the display using the already made code examples from the installed library. This is done by going to File>Examples>Adafruit ST7735 and ST7789 Library. Then you can select any of the examples and upload it to the setup to see if the display works fine.In the diagram below I have shown how to access the graphics test code.

With four bright white LED backlight and 240 x 320 pixels with individual RGB pixel control, this colour 2.8in. 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.
