In this article, you will learn how to use TFT LCDs by Arduino boards. From basic commands to professional designs and technics are all explained here.

In electronic’s projects, creating an interface between user and system is very important. This interface could be created by displaying useful data, a menu, and ease of access. A beautiful design is also very important.

There are several components to achieve this. LEDs,  7-segments, Character and Graphic displays, and full-color TFT LCDs. The right component for your projects depends on the amount of data to be displayed, type of user interaction, and processor capacity.

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. A TFT LCD is an active matrix LCD, in contrast to passive matrix LCDs or simple, direct-driven LCDs with a few segments.

In Arduino-based projects, the processor frequency is low. So it is not possible to display complex, high definition images and high-speed motions. Therefore, full-color TFT LCDs can only be used to display simple data and commands.

In this article, we have used libraries and advanced technics to display data, charts, menu, etc. with a professional design. This can move your project presentation to a higher level.

Size of displays affects your project parameters. Bigger Display is not always better. if you want to display high-resolution images and signs, you should choose a big size display with higher resolution. But it decreases the speed of your processing, needs more space and also needs more current to run.

After choosing the right display, It’s time to choose the right controller. If you want to display characters, tests, numbers and static images and the speed of display is not important, the Atmega328 Arduino boards (such as Arduino UNO) are a proper choice. If the size of your code is big, The UNO board may not be enough. You can use Arduino Mega2560 instead. And if you want to show high resolution images and motions with high speed, you should use the ARM core Arduino boards such as Arduino DUE.

In electronics/computer hardware a display driver is usually a semiconductor integrated circuit (but may alternatively comprise a state machine made of discrete logic and other components) which provides an interface function between a microprocessor, microcontroller, ASIC or general-purpose peripheral interface and a particular type of display device, e.g. LCD, LED, OLED, ePaper, CRT, Vacuum fluorescent or Nixie.

The display driver will typically accept commands and data using an industry-standard general-purpose serial or parallel interface, such as TTL, CMOS, RS232, SPI, I2C, etc. and generate signals with suitable voltage, current, timing and demultiplexing to make the display show the desired text or image.

The LCDs manufacturers use different drivers in their products. Some of them are more popular and some of them are very unknown. To run your display easily, you should use Arduino LCDs libraries and add them to your code. Otherwise running the display may be very difficult. There are many free libraries you can find on the internet but the important point about the libraries is their compatibility with the LCD’s driver. The driver of your LCD must be known by your library. In this article, we use the Adafruit GFX library and MCUFRIEND KBV library and example codes. You can download them from the following links.

By these two functions, You can find out the resolution of the display. Just add them to the code and put the outputs in a uint16_t variable. Then read it from the Serial port by Serial.println(); . First add Serial.begin(9600); in setup().

First you should convert your image to hex code. Download the software from the following link. if you don’t want to change the settings of the software, you must invert the color of the image and make the image horizontally mirrored and rotate it 90 degrees counterclockwise. Now add it to the software and convert it. Open the exported file and copy the hex code to Arduino IDE. x and y are locations of the image. sx and sy are sizes of image. you can change the color of the image in the last input.

Upload your image and download the converted file that the UTFT libraries can process. Now copy the hex code to Arduino IDE. x and y are locations of the image. sx and sy are size of the image.

In this template, We just used a string and 8 filled circles that change their colors in order. To draw circles around a static point ,You can use sin();  and cos(); functions. you should define the PI number . To change colors, you can use color565(); function and replace your RGB code.

In this template, We converted a .jpg image to .c file and added to the code, wrote a string and used the fade code to display. Then we used scroll code to move the screen left. Download the .h file and add it to the folder of the Arduino sketch.

In this template, We used sin(); and cos(); functions to draw Arcs with our desired thickness and displayed number by text printing function. Then we converted an image to hex code and added them to the code and displayed the image by bitmap function. Then we used draw lines function to change the style of the image. Download the .h file and add it to the folder of the Arduino sketch.

In this template, We created a function which accepts numbers as input and displays them as a pie chart. We just use draw arc and filled circle functions.

while (a < b) { Serial.println(a); j = 80 * (sin(PI * a / 2000)); i = 80 * (cos(PI * a / 2000)); j2 = 50 * (sin(PI * a / 2000)); i2 = 50 * (cos(PI * a / 2000)); tft.drawLine(i2 + 235, j2 + 169, i + 235, j + 169, tft.color565(0, 255, 255)); tft.fillRect(200, 153, 75, 33, 0x0000); tft.setTextSize(3); tft.setTextColor(0xffff); if ((a/20)>99)

while (b < a) { j = 80 * (sin(PI * a / 2000)); i = 80 * (cos(PI * a / 2000)); j2 = 50 * (sin(PI * a / 2000)); i2 = 50 * (cos(PI * a / 2000)); tft.drawLine(i2 + 235, j2 + 169, i + 235, j + 169, tft.color565(0, 0, 0)); tft.fillRect(200, 153, 75, 33, 0x0000); tft.setTextSize(3); tft.setTextColor(0xffff); if ((a/20)>99)

In this template, We display simple images one after each other very fast by bitmap function. So you can make your animation by this trick.  Download the .h file and add it to folder of the Arduino sketch.

In this template, We just display some images by RGBbitmap and bitmap functions. Just make a code for touchscreen and use this template.  Download the .h file and add it to folder of the Arduino sketch.

The speed of playing all the GIF files are edited and we made them faster or slower for better understanding. The speed of motions depends on the speed of your processor or type of code or size and thickness of elements in the code.

It might help if I give more scope for my application. My current project runs on a PIC32MX 80MHz,output is to a320x 240 TFT, coded in C and using Mikro C and their closed TFT library. The code is over 5,000 lines and has the following IC2 sensors, light, BME280 (humidity, temp, pressure), DS3231 RTC, also connected is a GPS read by a UART, user control is via rotary encoder and center push switch. The user selects one of 7 top level menu/screens and the display then updates for the selection, this requires most of the display to update. The display can be set to show updating graphs for temp, humidity and pressure for last 24 hours and 7 days. The problem is there is now too much data to show on a 320 x 240 screen, it really needs a larger screen with higher resolution, the PIC32 with Mikro TFT library is on it"s limit updating the current screen so a faster CPU with better TFT libraries is needed or make a big change and move to a Rpi. The actual screen updates are not that fast after each screen is initially redrawn, I have limited updates to only parts of the screen to keep flicker/updates less noticeable. The only constant screen updating is the time being shown in larger type font at the top of the screen and this changes only once /sec.

So for the question of preferred library and or screen, I should have really asked what Teensy 3.6 libraries are available for any controller type suitable to drive a 5" TFT display at 800 x 400?

Looking on Adafruits webpage they have the RA8875 Driver Board for 40-pin TFT Touch Displays - 800x480 Max and a library available which might work with the Teensy, then add their 5.0" 40-pin TFT Display - 800x480 with Touchscreen. But it would be good to know if alternative Displays exist that have been tested and any better libraries written to drive them, that work with Teensy. I don"t have the coding skills to write my own Libraries or modify existing ones as I only started coding in C last year.

2017/03 To Small-medium TFT-LCD requirement, RAIO announce its new RA8871M/RA8873M controller, with the powerful features make the device suitable for both HVGA and WVGA display applications in the mainstream market.

2015/02RAIO launches new products - RA8876/RA8877, with up to 64M Byte external SDRAM used for frame buffer, RA8876/RA8877 is suitable for displaying up to WXGA resolution (1366x768) at 24bit colors.

Remember it"s an SPI connection so there"s hardware limitations on some CPU, for example DUE can use as CS pin 4,10 or 52, Teensy can use more but not all, 8 Bit arduino can use almost any, etc..

Are you sure you connect everything fine, settings are ok, you are using the correct CS pin, you don"t have any other SPI devices sharing the same line, the display has correct jumper set and you are sure that display it"s correct supplied (and the supply it"s stable, check also this!) but you still have nothing on screen?

This is the first attemp to create a library that use all the features of this chip from scratch and have nothing to share with the Adafruit_RA8875 library.

This library will work also with the Adafruit board but was mainly coded for the many TFT displays from china makers that use this chip, some are quite good and cheap, like the EastRising from buydisplay.com, much cheaper than adafruit.

For CS pin you have to choose between these pin on Teensy3.1: 2,6,9,10,15,20,21,22,23. Arduino UNO,MEGA and almost all 8 bit variants can use any pin, DUE can use as CS only 4,10 or 52 (please check DUE specifications)

Current beta has a optional Teensy instance that can use alternative SPI pinouts, this let you use Audio Board from PJRC that uses the classic SPI pinouts for RX and SD cs. You can test it with Spectrum Analyzer example that uses the Audio Board with a RA8875 TFT screen and thanks to the hardware accelleration of this chip and the use of onchip screen buffer it let you have large screen with touch capabilities with high-end audio manipulation.
