As a bonus, this display has a optional 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!

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. At the end of this article, you can :Write texts and numbers with your desired font.

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 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 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.

You must add the library and then upload the code. If it is the first time you run an Arduino board, don’t worry. Just follow these steps:Go to www.arduino.cc/en/Main/Software and download the software of your OS. Install the IDE software as instructed.

The second adds a library that supports drivers of MCUFRIEND Arduino display shields.#include "TouchScreen.h" // only when you want to use touch screen#include "bitmap_mono.h" // when you want to display a bitmap image from library#include "bitmap_RGB.h" // when you want to display a bitmap image from library#include "Fonts/FreeSans9pt7b.h" // when you want other fonts#include "Fonts/FreeSans12pt7b.h" // when you want other fonts#include "Fonts/FreeSerif12pt7b.h" // when you want other fonts#include "FreeDefaultFonts.h" // when you want other fonts#include "SPI.h" // using sdcard for display bitmap image#include "SD.h"

fillScreen function change the color of screen to t color. The t should be a 16bit variable containing UTFT color code.#define BLACK 0x0000#define NAVY 0x000F#define DARKGREEN 0x03E0#define DARKCYAN 0x03EF#define MAROON 0x7800#define PURPLE 0x780F#define OLIVE 0x7BE0#define LIGHTGREY 0xC618#define DARKGREY 0x7BEF#define BLUE 0x001F#define GREEN 0x07E0#define CYAN 0x07FF#define RED 0xF800#define MAGENTA 0xF81F#define YELLOW 0xFFE0#define WHITE 0xFFFF#define ORANGE 0xFD20#define GREENYELLOW 0xAFE5#define PINK 0xF81F

Drawing Linestft.drawFastVLine(x,y,h,t);//drawFastVLine(int16_t x, int16_t y, int16_t h, uint16_t t)tft.drawFastHLine(x,y,w,t);//drawFastHLine(int16_t x, int16_t y, int16_t w, uint16_t t)tft.drawLine(xi,yi,xj,yj,t);//drawLine(int16_t x0, int16_t y0, int16_t x1, int16_t y1, uint16_t t)

drawLinefunction draws a line that starts in xi and yi locationends is in xj and yj and the color is t.for (uint16_t a=0; a<5; a++){ tft.drawFastVLine(x+a, y, h, t);}for (uint16_t a=0; a<5; a++){ tft.drawFastHLine(x, y+a, w, t);}for (uint16_t a=0; a<5; a++){ tft.drawLine(xi+a, yi, xj+a, yj, t);}for (uint16_t a=0; a<5; a++){ tft.drawLine(xi, yi+a, xj, yj+a, t);}

These three blocks of code draw lines like the previous code with 5-pixel thickness.tft.fillRect(x,y,w,h,t);//fillRect(int16_t x, int16_t y, int16_t w, int16_t h, uint16_t t)tft.drawRect(x,y,w,h,t);//drawRect(int16_t x, int16_t y, int16_t w, int16_t h, uint16_t t)tft.fillRoundRect(x,y,w,h,r,t);//fillRoundRect (int16_t x, int16_t y, int16_t w, int16_t h, uint8_t R , uint16_t t)tft.drawRoundRect(x,y,w,h,r,t);//drawRoundRect(int16_t x, int16_t y, int16_t w, int16_t h, uint8_t R , uint16_t t)

Drawing Circlestft.drawCircle(x,y,r,t); //drawCircle(int16_t x, int16_t y, int16_t r, uint16_t t)tft.fillCircle(x,y,r,t); //fillCircle(int16_t x, int16_t y, int16_t r, uint16_t t)

fillCirclefunction draws a filled circle in x and y location and r radius and t color.for (int p = 0; p < 4000; p++){ j = 120 * (sin(PI * p / 2000));i = 120 * (cos(PI * p / 2000));j2 = 60 * (sin(PI * p / 2000));i2 = 60 * (cos(PI * p / 2000));tft.drawLine(i2 + 160, j2 + 160, i + 160, j + 160, col[n]);}

Drawing Trianglestft.drawTriangle(x1,y1,x2,y2,x3,y3,t);//drawTriangle(int16_t x1, int16_t y1, int16_t x2, int16_t y2, int16_t x3, int16_t y3,// uint16_t t)tft.fillTriangle(x1,y1,x2,y2,x3,y3,t);//fillTriangle(int16_t x1, int16_t y1, int16_t x2, int16_t y2, int16_t x3, int16_t y3,// uint16_t t)

This code sets the cursor position to of x and ytft.setTextColor(t); //setTextColor(uint16_t t)tft.setTextColor(t,b); //setTextColor(uint16_t t, uint16_t b)

The second function just displays the string.showmsgXY(x,y,sz,&FreeSans9pt7b,"www.Electropeak.com");//void showmsgXY(int x, int y, int sz, const GFXfont *f, const char *msg)void showmsgXY(int x, int y, int sz, const GFXfont *f, const char *msg){ uint16_t x1, y1;uint16_t wid, ht;tft.setFont(f);tft.setCursor(x, y);tft.setTextColor(0x0000);tft.setTextSize(sz);tft.print(msg);}

This function changes the font of the text. You should add this function and font libraries.for (int j = 0; j < 20; j++) {tft.setCursor(145, 290);int color = tft.color565(r -= 12, g -= 12, b -= 12);tft.setTextColor(color);tft.print("www.Electropeak.com");delay(30);}

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.#include "Adafruit_GFX.h"#include "MCUFRIEND_kbv.h"MCUFRIEND_kbv tft;#include "Fonts/FreeSans9pt7b.h"#include "Fonts/FreeSans12pt7b.h"#include "Fonts/FreeSerif12pt7b.h"#include "FreeDefaultFonts.h"#define PI 3.1415926535897932384626433832795int col[8];void showmsgXY(int x, int y, int sz, const GFXfont *f, const char *msg){int16_t x1, y1;uint16_t wid, ht;tft.setFont(f);tft.setCursor(x, y);tft.setTextColor(0x0000);tft.setTextSize(sz);tft.print(msg);}void setup() {tft.reset();Serial.begin(9600);uint16_t ID = tft.readID();tft.begin(ID);tft.setRotation(1);tft.invertDisplay(true);tft.fillScreen(0xffff);showmsgXY(170, 250, 2, &FreeSans9pt7b, "Loading...");col[0] = tft.color565(155, 0, 50);col[1] = tft.color565(170, 30, 80);col[2] = tft.color565(195, 60, 110);col[3] = tft.color565(215, 90, 140);col[4] = tft.color565(230, 120, 170);col[5] = tft.color565(250, 150, 200);col[6] = tft.color565(255, 180, 220);col[7] = tft.color565(255, 210, 240);}void loop() {for (int i = 8; i > 0; i--) {tft.fillCircle(240 + 40 * (cos(-i * PI / 4)), 120 + 40 * (sin(-i * PI / 4)), 10, col[0]); delay(15);tft.fillCircle(240 + 40 * (cos(-(i + 1)*PI / 4)), 120 + 40 * (sin(-(i + 1)*PI / 4)), 10, col[1]); delay(15);tft.fillCircle(240 + 40 * (cos(-(i + 2)*PI / 4)), 120 + 40 * (sin(-(i + 2)*PI / 4)), 10, col[2]); delay(15);tft.fillCircle(240 + 40 * (cos(-(i + 3)*PI / 4)), 120 + 40 * (sin(-(i + 3)*PI / 4)), 10, col[3]); delay(15);tft.fillCircle(240 + 40 * (cos(-(i + 4)*PI / 4)), 120 + 40 * (sin(-(i + 4)*PI / 4)), 10, col[4]); delay(15);tft.fillCircle(240 + 40 * (cos(-(i + 5)*PI / 4)), 120 + 40 * (sin(-(i + 5)*PI / 4)), 10, col[5]); delay(15);tft.fillCircle(240 + 40 * (cos(-(i + 6)*PI / 4)), 120 + 40 * (sin(-(i + 6)*PI / 4)), 10, col[6]); delay(15);tft.fillCircle(240 + 40 * (cos(-(i + 7)*PI / 4)), 120 + 40 * (sin(-(i + 7)*PI / 4)), 10, col[7]); delay(15);}}

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.

tft lcd shield library brands

In this tutorial, you will learn how to use and set up 2.4″ Touch LCD Shield for Arduino. First, you’ll see some general information about this shield. And after learning how to set the shield up, you’ll see 3 practical projects.

The role of screens in electronic projects is very important. Screens can be of very simple types such as 7 Segment or character LCDs or more advanced models like OLEDs and TFT LCDs.

One of the most important features of this LCD is including a touch panel. If you are about to use the LCD, you need to know the coordinates of the point you touch. To do so, you should upload the following code on your Arduino board and open the serial monitor. Then touch your desired location and write the coordinates displayed on the serial monitor. You can use this coordination in any other project./*TFT LCD - TFT Touch CoordinateBased on Librery Examplemodified on 21 Feb 2019by Saeed Hosseinihttps://electropeak.com/learn/*/#include #include "TouchScreen.h"#define YP A2#define XM A3#define YM 8#define XP 9// For better pressure precision, we need to know the resistance// between X+ and X- Use any multimeter to read it// For the one we"re using, its 300 ohms across the X plateTouchScreen ts = TouchScreen(XP, YP, XM, YM, 300);void setup(void) {Serial.begin(9600);}void loop(void) {TSPoint p = ts.getPoint();if (p.z > ts.pressureThreshhold) {Serial.print("X = "); Serial.print(p.x);Serial.print("\tY = "); Serial.print(p.y);Serial.print("\tPressure = "); Serial.println(p.z);}delay(100);}

To display pictures on this LCD you should save the picture in 24bit BMP colored format and size of 240*320. Then move them to SD card and put the SD card in the LCD shield. we use the following function to display pictures. This function has 3 arguments; the first one stands for the pictures name, and the second and third arguments are for length and width coordinates of the top left corner of the picture.bmpdraw(“filename.bmp”,x,y);

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.

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.

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. It has way more resolution than a black and white 128x64 display. As a bonus, this display has a resistive touchscreen attached to it already, so you can detect finger presses anywhere on the screen.

This display shield has a controller built into it with RAM buffering, so that almost no work is done by the microcontroller. This shield needs fewer pins than our v1 shield, so you can connect more sensors, buttons and LEDs: 5 SPI pins for the display, another pin for the SPI touchscreen controller and another pin for uSD card if you want to read images off of it.

Now, I have bought 3.5" TFT LCD display for my Arduino Mega 2560 R3 to try whether I could run the screen or not, and it is not working now! I am so depressed and angry for these two"s misbehaviors. I have already checked website and a lot of Arduino IDE code examples and libraries such as UTFT.h, UTouch.h, UTFT_MEGA, UTFT_CTE, TFTLCD. I tried these and I can not run my 3.5" screen. Where am I faulty? There is something below the screen shield: www.mcufriend.com and 3.5" TFTLCD for Arduino 2560. Are there any basic code or have anyone tried to run Mcufriend"s displays correctly?

There are a few common TFT display drivers on the electronics hobbyist market, and a handful of libraries that work with them. TFT displays are high resolution and full color, unlike the OLED or ePaper displays mentioned in this repository. Most libraries for color TFT displays implement the usual 24-bit RGB color space, where 0xFF0000 is red, 0x00FF00 is green, and 0x0000FF is blue.

TFT displays can be slow to update. Therefore, it’s sometimes usefil to draw only part of the display at once. Adafruits GFX library includes a Canvas class, which lets you update elements offscreen and then draw them. It doesn’t speed up the display, but it can simplify drawing a subset of the screen. See this example to see it in use. Other libraries don’t include a canvas, but you can draw a filled rectangle over part of the screen and then draw on top of it, as shown in this example for the ILI9225.

Most TFT displays tend to have an SPI interface, with some extra pins, as explained on the main page of this repo. Some displays, like MakerFocus’ 1.3” TFT, do not implement the CS pin. For this board and others like it, initializing them with SPI_MODE3 works.

All of the displays listed below have been tested with the Adafruit_ST7735/ST7789 libraries and the Adafruit_GFX library, with the modifications mentioned below.

MakerFocus 1.3” LCD Display, no MicroSD, Amazon link - This display does not have a CS pin, so it can’t be used with other SPI devices at the same time. It works with the Adafruit_ST7789 library, but you have to change the init() function to include the SPI mode like so:

There’s no standard library for TFT screens, unfortunately. Vendors tend to support the displays they make in their own breakout boards, and not others. As with other types of displays, a well-supported library like the Adafruit libraries makes the display worth more, but limits you to the types of displays that vendor offers. Display manufacturers like Ilitek and Sitronix do not appear to release their own libraries for their displays.

The Adafruit_ST7735/7789 library and Adafruit_GFX library works well with some of the Sitronix boards above. It does not support the DFRobot ST7867S board, however.

The DFRobot_ST7687S library has slow refresh rate on the ST7687S board. It’s unclear whether the issue is the library or the board, however. I have yet to find another library to use with this display, though there are a couple other vendors for the board itself on Amazon. Unfortunately the u8g2 library doesn’t support this display, though it does support many of the Sitronix boards.

The TFT_22_ILI9225 library works with this display, and its methods are well documented. Its graphics API is different than some of the other graphics libraries, and doesn’t implement the Printable API, so you can’t use commands like print() and println() with it. It has its own drawText() method instead, which takes an Arduino String object. It comes with a few built-in fonts, and includes many of the Adafruit GFX fonts, and you can generate your own fonts using the The squix.ch custom font generator. Set the settings to
