3.5 tft lcd for arduino uno library supplier

i read that the screen consumes a lot of power and i observed that arduino is more hot than it should, so i dont know if there is something i can do about it or it will damage it long term. i guess the best solution is to bypass the power pin and use external power supply with enough current available.

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.

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 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);}

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.#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 LCDs are the most popular color displays – the displays in smartphones, tablets, and laptops are actually the TFT LCDs only. There are TFT LCD shields available for Arduino in a variety of sizes like 1.44″, 1.8″, 2.0″, 2.4″, and 2.8″. Arduino is quite a humble machine whenever it comes to process or control graphics. After all, it is a microcontroller platform, and graphical applications usually require much greater processing resources. Still, Arduino is capable enough to control small display units. TFT LCDs are colorful display screens that can host beautiful user interfaces.

Most of the smaller TFT LCD shields can be controlled using the Adafruit TFT LCD library. There is also a larger TFT LCD shield of 3.5 inches, with an ILI9486 8-bit driver.

The Adafruit library does not support the ILI9486 driver. Actually, the Adafruit library is written to control only TFT displays smaller than 3.5 inches. To control the 3.5 inch TFT LCD touch screen, we need another library. This is MCUFRIEND_kbv. The MCUFRIEND_kbv library is, in fact, even easier to use in comparison to the Adafruit TFT LCD library. This library only requires instantiating a TFT object and even does not require specifying pin connections.

TFT LCDs for ArduinoUser interfaces are an essential part of any embedded application. The user interface enables any interaction with the end-user and makes possible the ultimate use of the device. The user interfaces are hosted using a number of devices like seven-segments, character LCDs, graphical LCDs, and full-color TFT LCDs. Out of all these devices, only full-color TFT displays are capable of hosting sophisticated interfaces. A sophisticated user interface may have many data fields to display or may need to host menus and sub-menus or host interactive graphics. A TFT LCD is an active matrix LCD capable of hosting high-quality images.

Arduino operates at low frequency. That is why it is not possible to render high-definition images or videos with Arduino. However, Arduino can control a small TFT display screen rendering graphically enriched data and commands. By interfacing a TFT LCD touch screen with Arduino, it is possible to render interactive graphics, menus, charts, graphs, and user panels.

Some of the popular full-color TFT LCDs available for Arduino include 3.5″ 480×320 display, 2.8″ 400×200 display, 2.4″ 320×240 display and 1.8″ 220×176 display. A TFT screen of appropriate size and resolution can be selected as per a given application.

If the user interface has only graphical data and commands, Atmega328 Arduino boards can control the display. If the user interface is a large program hosting several menus and/or submenus, Arduino Mega2560 should be preferred to control the TFT display. If the user interface needs to host high-resolution images and motions, ARM core Arduino boards like the DUE should be used to control the TFT display.

MCUFRIEND_kbv libraryAdafruit TFT LCD library supports only small TFT displays. For large TFT display shields like 3.5-inch, 3.6-inch, 3.95-inch, including 2.4-inch and 2.8-inch TFT LCDs, MCUFRIEND_kbv library is useful. This library has been designed to control 28-pin TFT LCD shields for Arduino UNO. It also works with Arduino Mega2560. Apart from UNO and Mega2560, the library also supports LEONARDO, DUE, ZERO, and M0-PRO. It also runs on NUCLEO-F103 and TEENSY3.2 with Sparkfun Adapter. The Mcufriend-style shields tend to have a resistive TouchScreen on A1, 7, A2, 6 but are not always in the same direction rotation. The MCUFRIEND_kbv library can be included in an Arduino sketch from the library manager.

The 3.5-inch TFT LCD shield needs to be plugged atop the Arduino board. The Mcufriend-style shields are designed to fit into all the above-mentioned Arduino boards. The shields have a TFT touch screen that can display colorful images and interfaces and a micro SD card reader to save images and other data. A 3.5-inch TFT LCD touch screen has the following pin diagram.

Spice up your Arduino project with a beautiful large touchscreen display shield with built in microSD card connection. This TFT display is big (3.2" diagonal) bright (5 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.

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).

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!

If you"ve had a lot of Arduino DUEs go through your hands (or if you are just unlucky), chances are you’ve come across at least one that does not start-up properly.The symptom is simple: you power up the Arduino but it doesn’t appear to “boot”. Your code simply doesn"t start running.You might have noticed that resetting the board (by pressing the reset button) causes the board to start-up normally.The fix is simple,here is the solution.

This module is a 3.5-inch TFT LCD module with “320X480” resolution and 65K color display. It is suitable for Arduino Uno and Mega2560 development boards, and also supports SD card expansion function. It uses 8-bit parallel port communication, and the driver IC is ILI9486.

The 3.5-inch display is a ready-made shield for Arduino Uno, which can also be placed on the Arduino Mega. The pins of this shield are designed to be easily installed on the Arduino. The bad point about these modules is that they use all Arduino Uno pins.
