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 has only graphical data and commands, Atmega328 Arduino boards can control the display. A TFT screen of appropriate size and resolution can be selected as per a given application. 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. By interfacing a TFT LCD touch screen with Arduino, it is possible to render interactive graphics, menus, charts, graphs, and user panels. However, Arduino can control a small TFT display screen rendering graphically enriched data and commands. That is why it is not possible to render high-definition images or videos with Arduino.
A TFT LCD is an active matrix LCD capable of hosting high-quality images.Īrduino operates at low frequency. A sophisticated user interface may have many data fields to display or may need to host menus and sub-menus or host interactive graphics. Out of all these devices, only full-color TFT displays are capable of hosting sophisticated interfaces. The user interfaces are hosted using a number of devices like seven-segments, character LCDs, graphical LCDs, and full-color TFT LCDs. The user interface enables any interaction with the end-user and makes possible the ultimate use of the device. User interfaces are an essential part of any embedded application.
The 3.5 inch TFT LCD can be used for a number of applications like – If you are not using an Arduino-shaped microcontroller, check out our 2.8" TFT breakout board which can be easily wired up to any processor the breakout board version does not have microSD holder.MCUFRIEND TFT LCD Touch Screen Shield on Arduino UNO
2.8TFT ARDUINO LCD LIBRARY CODE
The code is written for Arduino but can be easily ported to your favorite microcontroller! We also have a touch screen library that detects x, y and z (pressure) and example code to demonstrate all of it.
2.8TFT ARDUINO LCD LIBRARY FULL
Of course, we wouldn't just leave you with a datasheet and a "good luck!" - we've written a full open source graphics library that can draw pixels, lines, rectangles, circles and text. The shield does require a lot of pins: 12 lines total for the display, 13 total if you use the microSD card
This display shield has a controller built into it with RAM buffering, so that almost no work is done by the microcontroller. This shield does work with the Mega Arduinos but its going to be half the speed of the Uno-type boards because of the way the Mega rearranges all the pins (there is no way to get around this!) This shield is not Leonardo-compatible 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/Duemilanove/Diecimila). The shield is fully assembled, tested and ready to go. As a bonus, this display has a resistive touchscreen attached to it already, so you can detect finger presses anywhere on the screen. It has way more resolution than a black and white 128圆4 display. 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. Spice up your Arduino project with a beautiful large touchscreen display shield with built in microSD card connection.
