arduino 3.5 tft lcd shield code in stock

Spice up your Arduino project with a beautiful large touchscreen display shield with built in microSD card connection. This TFT display is big (3.5" diagonal) bright (6 white-LED backlight) and colorful (18-bit 262,000 different shades)! 320x480 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 FT6236 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 pin32 (SDO) of 3.5 display module is also used by touch panel or SD card SPI interface, so we must cut off this pin to avoid conflict with the touch panel or SD card.

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 (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!

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.

I purchased a shield with the description 3.5" TFT LCD Shield for Arduino Uno/Mega (ILI9481) recently from here 3.5" TFT LCD Shield for Arduino Uno/Mega (ILI9481) - Electronics Display LCD Graphic - Boxtec Onlineshop.

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.

How project worksThe code fills a rectangle, then draws a rectangle within which text “EEWORLDONLINE” is displayed. Then, lines, circles, rectangles, and squares are drawn on the screen. The project ends with a greeting and a message.

Note: The following picture is the connection diagram of the 2.8-inch TFT screen and Arduino uno, but this product is connected in exactly the same way.

If the Arduino board has an ICSP interface, set the SPI Config switch on the display module to the ICSP direction (by default) (the company"s Arduino UNO motherboard has an ICSP interface, just plug it in directly.).

This product uses the same LCD control chip and touch panel control chip as the 3.5-inch TFT screen of the same series of our company, so the code is completely compatible. The following takes 3.5-inch TFT as an example to introduce.

LCD_Show can display colorful patterns with different shapes and times. LCD_ShowBMP is for displaying the picture in BMP, and LCD_Touch is for using the touching function.

The display controller used in this product is ILI9486, and we need to initialize the controller through the SPI communication protocol, and the initialization functions are written in LCD_Driver.cpp.

The function functions related to the screen display are written in LCD_GUI.cpp. The function of each function and the parameters passed are explained in the source code. You can call it directly when you need to use it.

Before using LCD_ShowBMP to display pictures, first copy the pictures in the PIC folder in the data to the root directory of the SD card (you should understand that in the root directory, that is to save the pictures directly to the SD card, do not put them in any subfolders folder.).

These functions are all written in LCD_Bmp.cpp. In fact, the image data in BMP format with a specific file name is read from the SD card, and then the display function written by us is called to re-express the data as an image.

No matter which platform this method is on, the principle is similar. Interested friends can check the relevant information and study the relevant code carefully.

In fact, you can also use Image2Lcd image modulo software to convert images of different sizes and formats into array data, and then use the functions we wrote to display them.

Note: The following picture is the connection diagram of the 2.8-inch TFT screen and XNUCLEO-F103RB, but this product is connected in exactly the same way.

The demos are developed based on the HAL library. Download the program, find the STM32 program file directory, and open STM32\XNUCLEO-F103RB\lcd4in-demo\MDK-ARM\ lcd4in-demo.uvprojx.

This product uses the same LCD control chip and touch panel control chip as the 3.5-inch TFT screen of the same series of our company, so the code is completely compatible. The following takes 3.5-inch TFT as an example to introduce.

After running the demo, it displays some characters and patterns at first, then displays four pictures, and finally displays the touch sketchpad function. Actually, three projects in the Arduino platform code are integrated in the main function, we place the three main functions in sequence and place TP_DrawBoard(); in an infinite loop to achieve the above functions.

Before using LCD_ShowBMP to display pictures, copy the pictures in the PIC folder in the data to the root directory of the SD card, and then insert the SD card into the SD card slot on the back of the screen to start the download program verification.

In fact, you can also use Image2Lcd image modulo software to convert images of different sizes and formats into array data, and then use the functions we wrote to display them.
