open smart tft lcd shield library quotation

Specifically the "2.4 inch UART Serial TFT LCD module Touch Screen Expansion Shield with TF card socket Touch Pen for Arduino UNO R3 Mega2560 Nano" from Aliexpress. Once you power it up it identifies itself as an "Open Smart TFT LCD".

Recently I bought TFT 2.2" RM68130 OPEN SMART. I tried all that Impulsive said here on this thred (use SUPPORT _9225 & USE_OPENSMART_SHIELD_PINOUT, forced begin(0x9225))

In this Arduino touch screen tutorial we will learn how to use TFT LCD Touch Screen with Arduino. You can watch the following video or read the written tutorial below.

The third example is a game. Actually it’s a replica of the popular Flappy Bird game for smartphones. We can play the game using the push button or even using the touch screen itself.

As an example I am using a 3.2” TFT Touch Screen in a combination with a TFT LCD Arduino Mega Shield. We need a shield because the TFT Touch screen works at 3.3V and the Arduino Mega outputs are 5 V. For the first example I have the HC-SR04 ultrasonic sensor, then for the second example an RGB LED with three resistors and a push button for the game example. Also I had to make a custom made pin header like this, by soldering pin headers and bend on of them so I could insert them in between the Arduino Board and the TFT Shield.

Here’s the circuit schematic. We will use the GND pin, the digital pins from 8 to 13, as well as the pin number 14. As the 5V pins are already used by the TFT Screen I will use the pin number 13 as VCC, by setting it right away high in the setup section of code.

I will use the UTFT and URTouch libraries made by Henning Karlsen. Here I would like to say thanks to him for the incredible work he has done. The libraries enable really easy use of the TFT Screens, and they work with many different TFT screens sizes, shields and controllers. You can download these libraries from his website, RinkyDinkElectronics.com and also find a lot of demo examples and detailed documentation of how to use them.

After we include the libraries we need to create UTFT and URTouch objects. The parameters of these objects depends on the model of the TFT Screen and Shield and these details can be also found in the documentation of the libraries.

So now I will explain how we can make the home screen of the program. With the setBackColor() function we need to set the background color of the text, black one in our case. Then we need to set the color to white, set the big font and using the print() function, we will print the string “Arduino TFT Tutorial” at the center of the screen and 10 pixels  down the Y – Axis of the screen. Next we will set the color to red and draw the red line below the text. After that we need to set the color back to white, and print the two other strings, “by HowToMechatronics.com” using the small font and “Select Example” using the big font.

As you know OPEN-SMART TFT display is a shield-type display for Arduino UNO and Mega. So The pin configurations are pre-fixed and can’t be changed. Download the modified MCUFRIEND_kbv Arduino library for using the TFT display and the TouchScreen library for controlling the touch screen.

From the above picture, we can see an LM75 temperature sensor on the back of the TFT display. Download the LM75 library from GitHub for using the LM75 temperature sensor provided in the TFT shield.

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).

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!

The display demand for every project is unique, a project may require just a simple, single character OLED display, while another project may require something bigger, all based on the function the display is to perform. For this reason, as a maker or electronics hobbyist, anyone needs to know how to work with as many displays as possible, that’s why today, we will take a look at how to use the super cheap, 3.2″ color TFT display with Arduino.

For this tutorial, we will use the 3.2″ TFT display from banggood. The display which is based on the HX8357B LCD Controller, supports 16-wire DataBus interface and comes with 262K color at 480 x 320 resolution. The module includes an SD card socket, an SPI FLASH circuit and a 5V-3.3V power and Logic Level conversion circuit which makes it easy to use with any microcontroller that uses either 5v or 3.3v  logic voltage level. The module can be directly inserted into an Arduino Mega or Due board.

To demonstrate how the display works, we will use the UTFT LCD library for Arduino to display some images and text on the display including an animated graph. All these will show how the display could be used for something like an oscilloscope.

These components can each be bought via the links attached. The 3.2″ TFT display, as at the time I bought it was listed on the website as a 3″ display but after buying and measuring, the size of the display is 3.2″.

The display comes in a shield form, which means it can be plugged directly into the Arduino with which it is going to be used, as such, no schematic is needed. Plug the display into your Arduino Mega or Due as shown in the image below.

To achieve the goals of this tutorial, we will use a simple sample code attached to the UTFT library. The UTFT library is a library created to facilitate easy interaction between a microcontroller and several LCD displays. Unfortunately, the latest versions of the UTFT library has no support for the HX8357B LCD controller which is used to our 3.2″ TFT display. To go round this hurdle, we will be installing a previous version of the library on the Arduino IDE.

The wonderful library written by Henning Karlsen can be downloaded from the link below. The libraries are pre-built for each Arduino board so choose the right one that matches the board you are using from the link below.

Use your favorite library installation method to install the library after downloading and launch an Instance of the Arduino IDE. With the IDE opened, click on file, select examples, select UTFT then select the Display Demo or the UTFT_Demo_480x320 example.

We will attempt to do a brief explanation of the code. The code starts by setting the speed (the wait variable) at which it runs to 2000. This speed can be reduced to zero so the demo can play slowly. After this, we include the utft library and invoke the custom library for the for Arduino Due.

Next, we specify the initial color for the fonts to be used. It should be noted that to use custom fonts, they must be pre-loaded into the library by editing the User_Setup.h file in the library.

with that done, we proceed to the void setup() function. Under the setup() function, we initialize the LCD using the init command and we ensure the LCD display is on landscape using the set rotation function with a value of 1.

Spice up your Arduino project with a beautiful small display shield . This TFT display is small (1.8" diagonal) bright (4pcs white-LED chips) and colorful (18-bit 262,000 different shades)! 128x160 pixels with individual pixel control.

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.

The code is written for Arduino but can be easily ported to your favorite microcontroller!

This is a 3.2 inch TFT touch screen expansion board using standard Shield interface and it has good compatibility. It integrates a 3.2-inch touch screen, I2C temperature sensor, TF card holder, level conversion circuit, and the secondary development is easy.IF with GPRS module, you can design your Arduino phone. IF with NFC reader module, you can create access control systems with the photos show. IF with voltage and current sensor, you can make oscilloscope.

Begin by carefully starting the rear connector of the TFT shield onto the Arduino Uno/Mega. Go slowly and ensure that all pins are inserted correctly and are straight.

In order to use 3.2″ TFT lcd  Shield , We must have the libraries. So you can download  Adafruit-GFX-Library and MCUFRIEND kbv install the library by extracting that zipped file in the library folder as shown below.

Open  the folder “MCUFRIEND_kbv” into your directory: “C:\Program Files (x86)\Arduino\libraries” , And Open MCUFRIEND_kbv H file . To do some minor edits to H file you can use Notepad++ download it here.
