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.

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.

In order the code to work and compile you will have to include an addition “.c” file in the same directory with the Arduino sketch. This file is for the third game example and it’s a bitmap of the bird. For more details how this part of the code work  you can check my particular tutorial. Here you can download that file:

One of the major benefits of using this display is its compatibility with the STONE TOOL GUI Designer which allows the development of User Interfaces in a fast and easy manner.

To demonstrate the capabilities of the display, we will build a heart rate monitor using an Arduino Uno with the MAX30100 pulse oximetry and heart rate sensor. The Arduino will serve as the brain of the project and perform the simple task of obtaining the heart rate and blood oxygen data from the MAX30100, displaying it on the screen.

At the end of this tutorial, you would know how to interface Arduino boards with the STONETech displays, and also how to interface sensors like the MAX30100 with the Arduino.

Our development process for today’s project will follow this outline. We will first create the GUI for the project after which we will proceed to write the firmware to interface the microcontroller with the display.

There are two major ways of creating a GUI. One is to create the GUI using only the elements (buttons, text boxes, etc) that are available within the GUI Design tool, while the second is to create a mockup image using image editing tools like Photoshop/Paint.NET, import the image into the GUI Desing tool software and place the GUI design elements on the image. For this tutorial, we will go with the second option as it allows more flexibility and gives room for the development of truly beautiful GUIs.

As mentioned during the introduction, today’s tutorial will focus on creating a heart rate and Oxygen-level monitoring system using the display and to get things started, we create the GUI image (shown below) using Photoshop.

With the GUI Image done, we then proceed to import it into the STONE TECH GUI tool. This obviously mean we need to install the STONE TOOL first, so head over to the STONE Tool GUI Designer page and download it. The STONE TOOL software requires no installation and it can be directly opened and run by decompression on your computer.

4. Next, we add fonts to the project’s assets to determine how texts appear on the display. Right-click the “Font” file, and select the appropriate font to add to the project. For this tutorial, we will use the ASCII 24 by 48 font. With that done we are now ready to begin adding the GUI elements.

5. We will only use the “Text Display” GUI element since the display is only meant to display data from the MAX30100. The text display elements are capable of holding texts that can be changed programmatically by updating the data stored in their memory addresses. Add text displays on the lines as highlighted in the image below. Also, create a text display for the day-time section at the top of the display image to help users note the date/time each reading was observed.

6. Next, we set the properties of the text displays especially their memory addresses. The properties of each GUI element will be available on the right-hand side of your PC screen after clicking on the element. Note the memory address down as it will play an important role later.

7. With all of these done, we compile the GUI and upload it to the screen. To do this, click on button 1 in the image below to Compile the GUI design and click on button 2 to upload the GUI to your display.

Uploading the GUI display requires you either connect the display directly to your computer or you put the GUI on a flash drive and plug the flash drive into the USB port of the display. Because of the little complexity associated with the second option, we will be going with it.

Plug the USB flash drive into the computer then click the “Download to u-disk” button on the STONE GUI TOOL.With the “download to u-disk” process complete, pull out the USB flash disk, insert it into the USB interface of the display module and wait for the completion of the upgrade. When the upgrade is completed, there will be a prompt sound.

The model of the STONE display being used for this tutorial communicates via RS232, as such, to be able to interface the display with the Arduino, we have to connect it through a MAX3232 chip. This extra requirement can be avoided by using one of the STONE displays with a TTL interface.

Go over the connections once again to be sure everything is properly connected. With this done we can now proceed to the Arduino code to send commands and data to the LCD.

Due to the simplicity embedded in the design of STONETECH displays, the microcontroller’s interaction with any of the GUI components is usually via the “memory address” of each component. for instance, to send a message to the display from the microcontroller (the Arduino in this case), the message has to be published to the memory address of the GUI Component (in this case, the text-display component). The same holds for GUI Components that are meant to send data to the microcontroller, as the microcontroller has to poll their memory address to obtain information from them. As a result of these, we need to obtain the memory address of all the GUI components before proceeding. For each GUI component, the memory address is usually listed among the properties of the component, under the property toolbar, at the right-hand side of the STONE TOOL interface.

With this obtained, we can now proceed to write the code for the project. One of the good things about using the STONETech displays is the fact that you don’t need a library to write code for them because of their simplicity, but since we will use serial communication, we will use the software serial library to avoid having to use the hardware serial port on the Arduino Uno. To interface with the MAX30100, we will also need to install the MAX30100 library. The Max30100 library can be installed using the Arduino Library Manager or by downloading it from the attached link and installing manually by extracting the file, copying its content and pasting it in the Arduino libraries folder. The software serial library comes pre-installed with the Arduino IDE.

>With the libraries installed, we now have all we need to write the Arduino Code. As usual, I will do a brief explanation and attach the complete version of the code under the download section.

We start the function by initializing serial communications between the screen and the microcontroller setting the baud rate to 115200. We also initialize hardware serial communication so we can use the serial monitor on the Arduino IDE for debugging purposes.

With the code complete, connect your Arduino board to your computer and upload the code to your setup. Place a finger on the Max30100 and after a while, you should see the live pulse rate and oxygen levels appear on the display as shown in the image below.

While this project only demonstrates less than 35% of the capabilities of the STONE TECH display, it provides a good foundation for you to build amazing projects. As an engineer, the key benefit of the display to me is the ease of use both in the creation of the GUI and also the development of the code to tie it together with a microcontroller. The fact that the display doesn’t require any library makes it perfect for use with any language and any microcontroller with serial port access.

I recently purchased a touch screen module to go with my Arduino Mega 2560. The demo documentation was easy enough to follow, I uploaded a TFTpaint program demo, the GLUE demo, as well as a mock phone dialer program. My initial hopes were to utilize some drawing utilities in conjunction with the needed touch libraries in order to create a custom GUI for an automation project I am working on. Over the last couple of nights I have been exploring different display driver libraries for the Arduino and it would seem that GUIslice is exceptionally well-designed. However, there is no native support for my LCD. I am quite new to modifying source code and attempting to configure the library file correctly to match my screen has proven to be a challenge.

I will include the sample files for my LCD screen. This will provide information regarding library supports required to drive the display. Also, I will present all library files which I believe are necessary to drive the display, including the required raw GUIslice library files which must be configured accordingly to hardware of my LCD Screen. I will include a photo of the back of the module with the pins and descriptors as well. Lastly, I will provide the modified library files which I have edited to try and interface with the pins of my LCD screen and the GPIOs of my MEGA board.

These are all the modified files and needed libraries to run MY LCD. There is a sketch included that should have all config.h aspects modified as needed to drive my display:

After studying some of the test results of different models and settings provided via an Excel doc located at the bottom of this post, I looked at the source code for the libraries used in driving myLCD examples to find that Adafruit_TFTLCD.h is called to within the driver layer for Adafruit-GFX of GUIslice_drv_adagfx.cpp

I know that it can be driven using the Adafruit_TFTLCD.h library. and Adafruit_GFX.h library. --both of which are embedded in GUIslice-- srcTouchScreen.h is also called out in myLCD example code but I do not recall whether it is embedded in GUIslice through reference in GUIslice.h

Presently, I don"t have time to dig into this further. Working a lot and doing family. I would like to avoid purchasing a new display simply so that it is out-of-the-box compatible with GUIslice when I know that myLCD can be configured with the application. the GUIslice Builder cross-platform app looks incredible and I have already utilized it as a way to speed up the process of compiling code to my device. Adding support for this display could open the doors up for a lot of new development using GUIslice on other screens with the same hardware and pinout. My experience is currently limited and I would not be able to create a GUI so quickly were it not for the help of GUIslice. This platform is going to become my mainstay for navigating the user interface of my project. If nothing else, someone please help send me in the right direction. I have been through these files enough that my head is spinning and I"m at a loss for progress. SD access is not imperative, however, touch and graphic support are. Currently, my screen is white when the code compiles. I can only assume that something is not correct with the configuration files and I just feel as though I"ve been chasing my tail.

The NXP LPC55S69-EVK is a versatile board. In this article I show how it can be used with Adafruit TFT LCD boards, both with resistive and capacitive touch. For the software I’m using the open source LittlevGL GUI.

Both the capacitive and resistive Adafruit LCD boards are using the popular ILI9341 display controller. On the resistive version, the STMPE610 (SPI) touch controller is used. On the capacitive version the FT6206 (I2C) is present.

The Adafruit ILI9341 based touch displays are a great and easy way to extend a board like the NXP LPC55S69 with a state-of-the art open source GUI library. The project presented here supports both the capacitive and resistive touch displays from Adafruit.

Welcome. In this post, I will introduce you my Lightweight Arduino GSM Mobile phone. The lightweight mobile is capable of the following National/International features:Make Calls

I also used a display to visualize GUI interfaces, I selected an LCD touch display by Nextion, trust me it is really an awesome display. Nextion adopts a new and easy way to interface any of your projects through UART. Its easy-to-use configuration software (Nextion Editor) allows you to design your own interfaces using GUI commands and makes the pieces of your development effortless, in turn you can save lots of program space in your MCUs. Thanks to Nextion!

On its own, the GSM module and the Nextion touch display can’t do anything. It requires a microcontroller to drive it. At the heart is an Arduino Uno to drive the lightweight GSM Mobile phone, which can send and receive commands over its RX/TX pins.

If you are interested making yours, this guide will show you how to build and upload the source codes to get your project up and running. This is a fairly straightforward project, but an intermediate one especially when you take into account the complexity of the codes.

This project is also a great example of how to use Arduino especially for string & character handling, as well as for you to get acquainted with the new Nextion TFT Intelligent LCD Touch Display and using AT commands for the GSM module. Hope you will enjoy and find my post interesting. Now let us make it.

In this project, I used 8 pages to make the interactive GUI. Most of the icons which I used for the implementation are the freely available Android Icons and can be downloaded from this [link]. I used paint.net (Open Source editor) to edit/resize all the pictures and to create the invert of the icons, to give the feeling of touch when components like buttons are pressed. Touch events like (Press & Release) are also included when components are touched. If you are interested to acquire more about Nextion Instruction Set you can visit the wiki page here.

To get the complete code, simply scroll down to find my GitHub repository section of this page. Copy the code, and paste it into a new sketch in the Arduino IDE. Save it, upload it to your Arduino.

because i am going to order arduino uno in pcb along with some pcbs and wanted to make some more projects soon. and the code below please check it out friends.
