arduino tft lcd gui pricelist

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:

I am so keen about getting this project up but most information i searched online are very old and could not provide any assistance. This project is based on a touch screen display and i will be forever indebted to all help i get here. Forgive me but am a complete noob into arduino coding but i need this important project done. Please help guys.

*After the Arduino is Turned ON,we should be greeted with homescreen showing message "Xtreme Rework Station V3", with below buttons to SELECT PROFILE, RUN SELECTED PROFILE and SETTINGS.

**Use sliders styling to input numbers on the touchscreen during settings. (since the screen is touchscreen,its difficult to type numbers manually), physical press buttons on arduino board can also be used .

Very important also, When click RUN SELECTED PROFILE ,the Touchscreen LCD to show the profile status running as a graphical curve/histogram chart in real-time showing the current stage running, the SET TEMP and CURRENT TEMP for both Top Heater and Bottom Heater separately. Visit Zallus Reflow Controller Quick Initial Run - YouTube to see example of how i want the graph to work like.

Included GUI Design Software Makes Programming Fast & Easy -Our HMI TFT LCD module is a whole display system that comes with no-cost GUI design software(STONE Designer).

Displaying a custom image or graphic on a LCD display is a very useful task as displays are now a premium way of providing feedback to users on any project. With this functionality, we can build projects that display our own logo, or display images that help users better understand a particular task the project is performing, providing an all-round improved User Experience (UX) for your Arduino or ESP8266 based project. Today’s tutorial will focus on how you can display graphics on most Arduino compatible displays.

The procedure described in this tutorial works with all color displays supported by Adafruit’s GFX library and also works for displays supported by the TFTLCD library from Adafruit with little modification. Some of the displays on which this procedure works include:

While these are the displays we have, and on which this tutorial was tested, we are confident it will work perfectly fine with most of the other Arduino compatible displays.

For each of the displays mentioned above, we have covered in past how to program and connect them to Arduino. You should check those tutorials, as they will give you the necessary background knowledge on how each of these displays works.

For this tutorial, we will use the 2.8″ ILI9325 TFT Display which offers a resolution of 320 x 340 pixels and we will display a bitmap image of a car.

To demonstrate how things work, we will use the 2.8″ TFT Display. The 2.8″ TFT display comes as a shield which plugs directly into the Arduino UNO as shown in the image below.

Not all Arduino displays are available as shields, so when working with any of them, connect the display as you would when displaying text (we recommend following the detailed tutorial for the display type you use of the above list). This means no special connection is required to display graphics.

Before an image is displayed on any of the Arduino screens, it needs to be converted to a C compatible hex file and that can only happen when the image is in bitmap form. Thus, our first task is to create a bitmap version of the graphics to be displayed or convert the existing image to a bitmap file. There are several tools that can be used for creation/conversion of bitmap images including, Corel Draw and Paint.net, but for this tutorial, we will use the Paint.net.

Your graphics could also include some text. Just ensure the background is black and the fill color is white if you plan to change the color within your Arduino code.

Image2Code is an easy-to-use, small Java utility to convert images into a byte array that can be used as a bitmap on displays that are compatible with the Adafruit-GFX or Adafruit TFTLCD (with little modification) library.

Paste the bit array in the graphics.c file and save. Since we have two graphics (the car and the text), You can paste their data array in the same file. check the graphics.c file attached to the zip file, under the download section to understand how to do this. Don’t forget to declare the data type as “const unsigned char“, add PROGEM in front of it and include the avr/pgmspace.h header file as shown in the image below.  This instructs the code to store the graphics data in the program memory of the Arduino.

With this done, we are now ready to write the code. Do note that this procedure is the same for all kind of displays and all kind of graphics. Convert the graphics to a bitmap file and use the Img2code utility to convert it into a hex file which can then be used in your Arduino code.

To reduce the amount of code, and stress involved in displaying the graphics, we will use two wonderful libraries; The GFX library and the TFTLCD library from Adafruit.

The Adafruit libraries do not support all of the displays but there are several modifications of the libraries on the internet for more displays. If you are unable to find a modified version of the library suitable for your the display, all you need do is copy the code of the drawBitmap() function from the GFX library and paste it in the Arduino sketch for your project such that it becomes a user-defined function.

The first two are thex and y coordinates of a point on the screen where we want the image to be displayed. The next argument is the array in which the bitmap is loaded in our code, in this case, it will be the name of the car and the text array located in the graphics.c file. The next two arguments are the width and height of the bitmap in pixels, in other words, the resolution of the image. The last argument is the color of the bitmap, we can use any color we like. The bitmap data must be located in program memory since Arduino has a limited amount of RAM memory available.

As usual, we start writing the sketch by including the libraries required. For this procedure, we will use the TFTLCD library alone, since we are assuming you are using a display that is not supported by the GFX library.

Next, we specify the name of the graphics to be displayed; car and title. At this stage, you should have added the bit array for these two bitmaps in the graphics.c file and the file should be placed in the same folder as the Arduino sketch.

The last section of the code is the drawBitmap function itself, as earlier mentioned, to use the drawbitmap() function with the Adafruit TFTLCD library, we need to copy the function’s code and paste into the Arduino sketch.

Plug in your screen as shown above. If you are using any other display, connect it as shown in the corresponding linked tutorial. With the schematics in place, connect the Arduino board to your PC and upload the code. Don’t forget the graphics file needs to be in the same folder as the Arduino sketch.

That’s it for this tutorial guys. The procedure is the same for all kinds of Arduino compatible displays. If you get stuck while trying to replicate this using any other display, feel free to reach out to me via the comment sections below.

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.
