STONE provides customers with Intelligent HMI solutions. The intelligent TFT LCD module with a Cortex-M4 32-bit CPU can be controlled by any MCU via simple Hex Instruction through the UART port.

STVA151WT-01 TFT LCD module consists of a CPU, TFT drives, flash memory, UART port, power supply, etc. STONE also provides a basic control program and powerful design software (STONE TOOL Box). You can use it to set various functions on the graphical user interface, such as text, figures, curve, image switching, keyboard, progress bar, the slider, dial-up, clock and touch button, data storage, the USB download, video, and audio.

It isvery easy for engineers to develop the TFT-LCD color user interface and touch control functions, which can reduce a lot of development time and cost.

1. Create a graphic user interface (GUI). We will provide you a very powerful and simple GUI design software—STONE TOOL Box. You can use it to create your own interface by using any.jpg/.bmp format image.

2. Assign the different variable memory addresses for the different function block-like data display, text display, or variable icons, to make sure the variable value can be stored and assigned.

The following tutorial shows you how to use the STONE STVC050WT-01 touch display module to make a simple home appliance control system. STONE STVC050WT-01 the support touch display module is 5 inches, 480 * 272 resolution on the module has been integrated display and touch screen driver needed chips, developers need only on the STONE, the official VGUS design software related UI interface design and generate a programming file downloaded to the STONE display module, and then through a serial port (RS232 / RS485 / TTL) correspond with it, you can perform complex UI design aspects.

This display module is just one of many in this line of products. There are many other display modules available in different configurations. www.stoneitech.com

2. MCU communicates with STONE display module through serial port. 3. The MCU performs other actions based on the data obtained in step 2. UI interface design: Today we made a simple home appliance control. Through Photoshop, I designed the following simple interface:

when the light button is pressed, the page jumps to 2, showing the switch state of three lights.When the on/off light button is pressed, the serial port of the screen module issues the switch signal protocol.The external MCU can send data directly to the screen module through a serial port. Let the screen display the light switch state directly.

https://www.stoneitech.com/support/download/softwa... STONE TOOL is a GUI design software that requires no installation. After downloading, it can be directly opened and run by decompression. It should be noted that this software needs to be run in a compatible way on Windows8 and Windows10 systems

The yellow area represents the button area that the user has drawn. Button properties are listed in the properties bar on the right of STONE TOOL software:

Then click the Text Variable just added, and the property interface will appear on the right of STONE TOOL software, mainly changing the following parameters:

Among them, "Variable memory addree" refers to the memory address where the displayed content is stored. One address can store two bytes. Our default display content is "OFF", which requires three bytes of memory space. This means that we store "OFF" in address 0020 and 0021.

The control we used above is "Button". This "Button" control does not return a value, which means that when the user presses the Button, the serial port of the display module does not send data to the MCU.

4. Insert the USB disk 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 5. test

After downloading the program to the display module, turn it on, connect the computer through the serial port via USB-TTL, press the light button of Light1, and return the serial port data: a55a 06 83 00 26 01 00 A8

0xA5 0x5A 0x05 0x82 0x00 0x20 0x55 0xaa Since we"ve set Light1"s text display storage address to 0x0020, writing data to this address using a serial port is equivalent to changing the content of Light1"s text display box.

We just need to add the designed UI images through menu bar options for buttons, text boxes, background images, and page logic through the host computer, then generate the configuration file, and finally download it into the display and it is ready to run.

To develop based on our STONE TFT LCD, you first need to use to an upper computer development software STONE designer, in this upper computer, all screen-related settings are carried out in this upper computer, so how to download it, click the link below to go to the official website：https://www.stoneitech.com/support/download

First add a button control to the temperature, select “button” control, and draw the corresponding area; then in the right feature settings, set the button effect, here select page 2, that is, when the button is pressed, the corresponding area to display the effect of page 2; then select the page switch function, here select the No. 4 page, that is, when this button is pressed, the page will immediately switch to page 4, that is, the temperature display interface.

Under the temperature display interface, a text display control is needed to display the real-time temperature data passed by the Arduino, so it is necessary to add a data variable control, as shown in the following figure.

First of all, you need to set the variable address of the control, this address is very important, the data of the micro-controller can only be displayed by sending data to this address, and then set the format of the display, here choose 2 integers and 1 decimal.

If you feel that the font size of the display is too small to see clearly, you can also adjust the font size, and finally the alignment, I generally choose the center alignment, of course, there are also left-aligned, right-aligned to choose.

The STONE TFT LCD sometimes needs to control the micro-controller to achieve a two-way interaction, which is also the case here, and needs to implement the start and stop acquisition function, using the START button as an example.

First set the key effect, here select page 2, when the key is pressed it will display the effect of page 2, here there is no need to switch pages, so select null, it should be noted that it is also necessary to set a variable address.

After setting, click compile, then insert the U disk, wait for the recognition to finish and click download to copy the project into the U disk, and plug in the display to upgrade. In this way, the whole project is finished.

Just a simple reminder, if you run into problems with your development, Stone has an official forum where you can ask technology-related questions https://forum.stoneitech.com/

Displays have over time, emerged as one of the best ways to drive user interactions on any device. They make it easy to collect inputs and present information (outputs) to users in a graphical, easy to understand format. This usefulness has led to improvements in their quality, with improved resolution and low power features, but almost little has changed when it comes to the complexity of creating beautiful user interfaces for them. This is why the team at STONE Tech created the STVC035WT-01 intelligent Smart display which we will explore for today’s tutorial.

The STONE STVC035WT-01 display is a 16-bit, 3.5″ display with a 320×480 (RGB) resolution, has a 49.0 x 73.4mm viewing area, and pixel spacing of 0.1905mm×0.0635mm (H×V). The display is a Class A industry Panel with an Industry level 4 wire resistance based touch screen, all layered on an integrated CPU, driver, and flash memory with several communication interfaces to enable it to connect to data sources like microcontrollers. For communication with a microcontroller, the display supports serial communication protocols likeUART/TTL, RS232, and RS485, ensuring it can communicate with any kind of microcontroller or industrial computers. The UART/TTL pin on the Display supports both 3.3v/5v logic level which adds another layer of ease to the use of the display as users need not worry about the need for logic level shifters when building using a microcontroller that operates on either of the voltage level mentioned.

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.

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.

The design is quite simple, we illustrate label elements to hold the date, the project title, and the values from the microcontroller. The values from the microcontroller include; the status of the connection between the microcontroller and the display, the heart rate, and the oxygen levels.

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.

1. With the software downloaded on your computer, launch it and go to File>New Project. This will launch the “New Project dialog box ” where you will be expected to fill in the details of your display, set the storage path, and the name of your project. Since we will use the STVC035WT-01 display which has a  resolution of 320*480 and a default flash space size of 128Mbyte (expandable to 1024MByte), I have entered its details as shown in the image below. If you are using any of the other StoneTech displays, you will need to enter the details of that display instead.

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.

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.

Next, we initialize the MAX30100 and send the status of the initialization to the display. If the initialization fails, 0x00 meaning 0 is sent to the display, but if successful, 0x01 meaning 1 is sent to it.

We start the void loop() function by calling for updated readings, after which we check if the reporting period has elapsed. If the reporting period has elapsed, it means we need to take new measurements, so we call the pox.getHeartRate and pox.getSp02 commands to get new heart rate and oxygen levels. These new readings are displayed on the serial monitor and also sent to the display.

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.

The quality, size ανδ variety of the STONE TECH displays makes them perfect for HMI Applications and one of my next projects will be a Home Automation Panel using one of the STONETECH displays.
