What is STONE HMI?- human interface with TOOLBOX sofawsre


An HMI, also known as a human interface, is a display that allows a user to control and monitor his or her machine.A common example of an HMI is an ATM machine, coffee machine, or beauty machine on which the user can interact with the machine using screens and buttons.

Today, through this guide, we will introduce:

  • Introduction to HMI
  • HMI and STONE
  • Why use STONE HMI
  • STONE HMI display
  • STONE display starter
  • HMI project concept

Introduction to HMI - human interface

  • A human interface is a component of certain devices that allows the user to interact with the machine.
  • The interface consists of hardware and software that provide information to users by allowing them to input signals that are converted into machines.
  • Information including temperature, pressure, speed, time, battery and so on!
  • The interface can also have a variety of forms and sizes, including: 3.5 ', 4.3 ', 5 ', 5.6 ', 5.7 ', 7 ', 8 ', 9.7 ', 10.1 ', 10.4 ', 12.1 ', 15.1 '.
  • With HMI, you can closely monitor the machine and control and maintain it.This, in turn, can improve efficiency, diagnosis, and monitoring.
  • One of the biggest benefits of HMI is the user friendliness of the graphical display.You can add colors and images to easily and quickly identify problems.
  • You can use an HMI almost anywhere you need human intervention with a machine or automated device.For example, you can use them with medical beauty equipment, 3D printers, engineering projects, automobiles, etc.


Reference: STONE

  • STONE provides intelligent HMI solutions.Any smart TFT LCD module with an MCU (with a cortex-m4 32-bit CPU) can be controlled with simple hexadecimal instructions via the UART port.
  • The module consists of CPU, TFT drive, flash memory, UART port, power supply and so on.STONE also provides basic controls and powerful design software (STONE TOOL Box).
  • You can use the STONE TOOLBox software to set up various functions on the graphical user interface, such as text, graphics, curves, image switching, keyboard, progress bar, slider, dial, clock and touch buttons, data storage, USB download, video and audio.
  • Engineers can easily develop the tft-lcd color user interface and touch control features, which can reduce a lot of development time and cost.
  • STONE is mainly used in the field of industrial electronics.It is the best solution to replace the traditional LCD and LED digital tube.
  • You can easily connect the STONE HMI display via TTL serially through its peripheral MCU to provide event notifications that the peripheral MCU can execute.
  • With the STONE HMI display TTL serial interface, you can easily connect them to microcontrollers like STM, RAM MCU, Arduino and Raspberry Pi, or any system that can communicate via serial ports.

 Why use STONE HMI

Easy to use



  • First, STONE is easy to use.With the STONE STONE TOOLBox software, you can easily create intuitive touch user interfaces, even if you're a beginner.
  • For example, by adding a static image as a background and defining functionality by component, you can easily and quickly create a simple GUI in just a few minutes.
  • With drag-and-drop components and simple instructions, you don't have to spend a lot of time on HMI project development.


  • Engineers can easily develop the tft-lcd color user interface and touch control features, which can reduce a lot of development time and cost
  • The products are divided into three series, the advanced series for medical beauty, the industrial series for industrial electronics, and the lowest price for civil use.According to their own needs, choose the right type of screen.







Various TFT LCD touch screen sizes from 3.5 inches, 4.3 inches, 5 inches, 5.6 inches, 5.7 inches, 7 inches, 8 inches, 10.1 inches, 10.4 inches, 12.1 inches, 15.1 inches, there are many models and options for the same size.

STONE HMI Display Project idea

Here are some STONE HMI Display project ideas to get you started!

Use the STONE LCD module to create a refrigerator control

Reference: create refrigerator controls

Our fridge is not possible with any of the man-machine interface, but if there is a refrigerator with human-machine interface, let users can through the touch screen operation, control of refrigerator on the lower cooling efficiency, display the current the temperature inside the refrigerator, display the current indoor and outdoor temperature, and some feedback on the usage of refrigerator (days running, filter life, etc.), so, it is very convenient and practical for users.

What do you need?

Running state includes:

  1. Operation days
  2. Filter element life
  3. Outdoor temperature
  4. Indoor temperature

To obtain these data, in addition to the first, the other three need the the corresponding sensor to collect these data.
Filter element lifetime acquisition sensor and temperature sensor are required respectively.
When the single-chip microcomputer collected these data, through the serial port to the designated display control address transmission data, the value of the display control on the corresponding change.

Running days can be implemented in two ways:

  1. Use the RTC of STONE STVC050WT-01 serial port display screento display data directly on the screen
  2. Use the single chip microcomputer's RTC to transfer data to the serial port screen for display

The STONE STVC050WT-01 serial port display comes with the RTC, which can be found in the STONE in development guide.

Arduino uno + STONE LCD + Displays data read by MFRC522

reference:Displays data read by MFRC522

Due to my personal interest, I learned about the development of Arduino UNO and STONE LCD module project for two weeks, and found Arduino very simple, convenient and practical.So I wanted to do a simple demonstration with Arduino.I had an MFRC522 module at home, which I used in college, but I used STM32 to communicate with MFRC522, so I had to write my own driver for MFRC522 module, which was very complicated.

What Do You Need

STONE STVC050WT-01 display

Arduino UNO development board

MFRC522 module

Liquid crystal display

The MI card

LCD Arduino + STONE HMI +According to the heart rate


Heart rate sensor module MAX30100 can collect users' blood oxygen and heart rate data, easy to use.

I found the MAX30100 library in the Arduino library file.That is, if you use communication between the LCD Arduino and the MAX30100, you can call the Arduino library file directly without having to rewrite the driver file.This is a good thing, so I bought the MAX30100 module.

I decided to use Arduino to verify the MAX30100's heart rate and oxygen collection capabilities.STONE TFT LCD screen for monitoring blood pressure.

What Do You Need

  • Arduino Mini Pro development board
  • MAX30100 heart rate and oxygen sensor module
  • STONE STVI070WT-01LCD serial display module
  • MAX3232 module
