STONE HMI serial port screen, which is very suitable for the display screen of the ventilator.  In addition, I need a single-chip microcomputer to process the commands issued by the STONE HMI screen and upload some waveform data in real-time.  Here, I chose a more general and easier to use MCU, Arduino UNO single-chip microcomputer, which is widely used and supports many libraries.
The following will describe the detailed process of the development of the Arduino Uno STONE HMI Medical Ventilators project

In this project, you can control the Arduino UNO development board by using the STONE HMI serial port screen and carry out data command interaction through serial port communication. The Arduino Uno development board can upload a series of waveform data and display it on the serial port screen. This project is very helpful for making the ventilator display screen.

ARDUINO UNO STONE HMI Medical Ventilator Project Overview

The ventilator project I do here will have a startup animation effect after power on, then enter a startup initial solution interface, and display the word “open”. Click it to have a voice effect, prompt to open the ventilator, and jump to the page selection interface, where there will be an animation effect, which is an animation to show the human breath, and there are two options The first is the oscillogram monitoring chart of respiration. The second is the oxygen and respiratory rate monitoring chart. How to display so many oscillograms at the same time is a problem. After clicking enter, STONE HMI will issue a specific command to control MCU to start to upload the waveform data.

The functions are as follows:

1. realize button setting;
2. Realize voice function;
3. realize page switching;
4. realize real-time waveform transmission.
