Application of massage chair STONE 10.1, STONE TFT LCD ESP32 massage chair Hi Friends! Hope you're well today. I welcome you on board. In this post today, I'll walk you through the application of a massage chair STONE 10.1 inch STVC101WT-01 TFT LCD with ESP32.Let's get started.

Brief Introduction

Massage chair with modern mechanical technology to reproduce the traditional Chinese medicine meridian massage is an important daily health care equipment. The function of the massage chair is to integrate meridian massage of traditional Chinese medicine with modern high-tech means to help users enjoy a comfortable massage, reduce fatigue, and achieve the effect of health care and physical fitness. With the development of single-chip microcomputer intelligent control, a massage chair with a large screen control application is also added.What we need to do here is such an application, select different modes through STONE TFT LCD screen, realize the control of MCU through serial port communication, and then realize the speed and rotation time control of stepping motor by controlling the level of specific IO, to realize the massage function of head and back. The system uses a STONE TFT LCD serial port screen, which can be used to do touch display function. It is very convenient to develop. Only through the serial port can the MCU be controlled.It is used in the massage chair, which can easily realize the setting of a massage function and the adjustment of massage strength, to achieve the effect of self-cultivation and reduce fatigue.Application of massage chair STONE 10.1, STONE TFT LCD ESP32 massage chair

Project Overview

Here we do is a home massage chair application, will STONE TFT After the LCD serial screen is powered on, a start interface will appear. After a short stay, it will jump to a specific interface. This interface is used to set our current time. When setting, a keyboard will pop up.After setting, click OK to enter the massage mode selection interface. Here, I have set three modes: head massage, back massage, and comprehensive mode. In the mode, the massage intensity can be set, the high, middle and low gears can be set, and the corresponding LED light will be used for intensity indication; the massage times can also be set, after reaching the set number, it will automatically stop; in the comprehensive mode, the head and back will be massaged at the same time, and it can be turned off when it is not needed. These actions are through the STONE TFT LCD serial port screen to achieve command transmission. 

The communication functions are as follows:

 
  • ① The serial port screen of STONE TFT LCD realizes the function of button switching interface;
  • ② The serial port screen of STONE TFT LCD realizes the function of an automatic jump when starting up;
  • ③ The serial port screen of STONE TFT LCD realizes time setting;
  • ④ The serial port screen of STONE TFT LCD realizes data variable distribution;
