Tutorial: Use the STM32 development board and STONE LCD screen to develop beauty devices with touch screens

Because I have a lot of contacts with ST, MCU like this type can generally plug in the screen through IIC or SPI or serial port, such as 0.96-inch display screen, 1602 LCD screen, and various TFT LCD screens, and I decided to use the STONE LCD screen to do this project. Speaking of the STM32 board.

Project Requirements

Here we want to do a project about the use of medical devices and instruments. This project is mainly through our STVC101WT-01 serial port screen, through the touch mode. After pressing the key, the serial port screen sends the serial port command to STM32l053r8 through the serial port command. When our STM MCU receives the specific command, it starts to analyze the command, This resolution protocol is specific, which will be discussed later. After that, MCU will analyze and recognize specific fan instructions and led instructions, so as to realize the control of fan and led.

There Are Four Functions

• Serial port screen realizes touch key function
• Send touch command
• MCU analyzing instruction
• Control the FAN and LED

After The Function Is Determined, We Need To Select The Model Of Each Module:

• Type of touch screen
• What kind of MCU module do we use
• What kind of peripheral module to use

I plan to use STVC101WT-01 serial port screen for touch screen, after all, it is very convenient to use, and the market also has a certain proportion, the most important thing is that it is easy to use; the problem of the screen is solved, and then an MCU should be selected. Why do I use STM32l053r8 for MCU? Because the global market share of St MCU is more than 11% in 2015;

We use a 5V 4W DC power supply for the fan so that it can be controlled directly through the IO port; an ordinary LED is used.
