STM32 development board tutorial：use STVC101WT-01 to control STM32
Brief
This article mainly aims at making a simple design of beauty instrument, teaching everyone how to use STONE LCD screen to develop a beauty instrument with touch screen, as shown in Figure 1 below:

Figure 1
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 STONE LCD screen to do this project. Speaking of 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：
①.Serial port screen realizes touch key function;
②.Send touch command;
③.MCU analyzing instruction;
④.Control the FAN and LED.
After the function is determined, we need to select the model of each module:
①. Type of touch screen;
②.What kind of MCU module do we use;
③.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 screen is solved, and then a 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 5V 4W DC power supply for fan, so that it can be controlled directly through IO port; ordinary LED is used.
Introduction and principle of each hardware
Fan
Generally speaking, fans have fan blades, which are electric driven devices to generate current. The fans configured in the fans are powered and then turned into natural wind to achieve cool effect.
Structure
Rotor: it is composed of magnet, fan blade and shaft; stator: it is composed of silicon steel sheet, coil and bearing; control circuit: it is composed of IC induction magnet N.S. pole to control its coil conduction through circuit and generate internal excitation to make rotor rotate. Type: axial fan, DC fan. Size: 40mm * 40mm * 15mm.

Figure 2
Working principle
The main components of the electric fan are: DC motor. Its working principle is: the electrified coil rotates under the force in the magnetic field. The transformation form of energy is: electrical energy is mainly converted into mechanical energy, and because the coil has resistance, it is inevitable that part of electrical energy will be converted into thermal energy.

LED
LED. It is made of compounds containing gallium (GA), arsenic (as), phosphorus (P), nitrogen (N), it can radiate visible light when electrons are combined with holes, so it can be used to make light-emitting diodes. In circuits and instruments as indicator lights, or composition of text or digital display.

in addition to the data manual, there are user manuals, common development TOOLBox, drivers, some simple routine demos, video tutorials, and some for testing projects.
STM32L0538
The ultra-low power STM32l053x6 / 8 microcontroller combines the connection capability of universal serial bus (USB 2.0-less crystal) with the high-performance arm cortex — M0 + 32-bit RISC core running at 32 MHz.
STM32l053x6 / 8 device has many analog functions, one 12 bit ADC, one DAC, two ultra-low power comparators, multiple timers, one low power timer (LPTIM), three general 16 bit timers, one basic timer, one RTC and one systick can be used as time base. They also have two watchdog, a watchdog with independent clock and window functions, and a window watchdog based on bus clock.
In addition, STM32l053x6 / 8 device also embeds standard and advanced communication interfaces: up to two I2C, two SPI, one I2S, two USART, one low-power UART (LPUART) and one crystal free USB. The device provides up to 24 capacitive sensing channels, which can simply add touch sensing function to any application.
