说明：  单片机的串口通讯，可以实现单片机与单片机间，单片机与PC机间的串口通讯(Serial communication between single-chip computer and single-chip computer and between single-chip computer and PC can be realized by serial communication between single-chip computer and single-chip computer.)

说明：  自己画的开发板，用的STM32F103VGT6芯片，代码中使用了很多功能，基本的I2C，SPI，Flash读取，串口通信（WIFI，Enocean协议），等都有涉及，驱动代码不全是自己写的，所以有些地方没去在意备注，但是每个使用修改的地方都有我自己的备注，基本上就是自己的开发板，自己在研究学习验证的过程中一点一点整合起来的(I drew my own development board and used stm32f103vgt6 chip. Many functions were used in the code, such as basic I2C, SPI, flash reading, serial communication (WiFi, enocean protocol), and so on. The driver code was not written by myself, so some places didn't pay attention to the remarks, but every place I used and modified had my own remarks, which was basically my own development board In the process of research, learning and verification, I integrated them bit by bit)

编制MCS-51程序使步进电机按照规定的转速和方向进行旋转，并将已转动的步数显示在数码管上。 　　步进电机的转速分为两档，当按下S1开关时，加速旋转，速度从10转/分加速到60转/分。当松开开关时，减速旋转，速度恢复为10转/分。当按下S2开关时，按照逆时针旋转；当松开时，按照顺时针旋转。 　　本程序要求使用定时器中断来实现，不准使用程序延时的方式。(The MCS-51 program is programmed to rotate the stepper motor according to the specified speed and direction, and the number of steps that have been rotated is displayed on the digital tube. Stepper motor speed is divided into two gears. When the S1 switch is pressed, the speed is accelerated from 10 rpm to 60 rpm. When the switch is loosened, the speed will be reduced to 10 rpm. When pressing the S2 switch, rotate counterclockwise; when loosening, rotate clockwise. This procedure requires the use of timer interrupt to achieve, do not use the way of program delay.)
