对51单片机的串口功能进行测试，可以提供初学者进行相应调试(For 51 singlechip serial function testing, can provide beginners corresponding debugging )

交通等单片机程序很好的，可以下载看看，应该没有错误的 (Transportation and other microcontroller program good, you can download to see, it should not be wrong)

说明：  输出PWM波，可移植性强。适用于stm32F103系列的单片机。例子也比较经典。(Output PWM wave, strong portability)

stm32f103zet6 使用freertos，在IAR平台下开发，静态任务(stm32f103zet6 freertos)

说明：  使用超声波模块测距，测距范围 10cm--1..2m(Using ultrasonic module to measure distance, ranging range is 10cm-1.2m.)

说明：  纯数字电路实现4位密码锁，15秒倒计时功能，简易原器件，课程设计，proteus仿真(Pure digital circuit to achieve 4-bit password lock, 15 seconds countdown function, simple components, Proteus simulation, curriculum design)

利用51单片机实现无线通信程序，测试可用(Using 51 single chip wireless communications procedures, testing available)

说明：  emWIN,解决64位机不能使用软件工具的尴尬，可以说是前期版本的升级版5.22版本(EmWIN, to solve the embarrassment of 64-bit computers not using software tools, can be said to be the upgraded version of 5.22 version of the previous version.)

根据对应的按键值，对应输出相应的电容值，并做掉电检测(According to the corresponding key value, corresponding to the output of the corresponding capacitance values ​ ​ and do brownout detection)
