无起摆，单纯180度倒立稳定，2个PID闭环控制采用编码器位置环和电机速度环(No pendulum, simple 180 degree inverted stability)

光伏并网逆变器的仿真以及参数的设定，采用传统配置(inverter Simulation of photovoltaic grid-connected inverters and parameter settings using traditional configurations)

C++与MFC结合以实现的餐厅桌号预订系统（基本功能有：1、 餐厅提供小，中，大三种餐位；2. 每种餐位若干，每个餐位都有相应的编号；）3. 每种餐位使用收取的费用不同； 4. 每位客人根据就餐人数选择不同类型的餐位，系统则根据等待人数给用户生成一个等待号码，显示客人当前排号以及在他之前有多少位客人在等待。 5. 不同类型餐位都有自己的一个等待列，为客人生成的号码互不影响； 6. 支持查询指定号码所在的餐位； 7. 实现日志功能（记录每天所有餐位的使用状况，收入）； 8．客人可以动态查看当前餐位使用情况（每种餐位当前排到多少号等） (C++ with MFC combined to realize the restaurant the table No. booking system (basic functions: 1, the restaurant offers a small, three seats 2 bits of each meal, each seating has a corresponding number ) each seating fees charged each guest to choose different types of seating dining number, wait for the number to the user-generated a waiting number the show guests Arranging and before him the number of The guests in the waiting. 5 different types of seats has its own a waiting column the guests generated numbers independently of each other 6. Support to query specified number where seats 7 log function (recording daily use for all seats, income) 8. Guests can dynamically view the current usage of seating (each seating routed to what number, etc.))

定时器,界面写的差不多了,还不够完善,可以按每天,每周,每月,每年来增加定时器.(Timer, interface written about, but not perfect, you can press daily, weekly, monthly, annual to increase the timer.)

说明：  用stm32f103控制无源蜂鸣器播放音乐(Using STM32F103 to control passive buzzer to play music)

51单片机操作系统-圈圈任务完整，简述了一个基于51单片机的简单操作系统的设计。

该文件是一个比较全面的c语言函数文档，包含了全部的函数(The file is a more comprehensive documentation of the c-language function, contains all the functions)

基于瑞萨（原NEC）8位单片机79F8513A开发的新风系列控制板。 主要功能，ADC采集，串口通讯，输入扩展74HC4051D，IO口模拟I2C通讯，新风机组风机控制等功能。(The new wind series control board is developed based on the 8 bit single chip 79F8513A of NEC. The main function, ADC collection, serial port communication, input extended 74HC4051D, IO port analog I2C communication, fan control of new wind unit, etc.)

UKG(Unique Key Generate Server)是一个生成唯一ID的服务器, 是根据Twitter的snowflake算法写成的, 主要用于高效的生成唯一的ID, 核心就是毫秒级时间(41位)+机器ID(10位)+毫秒内序列(12位).         其原理结构如下: 00000000000 0000000000 0000000000 0000000000 0 | 00000 |00000 | 0000000000 00 ---------------------------------------------- ----- ----- ------------- 时间戳 | workerId | datacenterId | 毫秒内序列         UKG每秒能够

说明：  turbo码的c语言程序，使用c语言来完成整个turbo码的编解码过程，并且程序后附带比较详细的解释(turbo code c language program, use c language to complete the entire turbo code codec process and procedures attached to explain it in more detail)
