DSP2812，BLDC,无刷直流电机，无位置传感器控制(DSP2812, BLDC, brushless DC motor, sensorless control)

说明：  MVVM架构，实现登录+增删改查图书管理。适合新手学习(MVVM login + add, delete, modify and check book management)

医院运维流程管理，简单的管理功能，可自行修改，感谢分享(Hospital operation and maintenance process management, thanks for sharing.)

说明：  C sharp远程连接SQLSERVER数据库，创建公共访问类，可适用于所有窗体。(Remote connection to SQLSERVER database)

说明：  用C#对sql数据库实现增删改查的入门级示例，带数据库脚本文件和实训报告。(An introductory example of adding, deleting and modifying SQL database with C# and database script file and training report.)

说明：  C#高性能大容量SOCKET并发完成端口例子，里面包括有导出直接运行的例子，还有delphi版和C#.NET版的源码，对开发端口程序很有帮助。(C # high-performance large-capacity SOCKET concurrent completion port example, which includes examples of direct export operation, as well as delphi version and C # .NET version of the source code, which is very helpful for developing port programs.)

用C#开发屏幕截图的源代码,只有源码,不含工程文件(C# development screenshot of the source code, only the source code, project file does not contain)

该C#程序的功能室通过C#编程，调用KML接口类，通过将KML语句写入txt文件并保存为.KML文件的方法，来创造出需要的复杂的KML图形文件，尤其是涉及到计算的形体，例如一个多点球体。(Method function room procedures through the C# C# programming, call KML interface class, the statement by writing KML file and save it as .KML txt file to create complex graphics files KML needed, especially with regard to the calculation of body , for example, more than one penalty body.)

自己的第一个程序，供初学者看看，一个关于产生随机验证码的程序(Own the first procedure for beginners to see, a random code generated on the procedures)

STM32F407 SPI1初始化 AD5624寄存器24位直接写入数据 命令位  （直接操作010命令 写入寄存器并更新所有） 地址位 （配置所有DACs） AD5624 写入寄存器 D11-D0 最大值为4095， 此芯片是外部参考电压（例3.3v）,输出电压为0.5v :(4095*0.5/3.3)写入到D11-D0即可。 可能是spi不稳定造成了配置一遍无法输出电压，所以进行了三遍配置才成功。
