基于ZigBee，RFID，VB的智能养猪系统课程设计

LWIP + UCOSII示例代码,arm9开发平台(LWIP+ UCOSII sample code, arm9 development platform)

着是一个MATLAB中的图形合并的程序，也有不完善的地方，请指教！(with MATLAB is a graphic merger procedures have imperfections, please enlighten! Thank you)

1954北京坐标系，1980西安坐标系，WGS1984坐标系的地理坐标与大地坐标的相互转换，不包括坐标系统之间的转换。参考网上资料开发而来，经过实际数据验证，确实可用。欢迎借鉴。(1954 Beijing coordinate system, 1980 Xi' an coordinate system, WGS1984 coordinate system of geographical coordinates and geodetic coordinates of the conversion, not including the conversion between coordinate systems. Development of online reference materials come after the actual data validation, it will be usable. Welcome to learn.)

自定义一个简单的日期类DateType，它具有数据成员y、m、d，用来表示当前日期的年、月、日。而后设计该类欲实现（完成）的功能，进而设计出相应的类成员函数。 　　例如，下面给出的“雏形”可用来实现对天的增加，比较两个日期是否相等，以及对日期的输出等操作。请完成各类成员函数，并编制主函数，说明DateType类对象，对定义的各成员函数进行调用，以验证它们的正确性。 (Customize a simple date class DateType, it has a data member y, m, d, is used to indicate the current date, month, and day. To achieve the latter design class (complete) function, and then design the appropriate class member functions. For example, the following is the " prototype" is used to achieve the increase of day, compare two date are equal, and the output of dates and other operations. Please complete all kinds of member functions, and prepare the main function, indicating DateType class object for each member function definition be called to verify their correctness.)

说明：  这个文件可以参考它的IEC103通讯过程，没有复归和遥调功能(This file can refer to its IEC 103 communication process. It has no function of regression and remote adjustment.)

说明：  电机驱动和FOC算法分析，用st单片机和PSIN32F0实现。(The analysis of motor drive and FOC arithmetic is realized by ST MCU and PSIN32F0.)

C#多年积累的类库 1、图形操作 2、cookie，session以及cache 3、csv文件转换 4、FTP操作类 5、json处理 6、xml操作类 7、excel文件导出 8、时间日期操作类 9、上传下载 10、条形码 11、压缩解压缩 12、序列化 13、验证码 14、正则表达式等

本代码是一种随机改进粒子群优化代码，简单，易懂 有注释信息。C语言版本，无错误，直接可运行(This code is a random code to improve particle swarm optimization, simple, easy-to-understand annotated information. C language versions, error-free, can be run directly)

说明：  接到单片机上后，输出到示波器可以看到一定频率的方波，通过按键可以调节波形的频率，同时在显示屏上也可以产生对应的周期和频率，外加信号发生器，可以得出对应的周期频率(After being connected to the single chip computer, the square wave of a certain frequency can be seen when it is output to the oscilloscope. The frequency of the waveform can be adjusted by keystrokes. At the same time, the corresponding period and frequency can be generated on the display screen, and the corresponding periodic frequency can be obtained by adding a signal generator.)
