PID控制规律及控制器实现

说明：  用FPGA进行等精度频率和相位差测量的程序，本程序是在EPEC6Q240C8下的程序(Carried out with the FPGA such as the frequency and phase measurement precision of the procedure, this procedure was the procedure under the EPEC6Q240C8)

SDRAM即同步动态随机存储器，同步是指memory工作需要同步时钟，内部命令的发送与数据的传输都以它为基准；动态是指存储阵列需要不断地刷新来保证数据不丢失；随机是指数据不是线性依次存储，而是自由指定地址进行数据读写

在QUARTUS II上实现（7,4）汉明码的译码VHDL语言设计((7,4)Hamming decoder)

说明：  ad9361 matlab驱动代码，运行此代码可在matlab中控制AD9361(AD9361 matlab driver code, running this code can control AD9361 in MATLAB)

说明：  libero soc工程，实现通过串口接收到单字节数据后并返回发送给上位机(Libero SOC project, which realizes receiving single byte data through serial port and sending it back to host computer)

说明：  基于labVIEW，控制电机等工作实例，程序基本完整(Based on labVIEW, control motor and other working cases, the program is basically complete)

DDR2控制器设计原码,可以在FPGA上测试通过,并对外部的ddr memory进行读写访问.(DDR2 controller design of the original code, can be tested through the FPGA, and external ddr memory read and write access.)

本模块适合所有红外接收端，使用时请注意修改地址码，要接收的就是识别用户码，代码里有标注，谢谢大家的支持！

Quartus II 7.2最完美的license破解器!(Quartus II 7.2 FULL and perfect License!)

vhdl测试程序，用于初雪者熟悉hdl的具体语法应用。比较简单了。(VHDL test procedure for the First Snow hdl who are familiar with the application of specific syntax. A relatively simple.)
