HLS协议实现

详细记录了实现w5500实现UDP功能测试的原始方法，代码具有代表性的说明了w5500的使用方法。 本方案给予STM32F429discovery。使用spi1接口作为w5500控制口。 驱动电压可以为3V也可以为5V。 更具测试版选择。 

一个用于ARM的基4/基5定点FFT算法，原作者是JDB，后来我扩展过16和256点的计算并用在项目中了，感觉速度还不错。现在重写了基于Linux GCC4的测试程序，可供使用者评估参考。建议安装FFTW3用来精确评估测试结果，相关范例已经在代码中了。-Radix 4/5 FFT routines supporting 16/64/256 and 20/80 calculations. The source originally contributed by JDB, I had extended 16 and 256 candidates and used it in our project it has been verified as fast and stable. Now we add some test vectors running on Linux with GCC 4 for testers who want to use or just evaluate it. Installing FFTW3 is recommended for evaluating the code exactly.

应用背景本代码是STC系列单片机移植uCOSII操作系统的例程，51单片机大家都熟悉，因此在学习uCOSII操作系统的时候就不用过多考虑硬件问题，更方便uCOSII的学习与理解，为移植更强的单片机做铺垫。关键技术移植uCOSII的关键是对51单片机有个底层的了解，以及核心代码的修改，了解一点汇编的知识，对于操作系统算是一个入门，不会让你觉得操作系统很难。

自己的参赛程序（附带使用说明），利用Freescale JM Board实现类似于赛车的躲避游戏，且控制方式可以通过触摸板或重力加速度控制。其中用到三轴加速传感器7260和接近式电容传感器MPR084。对这两个器件感兴趣的可以参考-Their entry procedure, and use Freescale JM Board to achieve similar to the car to avoid the game, and the control mode can be controlled through the touch pad or the acceleration due to gravity. Which uses three-axis acceleration sensors 7260 and the proximity capacitance sensor MPR084. Interested in these two devices can refer to the
