目前国内有关数字信号处理的教材在讲解快速傅里叶变换（FFT）时，都是以复数FFT为重点，实数FFT算法都是一笔带过，书中给出的具体实现程序多为BASIC或FORTRAN程序并且多数不能真正运行。鉴于目前在许多嵌入式系统中要用到FFT运算，如以DSP为核心的交流采样系统、频谱分析、相关分析等。本人结合自己的实际开发经验，研究了实数的FFT算法并给出具体的C语言函数，读者可以直接应用于自己的系统中。--I implemented FFT algorithm in real number and provides a C function. Users could use it directly in their systems.

c语言编写的配置文件读取程序，支持特定格式 读写，就这样了 还写啥 有啥好写的。字数够了吗？！

Setup_SmartRF_Studio_6_0_4是一个CC1000系列中的开发工具，对开发无线产品非常有用，可以用该工具进行先期的调试。绝对是个好东东。-Setup_SmartRF_Studio_6_0_4 CC1000 is a series of development tools for the development of wireless products very useful, the tool can be used for the initial task of debugging. Definitely is a good Dongdong.
