读取SHT20的数据发送到主控STM32F103vet6(Read data from SHT20 and send it to master STM32F103vet6)

实现串口通信 可以收发数据 可以是数字也可以是ASCII(Serial communication)

说明：  orthogonal frequency demod

matlab程序，包括QPSK,16QAM,64QAM等多种调制方式的调制解调(modulation and demodulation of QPSK,16QAM and 64QAM etc.)

说明：  matlab里使用simulink仿真出qpsk系统通过AWGN信道的调制解调过程，并分析其误码率(Using simulink in matlab to simulate the modulation and demodulation process of qpsk system through AWGN channel and analyze its bit error rate)

说明：  利用商用WIFI和matlab对走、坐和蹲的三种数CSI 数据包进行预处理和特征提取(Commercial WIFI and matlab were used to preprocess and extract features of walking, sitting and squatting CSI packets)

欢迎大家下载学习，真的是一个好程序，小波包分析提取振动信号中的特征频率。( Welcome to download the study, Really is a good program, Wavelet packet analysis to extract vibration signal characteristic frequency.)

a reference book about stability of time delay systems

说明：  C语言函数库大全电子书,内容丰富,全面,极具参考价值,,(C language function library e-book, rich in content, comprehensive, very valuable,)

说明：  一种PC与单片机多机RS232串口通信设计应用(A PC with a single-chip multi-machine RS232 serial communication design application)
