说明：  nrf24l01通信的个别程序，希望有用(Nrf24l01 communication individual procedures, hope useful)

S变换时频域滤波是一种二维的时间域—频率域的分析方法，此程序通过对信号进行时频域转换，通过分析干扰信号的时间与频率的分布范围，设计相应的滤波器进行滤波可以有效的去除干扰，又因为S变换的是无损的可逆的因此对信号没有损伤。(S transform time domain filtering is a two-dimensional time domain - frequency domain analysis method. By analyzing the time and frequency domain of the signal, by analyzing the distribution range of the time and frequency of the interference signal, the corresponding filter can be designed to remove the interference effectively, and because the S transform is nondestructive and reversible. There is no damage to the signal.)

c源代码,模拟示波器,开发环境VC6,使用方法见说明(C source code, analog oscilloscope, development environment VC6, use method see instructions)

说明：  这是高光谱图像基于局部的空间预处理算法demo.(this is a demo of hyperspectral region-based spatial preprocessing algorithm.)

说明：  电压电流双闭环DCDC升压斩波电路，也就是Boost电路。仿真各模块清晰明了，通俗易懂，适合自己搭模型时参考使用。此文件已经改为MATLAB 2010a版本，方便大家使用。(Voltage and current double closed-loop DCDC boost chopper circuit, that is, boost circuit. Each simulation module is clear and easy to understand, which is suitable for reference when setting up the model. This file has been changed to Matlab 2010a version for your convenience.)

说明：  采样返回上位机，上位机处理后串口发送至单片机，实现pid调节，需配合simulink使用(Sampling is returned to the upper computer. After processing, the upper computer sends the serial port to the single chip computer to realize PID regulation. It needs to be used with simulink.)
