TFT液晶LCD的控制器HX8345的驱动程序-TFT LCD LCD controller driver HX8345

1)生成2KHz和8KHz的混合信号，使该信号通过上述滤波器，观察滤波前后的波形变化和频谱分布情况。 2) 在改信号中加入高斯白噪声，观察滤波前后的波形变化和频谱分布情况3) 将上述滤波器改为中心频率为100KHz的带通滤波器，信号源为带外的90KHz和带内的100KHz的混合正弦信号，。 4) 用M文件实现上述低通滤波器。 -1) 2KHz and 8KHz to generate the mixed-signal, so that the signal through the above-mentioned filter, filter before and after observation of the waveform and spectrum distribution of the changes. 2) add to the signal in white Gaussian noise was observed before and after filtering and spectral waveform changes in the distribution of 3) will be replaced by the above-mentioned filter center frequency of 100KHz band pass filter, the signal source for the band and the band of 90KHz 100KHz Sine of the mixed signals. 4) achieve the above-mentioned documents with M low-pass filter.

即时通信的服务端软件，用于连接，聊天等操作-instant messaging server software, used to connect, chat, etc

使用softAP实现多方聊天通讯的例子源码，首先把多部手机连接到一个局域网中，在一个手机上安装服务端，然后服务端会自动显示一个可访问的IP地址并等待客户端连接，在其他手机上安装客户端，输入服务端显示的IP地址点击连接就可以与服务端进行连接，不需要改动源码里面的任何东西，亲测有效。
