录制和播放wav文件，显示波形，并能够通过串口接收pcm语音数据，转换为wav文件播放-recording and playback wav documents, waveform, and through the serial data receiver pcm voice, Converting to wav Player

简单自绘波形图，附带串口访问程序，不过与波形无关-Simple self-drawn waveforms, with serial access program, but has nothing to do with the waveform

实现脑电波的串口数据采集，以及脑电波分波段实时波形显示。(The serial data collection of the EEG and the real-time waveform display of the brain wave are realized.)
