通过串口接收数据并实时画出曲线。将含有单片机，AD模数转换器等芯片的电路板通过USB数据线与电脑相连，可通过计算机实时显示出数据和绘制出图形-Through the serial port to receive data and real-time to draw curves.

AD转换实验,里面是c程序，可以直接IAR编译然后烧录到单片机里面，适用于无线传感网络实验。-AD conversion experiments, which is c program, IAR compiler can then burn to MCU inside for wireless sensor network experiments.
