说明：  单片机主要进行对数据的实时采集、处理,再通过 串口将数据送入PC 机的缓冲区,然后由PC 机对 数据进行进一步处理,以便得到所需的图形、图像 及实验结果。采用VB 语言中的通信控件能够很 好地完成二者之间的通信功能
(Mainly single-chip real-time data collection, processing, and then through the serial data into PC-buffer, and then by the PC machine for further processing of data in order to obtain the necessary graphics, images and experimental results. VB language used in the communication control able to complete the communication between the two)
