| 摘 要： | 以FTDI公司的FT232BL芯片为核心设计并实现了基于USB接口的计算机与单片机之间的虚拟串口通讯。单片机采用Philips公司P89系列单片机，完成数据的存储。计算机在Windows环境下利用MSComm通讯控件实现上位机与下位机之间的数据传输。在此提出了PC机对虚拟串口的自动识别方法，并提供了程序的源代码。实验结果表明，用虚拟串口实现计算机与单片机之间的USB通信，具有速度快，软件实现简单等优点。

| Abstract: | The communication between SCM and USB port based computer through virtual serial port is designed and implemented by taking FT232BL of FTDI Incorperated as a kernel.The data storage is completed by Philips P89 series MCU.The data tranmission between host computer and lower computers is achieved by means of MSComm communication control in the Windows environment.The method that PC automatically identifies the virtual serial port is presented.The source code of the program is provided.The experimental result shows that the USB communication between SCM and PC implemented by virtual serial port is speedy and easy to implement by software. |
