摘要
提出了一种基于PC104模块的嵌入式计算机串并口通信系统,该系统可与外部设备进行多串口通信,并可通过扩展IO控制和读取外部开关量。
This paper introduces a serial and parallel communication system of embedded computer based on PC104 modular. This system can communicate with external device by multiple serial ports,and also can control and read external switching value by extended I0.
