摘要
通用接口总线GPIB作为IEEE组织制定的仪器接口总线标准,用于将各种数字化的自动测量仪器相互连接起来,协同完成测量任务。然而GPIB和PC机连接时,需要通过昂贵的GPIB接口板卡,接入成本较高,这个问题在PC机连接一台带有GPIB接口的测量仪器时更加突出。本文提出一种PC机连接GPIB的解决方案,使用PC机的串口RS232,透过一个单片机连接GPIB,以较低的成本完成GPIB的接入。
The paper introduced the design of GPIB control unit based on RS232 interface. Through controlling interface chip TMS9914 of GPIB by SCM, it conveniently implemented the communication and control between computer and GPIB equipment in the serial communication super terminal within windows operating system.
