摘　　要：本文阐述了在嵌入式Linux系统下设计GPIB设备的方法。利用已广泛应用的IEEE488（GPIB）总线协议，设计了基于ARM微处理器的GPIB板，并通过编写相应的驱动程序来实现一台GPIB仪器（设备）的功能，可以将USB接口的数字存储示波器转换成GPIB接口的示波器。相对于以往类似的设计有更好的扩展性和可移植性。This article expounds a method of designing GPIB device in embedded Linux system environment. IEEE 488（GPIB） bus protocol, which has been widely applied, is adopted to design the GPIB bOard based on ARM microprocessor. And, a GPIB device＇s function is realized by writing a relevant driver program. By so doing, USB interface of digital storage oscilloscope can be convetted to the GPIB interface. Compared with previous analogous designs, the design has better expansibility and transportability.
