摘要
在工业测控中,串行通信设备、ADC/DAC设备随处可见,这些设备常常需要跟主机相连,组成一个PC机和工业电子设备构成的监控系统,而普通PC机所能提供IO接口的数量和种类又非常有限。因此,经常需要对PC机IO口进行扩展。以某工程项目中的一块基于ISA总线的自制多用途卡为背景,从工程的角度阐述了WDM模式下驱动程序及其动态链接库的开发。
In the industrial measurement and control,serial communications equipment and ADC/DAC equipment can be seen everywhere, these devices often connected with the mainframe, and constitute the monitoring system that include PC and Industrial electronic equipment. But ordinary PC can provide the number and types of IO very limited. Therefore,often need expansion for PC IO. In this paper, taking a project based on the ISA bus and self-made ＆multi-purpose card in the background, from an engineering point of view expounded development of the card driver and dynamic link library.
