基于LINUX平台的PCI数据采集卡驱动软件设计

Linux-Based Driver Design of PCI Data Acquisition Board

以一种PCI数据采集卡为例,介绍在Linux操作系统中PCI设备的内核模块驱动程序设计.该驱动程序已成功地装入EPICS系统,建立了EPICS数据库与PCI数据采集卡的数据通道,在EPICS环境下通过了测试。

Taking a PCI data acquisition board as an example, this paper describes the design approach of the PCI driver kernel module on Linux platform. This driver has been installed in EPICS system (Experimental Physics and Industrial Control System). Data channels have been built between EPICS database and PCI data acquisition board and tests have been done in EPICS environment. The PCI board, a new alternative I/O interface device is provided for the EPICS users.
