本文以ISA 采集卡的驱动开发为例讨论基于Windriver 的设备驱动开发。对基于Windriver 的驱动开发的原理、过程以及开发中的关键环节做了深入探讨。并在某高炮的轴角转换采集卡的驱动开发中得到了成功的应用。 关键词:Windriver 驱动开发 ISA 数据采集 Abstract: This paper introduces the development of the device driver based on Windriver, taking ISA data collecting card for example. It puts emphasis on the theory and the process of driver development. And it also introduces the key taches of the process. The success in a collecting card of one kind of archibold proved that it is very efficient. Keywords: Windriver Driver Development ISA Data Collection
