基于IVI规范的429驱动程序设计

Design of 429 Driver Based on IVI Specification

结合ARINC429 VXI模块,参照其他类的IVI规范,探讨了429驱动函数的规划方案,由于IVI有关429通讯类仪器尚未制定类驱动规范,本文实际上也就是尝试制定了一种简单通用的429仪器类驱动规范,按照这一类结构,已经成功实现三个公司429仪器的互换,同时,对比较关键的IVI驱动程序的编制方法和配置文件作出了详细的定义说明,该方法和规则对于其他的虚拟仪器驱动程序的开发具有参考与推广价值。

This paper introduces a design of the 429 driver which is used for the ARINC429 VXI module. For the IVI foundation has not released 429 communication class, actually, this paper tries to design a kind of simple 429 communication class specifications, refer to other IVI class specifications. Based on this class specifications, the interchange of three 429 instruments made by different companies have completed. The software architecture, structure, and the procedure of IVI driver is also indicated in detail. This method and IVI specifications are valuable to develop the driver of other virtual instruments.
