一种WindML双屏显示驱动程序设计方法

针对电子装备软硬件平台对双屏显示输出的基本要求,探索了在VxWorks系统下开发WindML双屏显示驱动程序的方法。分析了WindML图形系统驱动程序体系结构,通过在图形驱动和WindML图形接口之间增加一个双屏显示控制层的方法,由双屏显示控制层接收WindML图形接口指令,再传给图形显示驱动程序,实现双屏显示输出。该方法设计的双屏显示驱动,能够使两个分开的屏幕逻辑上合为一个大的屏幕,很好的解决了WindML双屏显示输出的问题。

The Design of Dual-Display Graphic Driver for WindML

According to the requirement to Dual-Display in electronic equipment soft-hardware console,explores the method of designing the Dual-Display graphic driver based on WindML3.0. This paper analyses the architecture of the graphic driver in WindML3.0,designs the method of adding the Dual-Display driver between WindML API and graphic driver,the Dual-Display driver receives the instructions,and controls the graphic driver,so the Dual-Display driver is realized. By the method,two dividual screens become a whole big screen,the question of Dual-Display is well solved.
