Embodiment Construction

[0035] In order to make the purpose, content and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0036] The invention belongs to a technical method for enhancing the reliability of PS2 device connection under the VxWorks system. In the application scene of the VxWorks operating system, in view of the fact that the process of querying, loading and driving the PS2 device is too simple, according to the principle of PS2 device loading, a Design of a robust PS2 device loading process. The invention perfects the driver for loading and connecting PS2 equipment of the VxWorks operating system, and ensures the reliability and success rate of loading the PS2 equipment during the startup process of the VxWorks operating system.

[0037] To achieve the above object, the present invention takes the following technical measures...

Abstract

The invention relates to a method for solving loading failure of PS2 equipment in VxWorks graphic development, and belongs to the field of embedded software development. According to the invention, the method includes adding, in WindML configuration, a ps2master component; modifying a drive file of the PS2 equipment under a componens path, and adding a code for perfecting a drive; and compiling WindML, and applying the change to an operating system. The invention has the capability of resisting the loading failure caused by operating the PS2 equipment (moving a PS2 mouse or operating keyboardkeys) in the starting process of the VxWorks operating system, a large number of experimental verifications show that the method is stable and reliable, and the loading reliability and success rate ofthe PS2 equipment in the starting process of the VxWorks operating system can be guaranteed.

Description

technical field [0001] The invention belongs to the field of embedded software development, and in particular relates to a method for solving the failure of PS2 device loading in VxWorks graphics development. Background technique [0002] The VxWorks operating system is widely used in my country's shipbuilding, communications, military, aerospace and other high-tech and real-time demanding fields. In these fields, the working environment and electromagnetic environment are relatively harsh, and the PS2 protocol has the characteristics of good anti-interference performance and long transmission distance. Therefore, in graphics applications developed based on VxWorks wimdML, most of the manual input devices adopt the PS2 interface form . The WindML layer of the VxWorks operating system only provides simple driver support for PS2 devices, and does not deal with abnormal situations accordingly. The robustness is not strong. It is easy to cause the PS2 mouse to fail to load, an...
