Problems solved by technology
At present, using CPCI+FPGA devices as the serial system architecture has gradually become the mainstream solution for realizing high-speed serial communication, but because the writing of Windows drivers requires developers to have an in-depth understanding of the Windows kernel and a large number of kernel debugging skills, a little carelessness It will cause the system to crash, and the source code of the Windows XP system kernel is not open, and it is difficult to get started with the driver development involving the operation of the Windows XP system kernel. Now most of them are developed and implemented by the CPCI driver under VXWorks and other systems, and the driver does not have a general purpose. Different RS422 communication boards require different drivers. At present, there is no CPCI driver developed for the newly developed RS422 communication boards under the Windows XP system. The driver development for the newly developed RS422 communication boards becomes Problems to be Solved Urgently in Production Activities

The invention discloses a method and a system for driving RS422 communication of a CPCI (Compact Peripheral Component Interconnect) bus in a Windows xp system. The system comprises a Windows xp bottom driving program, an inf file, a dll program and a top function test application program, wherein the top test application program is used for calling an API interface function provided by the dll program; the dll program is used for providing the API interface function needed for communication of the top function test application program and the bottom driving program; the inf file is used for providing resource information needed for installing a driving system; the Windows xp bottom driving program comprises a driving program entry function DriverEntry, an AddDevice manager calling function and an IRP dispatch function. The system has the characteristics of modularization and stratification, and supports plug and play; the top function test application program accesses hardware via a specification mode without consideration on control over details of the hardware.
Description
technical field [0001] The invention belongs to the technical field of CPCI bus driving, in particular to a method and system for driving CPCI bus RS422 communication under the Windows XP operating system. Background technique [0002] Compact PCI is an open, international industrial computer standard. It combines many widely verified standards of computers and industrial equipment, and is a combination of PCI bus technology and mature European card assembly technology. The CPCI bus has the characteristics of high openness, high reliability, and hot pluggability. Compared with traditional industrial PCs, it has the advantages of durability, shock resistance, and ventilation. In addition to being widely used in communications, networks, and computer telephony integration, CPCI bus technology is also suitable for real-time system control, industrial automation, real-time data acquisition, and military systems that require high-speed computing, intelligent transportation, aero...
