在開放式數(shù)控系統(tǒng)結(jié)構(gòu)模型的基礎(chǔ)上，研究了基于ISA總線的DSP通信控制原理。采用中斷方式完成了PC機(jī)和DSP之間的通信。介紹了以DriverWorks為工具開發(fā)ISA設(shè)備WDM驅(qū)動(dòng)程序的方法，探討了中斷處理、驅(qū)動(dòng)程序與應(yīng)用程序之間的通信,簡要說明了驅(qū)動(dòng)程序的安裝與調(diào)試。通過調(diào)試,系統(tǒng)設(shè)計(jì)運(yùn)行穩(wěn)定。
Abstract:
The ISA bus and DSP correspondence control principle is investigated in the basis of the existing open architecture numerical control system.The interrupt method is used to realize the communication between PC and DSP based on the ISA bus.The methods of WDM driver exploitation for ISA device using Driver Works are introduced.The main process of driver program and the keys such as handle interrupt and the communication between the drivers and application are presented.And how to debug and install the drive is explained.
