Design of driver program based on EPP parallel port under Windows system and its application in the distributed seismometer
Jun Lin · Journal of Changchun Post and Telecommunication Institute · 2004
WDM(Windows Driver Module) has been put forward because there is no directly ways to manipulate hardware under Windows 2000. Being part of the core of operation system, WDM works in Ring0 level, and makes the access to hardware quick. Example of exploitation high-speed distributed system based on EPP(Enhanced Parallea Port) was introduced.The principle, module structure, detail approach and designing methods by DriverWorks are discussed.1 Mbit/s transmission speed between master computer and slave computer is realized. Now, it is applied in distributed seismometer successfully,and makes field works quite convenient.
