library package
2.I discussed the general method of building Dynamic Linked Library (DLL) in Ch environment in this chapter. After the device driver & application software package have been packed and built to a DLL in Ch, I implemented a Web-based data acquisition using AT-MIO-16E-10 DAQ board from NI Inc. This method has been used in a test bed of belt transmission.
4.Virtual instruments delegate the direction of instruments. Conform the trend of instrument development, in this thesis the author adopts Lab Windows/CVI software development environment based on ANSI C library, using skillfully DLL technique, develops virtual signal generation, virtual display instrument respectively based on sound card and ACL-8111 data acquisition card, part of advanced arithmetic about inline signal such as small wave analysis, small wave package analysis and BP nerve network.
