mechanical design;  Courses;  experimental systems;  Microcomputer;  Dynamic link libraries

The hardware composition and software module functions of the experimental system using the "mechanical design" course of microcomputer development are systematically introduced, and the methods of VC++ to create dynamic link libraries and VB to call dynamic link libraries used in acquisition program design are specifically explained. The system improves the measurement accuracy, simplifies the data processing process, and can print out experimental reports and curves, and the user interface is simple.
