Single Chip Microcomputer Experiment Platform Development Based On Virtual Instrumeat

SCM techinology application as a practical course,must be equipped with correspondingexperiment equipment can obtain satisfied teaching effect. Have a comprehensiveexperimental platform can be smoothly carried out the experiment teaching is animportant prerequisite, currently existing experimental teaching in colleges anduniversities most components easy to damage the device, device features a single,repetitive low utilization rates, extended properties such as problems. Beginning in1999,the major colleges and universities enrollment goes up, a sharp increase in the numberof students. And many universities are mainly teaching as the main tasks, based on thecosts of running and actual conditions is impossible to introduce advanced laboratoryequipment for teaching, does not match the needs of the teaching of experimentalteaching equipment and had not been well addressed, particularly prominent in thissituation in higher vocational colleges.Advanced virtual instrument technology, in line with the international "hardware andsoftware" trend, often called "software instrument". It is powerful, you can implement avariety of instruments such as Oscilloscopes, signal generators, spectrum instrumentfunction, are we good means to improve equipment performance.Paper is based on the status of the virtual instrument technology to build single-chipexperiment teaching platform and the application of the results in the SCM course.The main work of the paper:(1)Research platform features of the existing single-chip experiments, and analyze itssuccess and deficiencies.(2)Describes the stages of development and benefits of virtual instrument technology,make the direction of research on the subject is the application of virtual instrumenttechnology on the single-chip microcomputer experimental teaching. On theconstruction of virtual instrument technology and software development tools aredescribed in detail.(3)The experimental teaching system design. The System is composed of a generalanalog measllre and control module，a general switch measure and comtrol module，ageneral pulse measure and control module,which constitine a set of SCM experimemsystem based on the virtual.(4)Summary and Prospect.
