Abstract

The integration of personal computers with the present-day measurement and instrumentation world has opened up the door for "virtual instrumentation." Virtual instruments are centered on a PC and used with as little specialized hardware as possible to link it to the devices it must measure/control. This project is about to develop a low-cost, PC-based virtual instrumentation. It is a data acquisition device by using the parallel port and has been fabricated with full analog interface and 8-bit analog to digital converter with associated control-logic and timing circuitries. This virtual instrumentation is a simple plug-in board and incorporated with any ffiM PC parallel port, thus in many cases the output are similarly same with multiple and expensive digital Oscilloscope. The requirement system for the PC is Pentium Processor, preferably 32-M RAM with have Windows 95/98 or higher operating system. This project is developing by using Visual Basic and C programming. In addition as an idea, several other menu-driven functions for data-storage, display, analysis, and printing can also be demonstrated.
