Abstract

In this work a data acquisition board (DAQB) with data transfer by parallel port LPT and the associated virtual library included into LabVIEW software are presented. The DAQB developed around a National Semiconductor LM 12458 device, have the capability to perform tasks that diminish the host processor work and is capable to communicate with the host computer by using a set of drivers associated. Highly integrated device circuit that has into it the most components of the board, facility in data handling, good metrological performance and a very low cost are the benefits of the proposed system. The novelty of the system consists in the drivers associated that assure the flexibility and the portability of the system and in the fact that you can plug-in the DAQB to the running host computer externally.
