Evaluación y mejora a tarjeta USB de adquisición de datos para LabVIEW

Abstract

The acquisition of data will become the main factor for the growth of the I4.0 and the IOT, so an evaluation and proposals for improvement to the USB data acquisition card for LabVIEW, reported in the journal of Computational Systems and ICT's in March 2016, are presented. The use of Arduino for the acquisition of data is popular, but its hardware architecture and programming structures already resolved, prevents its users from developing their own knowledge. The previously reported card has the disadvantage of being centered on a single SubVI that hinders the interconnection of elements and the generation of complex programming schemes. Looking for ease of use, a redesign of the PCB functional in Windows 10 and that allows its direct connection to protoboard has been done; in addition, individual SubVI’s were developed for data acquisition tasks, which can be used repeatedly in LabVIEW and which can be integrated into their libraries. A web page has been created where files are shared in free code, diagrams, examples and other tutorials. The new card and its libraries are simpler to use, have greater versatility and allows interaction with peripheral hardware.
