Abstract
Data acquisition (DAQ) is a process of bringing a real world signal in to the computer for processing, analysis, storage or other data manipulation. Here in this paper not only the process of data capture from real world in real time, also the process of data feed to real world in real time from computer in different format is also discussed with a developed user friendly Graphical User Interface (GUI) in Visual Basic platform. To control any parameter of a device it is necessary to have the real time data of that parameter in the controller. Also, to control the device it is required to feed some data back to the real world after some processing of the captured data. Here in this paper capturing and feeding of data with user friendly GUI is developed with the help of PIC16F877A microcontroller.
