LabVIEW-based data acquisition system design

In order to achieve the purpose of data collection, save and analyze. In this paper, through the LabVIEW-based platform, we designed a set of signal acquisition and storage playback in one virtual data acquisition system, under the premise of the microcontroller through the serial port to send data signals, storage and playback waveforms which has been collected, Both with waveform spectrum analysis function and the functions of traditional data acquisition, The user can set the waveform operation and playback speed, and gives the design diagram and simulation results.
