A Single-chip Multi-channel Data Acquisition System Based on LabVIEW

This paper introduces a multi-channel data acquisition system based on LabVIEW by using the concept of virtual instrument.A MSP430F149 single-chip microcomputer system is used for data acquisition,and the monitoring interface of the host computer is developed by using the LabVIEW.An alarm function is also added to the system,and the alarm threshold can be set on the monitoring interface of the PC.
