Abstract

As an important part of signal processing,the data acquisition system realizes acquisition,storage and recovery of analog signals. In this paper,the LM3S9B96 main controller adopting Cortex-M3 core is used to build a data acquisition card with dual-channel data acquisition function. For the purpose of fast efficient data transmission,the universal serial bus(USB) technology is used to fulfill data transmission from the acquisition card to the host computer. LabVIEW development platform integrating data processing,waveform display and waveform analysis is chosen to process signals in the host computer,thus meeting the design requirements in every respect.
