Design of a high speed data acquisition system based on DSP and MAX1420

Xiaoping Li

Abstract

This paper introduces the status of the data acquisition system,analyses the function demands of the high speed data acquisition system,and accomplishes the corresponding design scheme.The hardware of the system frame and the circuits of the main module are given in detail.The structure of the system software and the flow-chart of the main program are explained.In this system,MAX1420 is used as the analog to digital converter,DSP(TMS320C6713)as the CPU,FT245BM to realize the USB2.0 interface function,and large-capacity memorizer to backup the sampling data.The system testing shows that the system can real time complete the data acquisition and storage.
