一种基于DSP技术的超声波数据采集设计

Design of Ultrasonic Data Acquisition System Based on DSP

提出了一种基于DSP技术的数据采集系统,该系统使用高速AD转换芯片和DSP芯片,利用DSP芯片的PWM模块作为AD采样时钟,数据接口采用16位数据总线方式,通过DMA控制的方式实时读取采样数据。实验结果表明,该系统满足数据实时采集的需要。

A new kind of data acquisition system based on DSP and high speed AD converter is designed in this paper.In this system,Clock input of AD converter is generated by PWM module.AD converter is designed with 16 bits parallel interface,and the DMA module of DSP is designed for data communication.The experiment results indicated that,this system meet the needs of real-time data acquisition.
