TMS320F2812-based high-speed simultaneous signal acquisition system design and realization

为了实现高速同步数据采集,设计了了一种基于TMS320F2812 DSP芯片与AD转换芯片ADS8364构成的并行高速、高精度数据采集系统.主要包括硬件接口电路的设计,控制参数的设置以及部分关键的控制代码和实现AD采样的程序流程等.调试证明,本系统是一种新颖、采集精度高并且易于实现、配置灵活的数据采集系统.

In order to implement high-speed simultaneous data collection, a high speed and high precision simultaneous data acquisition system is designed based on composed TMS320F2812 DSP chip of TI and AD converters ADS8364. The inter/ace of designing hardware connection, setting parameter of comrol and the key code of software and flow process diagram of AD sample are mainly described. It is proved that the new data collection system has the advantages of high precision, easy to realized.
