Design and realization of a TMS320F2812-based high-speed simultaneous signal acquisition system

为了实现高速同步数据采集,本文介绍了一种基于TMS320F2812 DSP芯片与AD转换芯片ADS8364构成的高速、并行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。实践证明,本系统是一种比较新颖、采集精度高并且易于实现、配置灵活的数据采集系统。

To implement high - speed simultaneous data collection, we designed a high - speed, high - precision simultaneous data acquisition system, which is built based on two main modules： TMS320F2812 DSP chip of TI and AD converter of ADS8364. The design of hardware interface circuits, setting of control parameters, some critical control code, and the flowchart of AD sampling program etc. are describod in this paper. Practice proved that the system is a comparatively new data acquisition system easy to realize, which has high acquisition accuracy and flexible configuration.
