摘要
针对TMS320F2812难以对多路信号进行同步采样,介绍了一种基于AD转换芯片ADS8365与TMS320F2812 DSP芯片构成的高速、并行高精度数据采集系统,包括硬件接口电路的设计、部分关键程序代码和实现AD采样的程序流程。
Aiming at the difficulty of realizing multi-channel signals synchronized sampling using TMS320F2812, this paper introduces a high-speed, high-precision simultaneous data acquisition system, which is built based on two main modules： AD converter of ADS8365 and TMS320F2812 DSP chip of TI, including the design of hardware interface circuits, some critical program code and the flowchart of AD sampling program.
