摘要
设计了一种基于TI公司生产的TMS320LF2407 DSP芯片和14位A/D芯片MAX125的实时数据采集系统。设计了硬件电路的核心部分:电流电压的信号处理电路和AD转换控制电路。详细介绍了AD转换的控制和实现过程的软件实现方法。最后对该数据采集系统进行了测试,结果表明该系统在精度、采集速度和同步采样方面具有良好的性能,且结构简单,成本低廉。该系统将得到广泛的使用。
A real-time data acqusition system based on thel4bits A/D chip MAX125 and the DSP chip TMS320LF2407 made in TI incorporation is presented. This paper designs the core of the hardware circuit, including signal processing circuit and control circuit of AD convert.The software realization method of AD conversion and control process is detailed.And the result shows that this system has the characteristics of fine performance in precision, high-speed and synchronous sampling plus its simple design and low cost.This system will be widely used
