摘要
设计了一种基于TMS320LF2407A型DSP芯片和14位AD芯片MAX125的谐波实时采集计算系统。设计了硬件电路,包括DSP最小系统、AD转换系统以及相关的辅助电路。给出了数据采集及AD转换的软件程序。经过实验验证,该装置具有良好的性能,而且结构简单,成本低廉,将得到广泛的使用。
A real-time harmonic acquisition and measure system based on the DSP chip TMS320LF2407A and the14bits A/D chip MAX125 is presented .This paper designs the hardware circuit, including DSP circuit and AD convert system. Given the program which the data acquisition and AD transform. The result shows that this system has the good characteristics ,and low cost. This system will be widely used.
