EPP高速数据采集与LabVIEW接口实现

High-speed EPP Sampling with LabVIEW Interface

介绍了 EPP高速数据采集的方法及其在 L ab VIEW下的接口实现。通过直接对端口的操作 ,可以用 L ab VIEW直接产生 EPP读写时序 ,配合外部 F IF O和握手电路 ,完成地址的写出与数据的读入。再利用 L ab VIEW本身的图形工具 ,可以方便地构成数据的波形显示及对数据的各种处理。

This paper introduces how to realize highspeed EPP sampling with LabVIEW interface. LabVIEW can direct form EPP read or write circle through direct IO operation. With hardware FIFO and handshaking circuit, address can be write out and data can be read into memory. Using LabVIEW graphic tools, it is easy to show data wave or to do more data processing.
