摘要
文中设计基于USB接口的主从式数据采集系统。PC机作为主控机,进行可视控制、实时显示等操作;DSP实现电极选通、数据采集及预处理并控制USB接口芯片与PC机进行数据通讯。测试结果表明,该数据采集系统的数据传输速率明显提高。
In This paper, how to design a computer peripheral via B, and demonstrates master-slavedata acquisition system based on USB are discussed. The master PC performs the visual control and real-time display, while DSP controls electrode selection, data acquisition, pre-processing and data communication with the master. The test results show that the transmitting date speed of the acquisition system is markedly implcyed.
