摘要
Abstract
The design of high speed and stable data collection system is based on FTDI’s USB2.0 communication chip FT2232H and FPGA. Time division multiplexing is used in analog signal acquisition. Using FPGA as system’s control core,FT2232H as USB controller and two SARAMs as data buffer,combined with A/D model the data col-lection system has been composed. The operation of data collection,data cache and data transfer are carried out par-allel in FPGA,transmission speed is 6.8 Mbyte/s,so that the data collection and tranfer efficiency are improved. The data collection system based on FT2232H has the advantages of high speed and stable in the experiment.关键词
