摘要
介绍一种基于FPGA的数据采集系统的设计,以CycloneⅡ系列的EP2C35F484芯片为主控单元,配合模数转换芯片ADS7825和USB传输控制芯片CY7C68013,并结合外围电路实现了采集系统。基于QuartusⅡ9.0平台,实现了对ADS7825芯片和CY7C68013芯片的控制与通信,并采用Verilog硬件描述语言,实现了系统的仿真,给出了系统核心模块的时序仿真波形图。经测试,系统实现了对多路模拟信号的采集,具有良好的稳定性、快速性。
Introduces a data acquisition system based on the FPGA design , by using Cyclone Ⅱ series of EP2C35F484 chip as the master control unit, with the A/D conversion chip ADS7825 and USB transmission control chip CY7C68013, and combined with peripheral circuit realized the acquisition system. Based on the Quartus Ⅱ 9.0 flat, to realize the ADS7825 chip and CY7C68013 chip control and communication, we use the Verilog hardware description language to realize the simulation of the sys-tem, and give the system core module timing simulation waveform diagram. By test, the multi-channel analog signal acquisition, has a good stability and rapidity.
