摘要
针对在自动控制系统设计领域和通信领域中有着广泛运用的AD7862芯片,介绍了一种基于FPGA的驱动接口电路的设计。阐述了AD7862的特点及基本功能,以及基于这些功能特点的驱动时序,并以此时序为基础在FPGA芯片中实现了AD7862的驱动电路。给出了主要的VHDL代码以及最终的仿真测试结果,实现了对AD7862芯片的稳定可靠驱动,同时也验证了所设计驱动电路的正确性。
The AD7862 chips have an extensive usage in the automatic control system design field and communication field.An electric circuit interface based on FPGA is introduced in this paper.The basic function and characteristics of AD7862 and it＇s time diagram based on these function and feature are elaborated.VHDL code,final imitation and test result are given in this thesis.At last,a stability drive to the AD7862 chips is realizes and verified the accuracy of the driving electric circuit designed at the same time.
