基于FPGA的微型示波器设计

Design of Micro Oscilloscope Based on FPGA

基于现场可编程逻辑门阵列(Field Programmable Gate Array,FPGA)作为处理器,辅以高速AD/DA模块和RGBLCD显示屏的微小型示波器,使用Quartus Prime集成开发环境进行软件开发,通过AD9280对外部信号进行采集,传输数据到处理器FPGA并使用液晶显示器(Liquid Crystal Display,LCD)显示结果,实现微型示波器的功能。可以简化老式示波器的操作,降低操作难度,改变以往大型机器的状况,提高示波器的使用和携带能力,大大节约成本。

A miniature oscilloscope based on Field Programmable Gate Array(FPGA)as the processor,supplemented by high-speed AD/DA module and RGBLCD display screen.It uses the Quartus Prime integrated development environment for software development,collects external signals through the AD9280,transmits data to the processor FPGA and displays the results using the Liquid Crystal Display(LCD)screen to realize the function of the miniature oscilloscope.It can simplify the operation of the old oscilloscope,reduce the difficulty of operation,change the condition of the previous large machines,and improve the use and carrying capacity of the oscilloscope,which can also greatly save costs.
