并行IO接口試驗報告

1、并行I/O接口實驗報告一、實驗目的1 .掌握GPIOIP核的工作原理和使用方法。2 .掌握IO接口程序控制方法3 .掌握中斷控制方式的IO接口設計原理4 .掌握中斷程序設計方法二、實驗任務使用查詢、中斷兩個方式做獨立式開關輸入，將開關的狀態(tài)顯示到console。三、硬件平臺建立1.硬件框圖2.通過xps建立最小系統(tǒng)，打開system.xmp文件0此®M陶頓“更片國鄴，下我Ji音樂一匚1常_軟件(DO池任：)一f(F:)gen日impactbatchBlbitinit1clock_generator_0flPtgenHIplatgen.opt§psf2EdwardsyEter
