1、.摘要近年來隨著科技的飛速發(fā)展,單片機(jī)的應(yīng)用正在不斷地走向深入,同時帶動傳統(tǒng)控制檢測日新月異更新。在實時檢測和自動控制的單片機(jī)應(yīng)用系統(tǒng)中,單片機(jī)往往是作為一個核心部件來使用,僅單片機(jī)方面知識是不夠的,還應(yīng)根據(jù)具體硬件結(jié)構(gòu),以及針對具體應(yīng)用對象特點的軟件結(jié)合,加以完善。正文首先介紹本課題的背景、研究意義及完成的任務(wù)功能;接著簡單描述設(shè)計過程中所用的一些主要元器件、方案的論證,以及介紹了系統(tǒng)硬件工作原理,并且附以系統(tǒng)硬件設(shè)計框圖;其次闡述了PCB板的畫質(zhì)、制作、實物的完成、程序的編寫和調(diào)試;最后對本設(shè)計進(jìn)行了總結(jié)。本次畢業(yè)設(shè)計根據(jù)設(shè)計要求,基
