【導(dǎo)讀】單片機是隨著超大規(guī)模集成電路技術(shù)的發(fā)展而誕生的。單片機片內(nèi)集成的功能越來越強大，并朝著SoC方向發(fā)展?？梢园l(fā)現(xiàn),單片機的應(yīng)用與開發(fā),在時代發(fā)展中所占的重要位置。以一簡易的低頻信號設(shè)計為例，了解單片機的基本原理。信號可通過按鍵選擇輸出,輸出信號的頻率可以從范圍內(nèi)調(diào)整.作為D/A轉(zhuǎn)換器功能按鍵使用單片機的三個端口。口須外接上拉電阻。作方式，以及片內(nèi)振蕩器和時鐘電路。應(yīng)用，如機電式或電子式電度表，智能煤氣表，測速儀等智能儀器。電壓,高性能8位CMOS微型計算機。它采用ATMEL的高密非易失。存儲技術(shù)制造并和工業(yè)標準MCS—51指令集和引腳結(jié)構(gòu)兼容。上組合通用的CPL1和閃速存儲器,ATMELAT89C2051是一強勁的微型計算機,它對許多嵌入式控制應(yīng)用提供一高度靈活和成本低的解決辦法。
