采用Intel8255端口數(shù)據(jù)線與上圖除IN0~IN7之外的引線連接。 程序步驟： (1)根據(jù)模擬信號輸入連線方式(跳線JP10與電位器１相連，若JP10上跳線摘掉，可將電位器２作模擬信號輸入)，選擇模擬通路，即選定addC,addB,accA組成三位二進(jìn)制數(shù)據(jù)； (2)同時(shí)使START和ALE有效，使ADC0809選擇相應(yīng)模擬信號并轉(zhuǎn)換； (3)等待EOC出現(xiàn)高電平； (4)使OE為高電平，即允許從ADC0809讀出數(shù)據(jù)

ADC0809采樣控制電路的實(shí)現(xiàn)ADC0809是CMOS的8位A/D轉(zhuǎn)換器，片內(nèi)有8路模擬開關(guān)，可控制8個(gè)模擬量中的一個(gè)進(jìn)入轉(zhuǎn)換器中，轉(zhuǎn)換時(shí)間約100us。主要控制信號有，START是轉(zhuǎn)換啟動(dòng)信號，高電平有效。ALE是3位通道選擇地址（ADDC、ADDB、ADDA）信號的所存信號。當(dāng)模擬量送至某一輸入端（如IN1或IN2），由3位地址信號選擇，而地址信號由ALE鎖存。
