實(shí)驗(yàn)6 數(shù)碼管譯碼驅(qū)動(dòng)電路的設(shè)計(jì)(解答)

1、1實(shí)驗(yàn)實(shí)驗(yàn)6數(shù)碼管譯碼驅(qū)動(dòng)電路的數(shù)碼管譯碼驅(qū)動(dòng)電路的并行語(yǔ)句設(shè)計(jì)并行語(yǔ)句設(shè)計(jì)一、一、實(shí)驗(yàn)?zāi)康膶?shí)驗(yàn)?zāi)康?了解7段數(shù)碼管的驅(qū)動(dòng)方式，設(shè)計(jì)數(shù)碼管驅(qū)動(dòng)電路，輸入一位整數(shù)，把整數(shù)譯碼，通過(guò)數(shù)碼管顯示；2利用并行信號(hào)選擇語(yǔ)句設(shè)計(jì)數(shù)碼管驅(qū)動(dòng)電路；二、二、實(shí)驗(yàn)要求實(shí)驗(yàn)要求1數(shù)碼管譯碼驅(qū)動(dòng)電路可分為輸入模塊和譯碼模塊兩部分，電路系統(tǒng)結(jié)構(gòu)圖如下：2四個(gè)按鍵與電路的輸入端口num1、num2、num3、num4相連，可向電路輸入一個(gè)整數(shù)data。3譯碼模塊對(duì)

2、整數(shù)data進(jìn)行譯碼產(chǎn)生7位譯碼信號(hào)data_out，驅(qū)動(dòng)數(shù)碼管顯示整數(shù)的數(shù)值。三、三、實(shí)驗(yàn)步驟實(shí)驗(yàn)步驟1根據(jù)實(shí)驗(yàn)電路的要求，請(qǐng)寫(xiě)出電路的硬件框圖。根據(jù)實(shí)驗(yàn)電路的要求，請(qǐng)寫(xiě)出電路的硬件框圖。譯碼模塊datadata_outnum1輸入模塊num2num3num436.數(shù)碼管驅(qū)動(dòng)碼對(duì)照表為：數(shù)碼管驅(qū)動(dòng)碼對(duì)照表為：整數(shù)驅(qū)動(dòng)碼(g、f、e、d、c、b、a)整數(shù)驅(qū)動(dòng)碼(g、f、e、d、c、b、a)001111115110110110000110
