1、印張計數(shù)器設(shè)計一設(shè)計任務要求1能夠進行6位數(shù)碼顯示，顯示當前的印張數(shù)；2能夠進行印數(shù)的預置；3能夠進行正/反計數(shù)；4能夠模擬機械手取出次品；5當計數(shù)結(jié)束時，可以報警；二硬件設(shè)計總圖80c514個led顯示印張計數(shù)器運作狀態(tài)鍵盤輸入端口6個七段數(shù)碼管顯示數(shù)據(jù)復位監(jiān)控輸入印張計數(shù)中斷信號輸入晶振時鐘輸入電源led指示燈三硬件部分分析說明1）、顯示部分實驗箱提供了6位8段碼led顯示電路，只要按地址輸出相應數(shù)據(jù)，就可以實現(xiàn)對顯示器的控制。顯示共有6位，用動態(tài)方式顯示。8位段碼、6位位碼是由兩片74ls374輸出。位碼經(jīng)mc1413或uln2003倒相驅(qū)動后，選擇相應顯示位。在實驗箱中8位段碼輸出地址

2、為0x004h，位碼輸出地址為0x002h。此處x 是由key/led cs決定，參見地址譯碼。做鍵盤和led實驗時，需將key/led cs 接到相應的地址譯碼上。以便用相應的地址來訪問。將key/led cs接到cs0上，則段碼地址為08004h，位碼地址為08002h。2）、鍵盤部分1 預設(shè)初始計數(shù)值：可通過數(shù)字鍵鍵入所需計量的印張數(shù)，按下“確定（a）”鍵后開始。2 正向反向計數(shù)：可通過鍵盤上的正向（b）反向（c）鍵切換正向計數(shù)或者反向計數(shù)。當選擇正向計數(shù)時，顯示屏顯示從0開始，每印刷一張，數(shù)值加1，直到遇到暫?；蛘叩竭_預設(shè)值時停止計數(shù)；當選擇反向計數(shù)時，顯示屏從預設(shè)值開始，每印刷一張，

3、數(shù)值減1，直到遇到暫停或者到達0時停止計數(shù)。3次品報告：當按下鍵盤上次品鍵（d）時，代表出現(xiàn)次品，此時直流電機停止運轉(zhuǎn)，步進電機緩慢轉(zhuǎn)動一周，代表機械手取出次品，之后直流電機恢復運轉(zhuǎn)。 4 報警提示：當計數(shù)為0或者到預設(shè)值時，停止計數(shù)，發(fā)出報警，此時l2亮。 5 復位鍵（f）78945 6 1 2 3 0feabcd確定正計反計次品 數(shù)字復位顯示屏四源程序#include <reg51.h>#define ledlen 6/用6個八段管xdata unsigned char outbit _at_ 0x8002; / 位碼輸出+列掃描地址xdata unsigned char ou
