【正文】 變?yōu)榈碗娖?，按照軟件的設(shè)定：從此刻起禁止對行進行數(shù)據(jù)傳輸；同理，當顯示棒擺到右邊極點時，與 3 接觸，與此相連的 口變?yōu)榈碗娖剑浖O(shè)定從此刻起數(shù) 5 據(jù)開始傳輸。它的最小系統(tǒng)包括晶體振蕩電路、復(fù)位開關(guān)和電源部分。如果慣性開關(guān)位于右邊，則進入外部中斷 T1 并將一變量置 1。之后再立刻熄滅 LED 并開始重新判斷慣性開關(guān)的位置 （整體流程圖見圖 4） 。 軟件實現(xiàn)功能的完善 本次設(shè)計的一個難點是去除 重影，我們的解決方法是使用外部中斷讓數(shù)據(jù)單程傳輸。 5 系統(tǒng)測試 設(shè)計要求部分的測試 基本顯示部分： 能夠清晰的顯示并辨認出“ A”、“電 ”以及五環(huán) ，可以通過按鍵進行內(nèi)容的切換。 設(shè)置外部電源插針， 在不使用電池供電時可以利用插針進行外部供電。這些創(chuàng)新點的增加都為 8 本次設(shè)計增添不少趣味性和實用性。在討論中我們不斷的完善我們的方案，對每個組員提出的問題都仔細的分析推敲。//74ls595 時鐘信號 sbit so=P3^5。//鍵盤標準 unsigned char flag。 unsigned char code Wele[7*32]={ 0xFF,0xFF,0xFF,0xFF,0xFF,0xB7,0xFF,0x37,0xFE,0xBB,0xFE,0xBB,0xFE,0xBB,0xFE,0xBB, 0xFE,0xBB,0xFE,0xBB,0xFE,0xB3,0xFF,0x37,0xFF,0x07,0xFF,0x8F,0xFF,0xFF,0xFF,0xFF,//e 0xFF,0xFF,0xFF,0xFB,0xFE,0x03,0xFE,0x03,0xFE,0xFB,0xFE,0xFF,0xFE,0xFB,0xFE,0x03, 0xFE,0x03,0xFE,0xFB,0xFE,0xFF,0xFF,0x7B,0xFE,0x03,0xFE,0x03,0xFE,0xFB,0xFF,0xFF,//m 0xFF,0xFF,0xFF,0x8F,0xFF,0x07,0xFF,0x77,0xFE,0x73,0xFE,0xFB,0xFE,0xFB,0xFE,0xFB, 0xFE,0xFB,0xFE,0xFB,0xFE,0x73,0xFF,0x77,0xFF,0x07,0xFF,0x8F,0xFF,0xFF,0xFF,0xFF,//o 0xFF,0xFF,0xFF,0xFF,0xFF,0xF7,0xFF,0x77,0xFE,0x7B,0xFE,0xFB,0xFE,0xFB,0xFE,0xFB, 0xFE,0xFB,0xFE,0xFB,0xFE,0x7B,0xFF,0x77,0xFF,0x07,0xFF,0x8F,0xFF,0xFF,0xFF,0xFF,//c 0xFF,0xFF,0xFF,0xFF,0xFF,0xFF,0xFF,0xFB,0xFF,0xFB,0xFF,0xFB,0xFF,0xFB,0xE0,0x03, 0xE0,0x03,0xEF,0xFB,0xEF,0xFB,0xEF,0xFB,0xEF,0xFB,0xFF,0xFF,0xFF,0xFF,0xFF,0xFF,//l 11 0xFF,0xFF,0xFF,0xFF,0xFF,0xB7,0xFF,0x37,0xFE,0xBB,0xFE,0xBB,0xFE,0xBB,0xFE,0xBB, 0xFE,0xBB,0xFE,0xBB,0xFE,0xB3,0xFF,0x37,0xFF,0x07,0xFF,0x8F,0xFF,0xFF,0xFF,0xFF,//e 0xEF,0xFF,0xEF,0xFF,0xE1,0xFF,0xEE,0x3F,0xFF,0xC7,0xFF,0x83,0xEC,0x0F,0xE0,0x7F, 0xE0,0x7F,0xEF,0x1F,0xFF,0xE7,0xEF,0x83,0xE8,0x0F,0xE0,0x7F,0xE3,0xFF,0xEF,0xFF,//W }。 unsigned char code huihui[64]={ 0xFC,0x00,0xCE,0x00,0xC7,0x00,0x83,0x80,0x81,0x80,0x81,0xFE,0x00,0xFF,0x1C,0xE3, 0x3C,0xC1,0x18,0xE3,0x00,0x7F,0x00,0x7E,0x80,0x60,0xC0,0x60,0xE0,0xC0,0xF0,0xC0,//上半身，可以顯示印章的 0x00,0x03,0x07,0x81,0x0F,0xE0,0x1F,0xE0,0x3C,0xF1,0x78,0x3F,0x70,0x1F,0xE0,0x0F, 0xFC,0x00,0xFF,0x00,0x07,0x80,0x03,0xC1,0x3F,0xC1,0x3F,0x81,0x30,0x03,0x10,0x0F,//下半身 }。 void Delay(unsigned int delaytime)。 void xiao_lian()。 flag=0。//第一次進中斷 } 14 void main(void) { a=1。 PX1=0。//啟動外部中斷 0 EA=1。P2=0xff。i+=2) { P0=Wele[i1]。//讓兩個字之間留有空隙，顯示時不會一個接一個 } else if(ID==3) {//橫著顯示 美亞 for(i=1。 Delay(100)。send8bit(0xff)。i+=2) { P0=wuhuan[i1]。//P0=0xff。 } Delay(500)。i=31。 send8bit(dian[i])。 P1=A[i1]。 P2=dianzi[i]。//豎著顯示 電子 case 6: P0=huihui[i1]。 break。break。P2=0xff。 if(k==50) { k=0。send8bit(0xff)。 P2=moving_people[i]。amp。send8bit(moving_people[i+96])。 P2=xiaolian[i]。P2=xiaolian[i+32]。 send8bit(wuhuan[i+68])。 send8bit(wuhuan[i+136])。 if(ID==9) { ID=0。q8。//寄存器時鐘上跳沿，將一位數(shù)據(jù)存入移位寄存器。 } 附錄 4：顯示圖案效果圖
