【正文】 謝珠江學院在我四年的大學生活當中對我的教育與培養(yǎng)，感謝珠江學院信息工程系的所有專業(yè)老師，沒有你們的辛勤勞動，就沒有我們今日的滿載而歸，感謝大學四年曾經幫助過我的所有同學。在制作畢業(yè)設計過程中我曾經向老師和同學們請教過不少的問題，老師的熱情解答和同學們的熱心幫助才使我的畢業(yè)設計能較為順利的完成。在此我向你們表示最衷心的感謝。 25附 錄 附錄 A 硬件原理圖 硬件原理如圖 A 所示：圖 A 硬件原理圖 26附錄 B 仿真程序 仿真的程序如下： include include define uint unsigned int define uchar unsigned char define NOP() _nop_() sbit EN_port = P1^3。 sbit DA_in_port = P1^2。 sbit CLK_port = P1^1。 sbit Latch_port = P1^0。 define ABCD_port P1 //HC138 ABCD 端口定義 //sbit D_port = P1^7。 //sbit C_port = P1^6。 //sbit B_port = P1^5。 //sbit A_port = P1^4。 uchar code ziku_table[]= { 0xFB,0xFF,0xF7,0xFF,0x37,0xC0,0xFF,0xFD,0xEE,0xFD,0xED,0xFD,0xF5,0xFD,0xF7,0xFD, 0xF7,0xFD,0xFB,0xFD,0xF8,0xFD,0xFB,0xFD,0xFB,0xFD,0x0B,0x80,0xFB,0xFF,0xFF,0xFF,/*江,0*/ }。 uchar data disp_buff[14]。 /* 點陣 LED 第幾行顯示數(shù)據(jù) void HC595_Data_Send(uchar *p,han,zishu){uchar i。uchar data_buff,temp=0。Latch_port = 0。 /*HC595 鎖定輸出,避免數(shù)據(jù)傳輸過程中，屏數(shù)據(jù)變化從而顯示閃爍*/CLK_port = 0。for(。zishu0。zishu) {data_buff = p[temp]。temp++。for(i=0。i8。i++) {if((data_buffamp。0x80)!=0) DA_in_port = 1。else DA_in_port = 0。CLK_port = 1。 27CLK_port = 0。data_buff = 1。}data_buff = p[temp]。temp++。for(i=0。i8。i++) {if((data_buffamp。0x80)!=0) DA_in_port = 1。else DA_in_port = 0。CLK_port = 1。CLK_port = 0。data_buff = 1。}}EN_port = 1。 /*關屏顯示，原理為使 HC138 輸出全為 1，從而三極管截止，點陣不顯示*/ABCD_port = (ABCD_port amp。 0x0f)|(han4)。Latch_port = 1。 /*允許 HC595 數(shù)據(jù)輸出到 Q1Q8 端口*/EN_port = 0。 /*HC138 輸出有效，打開顯示*/Latch_port = 0。 /*鎖定 HC595 數(shù)據(jù)輸出*/}void main(){uchar j=0。 /*讀取對應的第幾行數(shù)據(jù)*/while (1){ disp_buff[1]=ziku_table[j*2]。 //H8disp_buff[0]=ziku_table[j*2+1]。 //L8HC595_Data_Send(disp_buff,j,1)。j++。 /*行加 1*/if(j==16) j=0。}} 28附錄 C 設計源程序include include define uint unsigned intdefine uchar unsigned chardefine NOP() _nop_()sbit EN_port = P1^3。 //138 使能端sbit DA_in_port = P1^2。 //595 串口輸入端sbit CLK_port = P1^1。 //595 時鐘sbit Latch_port = P1^0。 //595 顯示端define ABCD_port P1 //HC138 ABCD 端口定義//sbit D_port = P1^7。//sbit C_port = P1^6。//sbit B_port = P1^5。//sbit A_port = P1^4。uchar disp_han。 //目前顯示的行數(shù)uchar move1。 //對于上移移動的次數(shù)uint word。 //字模計數(shù)器uchar move。 //列指針uchar line。 //行指針uchar speed=5。 //設定移動速度uchar buf[12]。 //緩存數(shù)組uchar code disp0[]={ //左移字庫0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0x7F,0xFF,0x7F,0xFF,0xBF,0xFF,0xBF,0xFF,0x1F,0xF8,0xEF,0xFB,0xEF,0xFB,0x0F,0xFB,0xEF,0xFB,0xEF,0xFB,0x0F,0xFB,0xEF,0xFB,0x2F,0xFA,0xCF,0xF9,0xFF,0xFB,0xFF,0xFF, /*自,2*/0xFF,0xFF,0xFF,0xFB,0x9F,0xFB,0xE3,0xFB,0xFF,0xC3,0x9F,0xD8,0xE1,0xDB,0xEF,0xDB,0xB7,0xDD,0x9B,0xDD,0xA3,0xEE,0x7F,0xEF,0xBF,0xEB,0xDF,0xF7,0xFF,0xFF,0xFF,0xFF, /*動,3*/0xFF,0xFF,0x7F,0xFF,0x6F,0xFF,0x6F,0xEF,0x77,0xF7,0x77,0xFB,0x73,0xFD,0x75,0xFE,0x36,0xFF,0x57,0xBF,0x77,0xBF,0x77,0xBF,0xF7,0x80,0xF7,0xFF,0xFF,0xFF,0xFF,0xFF, /*化,4*/0xFF,0xFF,0xFF,0xEF,0xEF,0xEF,0xDF,0xEF,0x1F,0xED,0xA3,0xED,0xB7,0xED,0xAF,0xED, 290xDF,0xED,0xDF,0xED,0xAF,0xEF,0x77,0xEF,0xF9,0xEB,0xFF,0xE7,0xFF,0xFF,0xFF,0xFF, /*劉,5*/0x7F,0xFF,0x7F,0xFC,0x0F,0xFF,0x3F,0xF8,0x47,0xFB,0x2F,0xFA,0x6F,0xF9,0x1F,0xFE,0x7F,0xF9,0x07,0xCA,0x7F,0x9F,0xEB,0xFE,0xDB,0xF7,0x3D,0xEF,0xFF,0xE0,0xFF,0xFF, /*惠,6*/0x7F,0xF8,0x87,0xFB,0xFF,0xFD,0x0F,0xFD,0xFF,0xFD,0x07,0xFE,0xBF,0xFF,0xBF,0xF9,0xBB,0xFC,0xB7,0xFF,0x5F,0xFF,0xEF,0xFE,0xF7,0xFD,0xF8,0xF3,0xFF,0xC7,0xFF,0xFF, /*靈,7*/0xF7,0xF3,0x2F,0xF4,0xFB,0xF6,0xB7,0xF6,0xAF,0xEA,0x77,0xFB,0xB3,0xF9,0x5F,0xFF,0x7F,0xC0,0x01,0xFE,0x5F,0xFD,0x6F,0xFB,0x77,0xF7,0x79,0x8F,0x7F,0xFF,0xFF,0xFF, /*梁,8*/0xFF,0xFF,0xBF,0xFF,0x7F,0xFF,0xFF,0xFF,0x1F,0xF0,0x63,0xFF,0x7F,0xFF,0x6F,0xFF,0x5F,0xFF,0xBF,0xFF,0x5F,0xFF,0xE7,0xFC,0xF8,0xC1,0xFF,0xFF,0xFF,0xFF,0xFF,0xFF, / *文,9*/0xFF,0xFF,0xFF,0xF0,0x3B,0xFB,0xF7,0xFC,0x7F,0xF0,0x9F,0xF6,0x52,0xF4,0xD6,0xF6,0x5B,0xF4,0xDB,0xF6,0xD7,0xF2,0xE0,0xF7,0x1F,0xFE,0xFF,0x80,0xFF,0xFF,0xFF,0xFF, /*通,10*/0xFF,0xFD,0xEF,0xFD,0xEF,0xFE,0xEF,0xC6,0x77,0xF8,0x73,0xFD,0xB5,0xFD,0xD6,0xE1,0xF7,0xFD,0xF7,0xFD,0xF7,0xE1,0xF7,0xFD,0xF7,0xFD,0xFF,0xFD,0xFF,0xFD,0xFF,0xFF, /*作,13*/0xFF,0xFF,0x7F,0xFC,0x8F,0xFD,0xEF,0xFD,0xDF,0xFD,0x1F,0xFE,0xFF,0xFF,0xFF,0xFF,0xC7,0xC1,0xD9,0xDE,0xDD,0xEE,0xDD,0xE0,0xE3,0xFE,0xFF,0xFF,0xFF,0xFF,0xFF,0xFF, /*品,14*/0xFF,0xFE,0xFF,0xFE,0xFF,0xFE,0x7F,0xFF,0x67,0xE1,0x69,0xF6,0xAF,0xFB,0xED,0xFE,0xEB,0xFE,0xF7,0xFE,0x6B,0xFD,0x7D,0xFB,0xBE,0xE7,0xDF,0x8F,0xFF,0xFF,0xFF,0xFF, /*歡,17*/0xFF,0xFF,0xFF,0xFE,0x7B,0xFE,0x97,0
