【文章內(nèi)容簡介】 F8,0x08,0x0F,0x01, 0x41,0x41,0x41,0x4F,0x51,0x61,0x41,0x01,0x00,下半部取模為：0x01,0xC2,0x44,0x28,0x30,0xCE,0x04,0x00,0x02,0x01,0xFE,0x00,0x00,0x00,0x00,0x00,在實際程序中要用到字符表通過循環(huán)函數(shù)來實現(xiàn)漢字的顯示。例：unsigned char a[]={0x08,0x08,0x0F,0xF8,0x08,0x0F,0x01, 0x41,0x41,0x41,0x4F,0x51,0x61,0x41,0x01,0x00}。 unsigned char b[]={0x01,0xC2,0x44,0x28,0x30,0xCE,0x04,0x00,0x02,0x01,0xFE,0x00,0x00,0x00,0x00,0x00,} for(i=0。i16。i++) { PORTA=a[i]。 PORTB=b[i]。 delay(100)。 }下面我們來設(shè)計一個漢字滾動顯示的程序。顯示效果如圖53所示。漢字向左循環(huán)滾動。圖53 漢字移位圖程序如下：unsigned char a[]={0x08,0x08,0x0F,0xF8,0x08,0x0F,0x01, 0x41,0x41,0x41,0x4F,0x51,0x61,0x41,0x01,0x00}。unsigned char b[]={0x01,0xC2,0x44,0x28,0x30,0xCE,0x04,0x00,0x02,0x01,0xFE,0x00,0x00,0x00,0x00,0x00,} void display() { unsigned int i,j。 for(j=0。j16。j++) { PORTA=a[(i+j)%16]。 PORTB=b[(i+j)%16]。 } i++。 }該程序可以實現(xiàn)沒運行一次后顯示表依次左移一位。字符的取模用兩種方式，通過Excel手動計算和用專業(yè)的軟件實現(xiàn)。上面的例子就是通過計算得出的，但字符較多時最好采用軟件取模。下面我們來介紹一個軟件《字符取?！?。如圖54所示。圖54 取模軟件旋轉(zhuǎn)LED顯示屏的顯示內(nèi)容規(guī)劃如下：電機啟動后，循環(huán)顯示全亮、花形花形動態(tài)文字（鞍山師范物理科學(xué)學(xué)院）、花形靜態(tài)文字（09級畢業(yè)生作品展示?。?、花形4。旋轉(zhuǎn)LED顯示屏采用掃描方式進行顯示,其實現(xiàn)原理是通過控制不同時間段內(nèi)讓不同批次的LED輪流點亮,根據(jù)人眼的視覺暫留特性,當(dāng)掃描幀頻達到24Hz以上時,人眼便感覺不到掃描過程,而是一幅穩(wěn)定的圖像。但是在運用相機拍照過程中，相機的靈敏度比人眼球高很多，因此拍到的不是一幅穩(wěn)定的完整的圖像，而是一個片段。圖55 顯示花形1圖56 顯示花形2圖57 顯示文字（鞍山師范物理科學(xué)學(xué)院）圖58 顯示花形3圖59 顯示文字（09級畢業(yè)生作品展示）圖510 顯示花形4圖511 顯示全亮單片機的設(shè)計中，程序就等于它的靈魂，如果沒有程序的支撐，再好的設(shè)計結(jié)構(gòu)都只是一個支架，不具有任何意義。所以我們設(shè)計的重點內(nèi)容就是編寫我們所需要的程序文件，需要大量的時間和精力來完成這項工作。 程序源文件include //加載頭文件includedefine uint unsigned int //宏定義uint為unsigned int 類型define uchar unsigned char //宏定義uchar為unsigned char 類型pragma interrupt_handler int0_aaa:2 //外部中斷int0void delay(uint ms) //延時子函數(shù){ uint i,j。 for(i=0。ims。i++) { for(j=0。j5。j++)。 } }uchar num_a[]={ //字符上半部分/* 文字: 鞍 */0x20,0x23,0xFA,0x2F,0xFA,0x27,0x19,0x11,0x11,0x97,0x71,0x11,0x11,0x15,0x19,0x00,/* 文字: 山 */0x00,0x00,0x0F,0x00,0x00,0x00,0x00,0xFF,0x00,0x00,0x00,0x00,0x0F,0x00,0x00,0x00,/* 文字: 師 */0x00,0x3F,0x00,0x00,0xFF,0x00,0x40,0x47,0x44,0x44,0x7F,0x44,0x44,0x47,0x40,0x00,/* 文字: 范 */0x20,0x22,0x21,0x28,0x26,0xF0,0x20,0x27,0x24,0xF4,0x24,0x24,0x27,0x20,0x20,0x00,/* 文字: */0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,/* 文字: 物 */0x02,0x3C,0x08,0xFF,0x08,0x08,0x04,0x08,0xF1,0x1E,0x10,0x1F,0x10,0x1F,0x00,0x00,/* 文字: 理 */0x20,0x21,0x21,0x3F,0x21,0x21,0x00,0x7F,0x49,0x49,0x7F,0x49,0x49,0x7F,0x00,0x00,/* 文字: 科 */0x24,0x24,0x25,0x7F,0xC5,0x44,0x00,0x44,0x33,0x00,0x00,0xFF,0x00,0x00,0x00,0x00,/* 文字: 學(xué) */0x02,0x0C,0x88,0x69,0x09,0x09,0x89,0x69,0x09,0x09,0x19,0x28,0xC8,0x0A,0x0C,0x00,/* 文字: 學(xué) */0x02,0x0C,0x88,0x69,0x09,0x09,0x89,0x69,0x09,0x09,0x19,0x28,0xC8,0x0A,0x0C,0x00,/* 文字: 院 */0x00,0x7F,0x44,0x5A,0x61,0x08,0x30,0x24,0x24,0xA4,0x64,0x24,0x24,0x28,0x30,0x00,/* 文字: */0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,/* 文字: */0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,/* 文字: */0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00, }。/*字符下半部*/uchar num_b[]={/* 文字: 鞍 */0x10,0xD0,0x50,0xFF,0x50,0xD0,0x01,0x21,0xD2,0x14,0x08,0x14,0xE2,0x01,0x00,0x00,/* 文字: 山 */0x00,0x00,0xFC,0x04,0x04,0x04,0x04,0xFC,0x04,0x04,0x04,0x04,0xFE,0x00,0x00,0x00,/* 文字: 師 */0x00,0xE1,0x02,0x0C,0xF0,0x00,0x00,0xF8,0x00,0x00,0xFF,0x10,0x08,0xF0,0x00,0x00,/* 文字: 范 */0x00,0x10,0x90,0x1E,0x20,0xC0,0x00,0xFC,0x02,0x02,0x42,0x22,0xC2,0x02,0x1E,0x00,/* 文字: */0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,/* 文字: 物 */0x40,0x60,0x40,0xFF,0x80,0x80,0x20,0x42,0x84,0x18,0x62,0x81,0x02,0xFC,0x00,0x00,/* 文字: 理 */0x04,0x06,0x04,0xF8,0x08,0x08,0x02,0x22,0x22,0x22,0xFE,0x22,0x22,0x22,0x02,0x00,/* 文字: 科 */0x10,0x60,0x80,0xFF,0x00,0x80,0x20,0x20,0x20,0x20,0x20,0xFF,0x40,0x40,0x40,0x00,/* 文字: 學(xué) */0x20,0x20,0x20,0x20,0x20,0x22,0x21,0x7E,0x60,0xA0,0x20,0x20,0x20,0x20,0x20,0x00,/* 文字: 學(xué) */0x20,0x20,0x20,0x20,0x20,0x22,0x21,0x7E,0x
