4、了解點陣屏顯示字符的原理與過程。 </p><p>　　二、綜合實踐理論基礎和核心內(nèi)容</p><p>　　1. 給點陣24HZ以上的列掃描信號，同時給行不同的字符編碼，從而讓點陣顯示不同的花色和字符 </p><p>　　2. 用兩個三八譯碼器對四位二進制數(shù)進行譯碼從而實現(xiàn)16位二進制數(shù)的循環(huán)移位，以此作為16位列掃描信號。</p><p&g

5、t;　　3. 點陣控制器的rst時鐘輸入用來控制行依次亮滅的速度，因此其頻率必須小于24HZ以保證人眼能夠區(qū)分。</p><p>　　4. din用來控制點陣顯示不同的字符和花色，應當在實驗開始前就接高電平或低電平,當din給低電平時，點陣的行從上往下依次點亮后又從下往上依次熄滅；當din給高電平時，點陣屏上循環(huán)顯示“中”“國”“人”三個字。</p><p>　　三、綜合實踐具體內(nèi)容
