26一、課題要求1.1問題描述：本實(shí)驗(yàn)主要完成漢字字符在LED上的顯示，16*16掃描LED點(diǎn)陣的工作原理與8位掃描數(shù)碼管類似，只是顯示的方式與結(jié)果不一樣而已。下面就本實(shí)驗(yàn)系統(tǒng)的16*16點(diǎn)陣的工件原理做一些簡單的說明。16*16點(diǎn)陣由此256個(gè)LED通過排列組合而形成16行*16列的一個(gè)矩陣式的LED陣列，俗稱16*16點(diǎn)陣。單個(gè)的LED的電路如下圖11-1所示：Rn———Cn圖11-1單個(gè)LED電路圖由上圖可知，對(duì)于單個(gè)LED的電路圖當(dāng)Rn輸入一個(gè)高電平，同時(shí)Cn輸入一個(gè)低電平時(shí)，電路形成一個(gè)回路，LED發(fā)光。也就是LED點(diǎn)陣對(duì)應(yīng)的這個(gè)點(diǎn)被點(diǎn)亮。16*16點(diǎn)陣也就是由16行和16列的LED組成，其中每一行的所有16個(gè)LED的Rn端并聯(lián)在一起，每一列的所有16個(gè)LED的Cn端并聯(lián)在一起。通過給Rn輸入一個(gè)高電平，也就相當(dāng)于給這一列所有LED輸入了一個(gè)高電平，這時(shí)只要某個(gè)LED的Cn端輸入一個(gè)低電平時(shí)，對(duì)應(yīng)的LED就會(huì)被點(diǎn)亮。具體的電路如下圖11-2所示：圖11-216*16點(diǎn)陣電路原理圖在點(diǎn)陣上顯示一字符是根據(jù)其字符在點(diǎn)陣上的顯示的點(diǎn)的亮滅來表示的，如下圖11-3所示：圖11-3字符在點(diǎn)陣上的顯示在上圖中，顯示的是一個(gè)“漢”字，只要將被“漢”字所覆蓋的區(qū)域的點(diǎn)點(diǎn)亮，則在點(diǎn)陣中就會(huì)顯示一個(gè)“漢”字。根據(jù)前面我們所介紹的點(diǎn)陣顯示的原理，當(dāng)我們選中第一列后，根據(jù)要顯示漢字的第一列中所需要被點(diǎn)亮的點(diǎn)對(duì)應(yīng)的Rn置為高電平，則在第一列中需要被點(diǎn)亮的點(diǎn)就會(huì)被點(diǎn)亮。依此類推，顯示第二列、第三列……第N列中需要被點(diǎn)亮的點(diǎn)。然后根據(jù)人眼的視覺原理，將每一列顯示的點(diǎn)的間隔時(shí)間設(shè)為一定的值，那么我們就會(huì)感覺顯示一個(gè)完整的不閃爍的漢字。同時(shí)也可以按照這個(gè)原理來顯示其它的漢字。下圖11-4是一個(gè)漢字顯示所需要的時(shí)序圖：章統(tǒng)時(shí)鐘
