【文章內(nèi)容簡介】 碼 漢字的機(jī)內(nèi)碼是指在計(jì)算機(jī)中表示一個漢字的編碼。機(jī)內(nèi)碼與區(qū)位碼稍有區(qū)別。如上所述，漢字區(qū)位 碼的區(qū)碼和位碼的取值均在 1~94 之間，如直接用區(qū)位碼作為機(jī)內(nèi)碼，就會與基本 ASCII 碼混淆。為了避免機(jī)內(nèi)碼與基本 ASCII 碼的沖突，需要避開基本 ASCII 碼中的控制碼 (00H~1FH)，還需與基本 ASCII 碼中的字符相區(qū)別。為了實(shí)現(xiàn)這兩點(diǎn)，可以先在區(qū)碼和位碼分別加上 20H，在此基礎(chǔ)上再加80H(此處“ H”表示前兩位數(shù)字為十六進(jìn)制數(shù) )。 我們可以通過這個軟件將我們所要的使用的“機(jī)械電子”這四個字的代碼給得出來，方便我們進(jìn)行 C語言編程。 程序編寫 以下是 8*8點(diǎn)陣 LED字符顯示器完整的 C程序清單： include define char unsigned char define int unsigned int /***********機(jī)械電子 代碼 ********/ char
