今天終于把點(diǎn)陣液晶顯示出漢字了,自學(xué)太吃力,點(diǎn)陣遭遇經(jīng)歷差點(diǎn)把我打擊的放棄了,這些時(shí)間心里真是很矛盾,當(dāng)我看到單片機(jī)真是既愛又怕,就;連這個(gè)簡(jiǎn)單的液晶驅(qū)動(dòng)在看了很多資料,無數(shù)次改寫程序都是失敗結(jié)局.每次新的思路閃現(xiàn)總讓我興奮,但結(jié)果都很失望...........
呵呵,今天的小進(jìn)步做為給自己鼓勵(lì), 希望自己如蝸牛般急馳學(xué)習(xí)單片機(jī)!堅(jiān)持.....堅(jiān)持.....

請(qǐng)問除了把12864連到單片機(jī)上，還使用了什么芯片輔助嗎？我用的是開發(fā)板但是編寫的程序也是不帶字庫(kù)的，結(jié)果固有端口就不能用了
