上排屏幕和下排屏幕重復(fù)我就不說了。字體難看我就不說了。這個(gè)液晶真是煩人啊，引腳定義都是反的……唉………先放個(gè)程序。發(fā)現(xiàn)如何setpage，set到0、1沒問題，2、3就顯示不出了。真不知道是我的錯(cuò)還是液晶的錯(cuò)。無論是左還是右都一樣。
這個(gè)是模擬8080時(shí)序的，比6800稍微簡(jiǎn)單。在STC89C52 @ 11.0592下通過。
這塊液晶最后還讓我用串口進(jìn)行調(diào)試了，暈。
這個(gè)液晶真是……哎……
好吧。附上真正的引腳定義（淘寶賣家那個(gè)害死我了）：
GND VCC Vo A0 CS1 CS2 CLK(2KHZ的時(shí)鐘輸入） RD WR DB0～DB7 RST LED+ LED-
注意在5V系統(tǒng)上用的時(shí)候LED+需要串個(gè)20~47R的電阻。要不然會(huì)嚴(yán)重發(fā)熱。
CLK不能直接接單片機(jī)的ALE腳，否則不會(huì)有任何顯示（那個(gè)是2M）
RESET無法拉高所以6800時(shí)序沒法用。只能用8080時(shí)序。
貌似上下兩排顯示公用一個(gè)VRAM。我現(xiàn)在還沒找到解決顯示重復(fù)的辦法……
順帶提醒一下，這個(gè)液晶的視角很窄，所以更加建議使用3塊錢紫晶的。更便宜更好用，資料也比較齊全。
