在這里放一份, 方便測試屏幕的時候用, 這樣不需要臨時找
pin腳定義

代碼看附件, 項目只有一個main.c, 需要修改的是這部分, 因為使用GPIO模擬的SPI, 所以基本上可以換成任意IO口

sbit CS=P3^5;
sbit RESET=P3^7;
sbit CD=P3^6;
sbit SCL=P3^2;
sbit SDA=P3^4;

不是, 老王店里的, 是ST7567, 今天看好像又上架了

不過這兩者的驅(qū)動基本上是一樣的, 除了兩點: 睡眠模式的命令不同, 還有ST7567允許寫內(nèi)存自動換頁而ST7565不允許, 其它完全一樣.

老王的ST7567我也寫了驅(qū)動了,

兩個圖片, 一個圖片里顯示的是兩行文字, 64-C0G! WGM-128, 另一個應(yīng)該是插入卡之類的.

你這樣點亮了基本上就沒什么大問題了, 調(diào)調(diào)參數(shù)很快就能正常用了.

c語言我玩不轉(zhuǎn) 打算把程序精簡一下只保留最基本的顯示然后反編譯成匯編參考19264的匯編程序用
