驱动OLED，没用第三方库，处女作
本帖最后由 butOn 于 2015-3-29 12:01 编辑第一次写驱动！


用MCU驱动OLED屏幕，
我没有用网上现成的程序，没有用第三方库，
而是自己根据厂家的数据手册，分析初始化流程以及串行通讯时序，写出一套自己的驱动。好像程序员都喜欢“重新制造轮子”。
由于Linux没有图形取模软件，所以只好自己一个格子一个格子弄点阵……那可是128*64=8192个啊！弄完还要一个一个转成16进制的，一共128*8=1024个……我的妈呀，死一大片脑细胞不说，打完手都要断啦……
所以只做了两个字母“b” “u”
自行脑补后面的t0n吧。

bitmap做完，显存总是没法写入，后来才发现二维数组定义后要立即赋值，还有串口不知道哪抽了，烧个程序平均要插个五六遍才有反应。
下面是源码：
/*
* OLED_Arduino.ino
*
* Created by Jack, March 28, 2015.
*
* FUNCTION: This is a driver program to display some pics or words（传说中的中式英语）
* on the OLED screen.
*
* OLED INFORMATION:
* 96` 128*64,
* driver chip: SSD1306,所罗门的驱动IC，这款IC还有用于驱动E-ink电子纸！
*
* INTERFACE: 4-wire SPI.

能够显示了，但是不是这样
对就是这样
代码我更新了，移植了字库，视频：http://v.youku.com/v_show/id_XOTI4NTExMTky.html?xhttp://v.youku.com/v_show/id_XOTI4NTExMTky.html?x butOn 发表于 2015-4-8 00:32 static/image/common/back.gif
