This is an example for our Monochrome OLEDs based on SSD1306 drivers
Pick one up today in the adafruit shop!
------> http://www.adafruit.com/category/63_98
This example is for a 128x64 size display using I2C to communicate
3 pins are required to interface (2 I2C and one reset)

} SSD1306 chip 果塊, 唔係 12864 嗎?家陣變左 2864?28 x 64 pixel?
樓主會唔會懶左 D, 連有乜問題都唔講, 只係 copy 段 code 再貼張相出黎, geek-workshop 幾時變左 猜謎區? OLED啊？接线简单 你遇到什么问题了，请具体说明。提问时请说明你的接线，遇到的问题，采取解决的步骤等，越详细得到的帮助越具体。 这个模块不是有很好的例子吗。有什么问题？ 老胖熊 发表于 2015-3-26 09:58 static/image/common/back.gif
这个模块不是有很好的例子吗。有什么问题？
我用的Arduino mega 2560的板子，接线老是不显示
SCL-> SCL
SDA-> SDA
RST-> D4
DC-> GND
3.3-> 3.3v
g-> GND
这是我的接线图 gongsixingxi 发表于 2015-3-26 11:14 static/image/common/back.gif

上面这个例程是Arduino uno的，那个接线是A4,A5,这些接线我都试了，是不是我接线那里有问题哦 gongsixingxi 发表于 2015-3-26 11:16 static/image/common/back.gif

MEGA2560的SDA,SCL不在A4,A5
去看一下pinout吧!! Super169 发表于 2015-3-25 14:30 static/image/common/back.gif

请问这个是什么模块来的，有无具体的代码例子，这个OLED好似我最近都想买个 gongsixingxi 发表于 2015-3-26 11:14 static/image/common/back.gif

问问题的时候，应该把你的问题写清楚，这样看起来稍微明白你想问什么了。我用过类似的模块，不过我买的那个模块字印错了，把我的接线方式告诉你，供参考。
OLED 软件SPI：
D/CDC 11
RSTRESET13
SDAMOSI 9
SCLCLK 10
VCC +5V
GND GND
CS 12
如果使用硬件SPI，按以下方式连接和定义
D/CDC 9
CS 10
RSTRESET8
SDAMOSI 11 mini pro 已经定义，不需要再定义，这里是接线提示。
MISO 12 mini pro 已经定义，不需要再定义，这里是接线提示。
SCLCLK 13 mini pro 已经定义，不需要再定义，这里是接线提示。
中间那一列你不必介意，我用的是mini pro，你的板子端口定义要查一下接口图，坛子里有，自己找一下吧。
