==如何使用==
#对于初次使用的用户请确保树莓派I2C接口已经打开,如何打I2C请参考 http://www.52pi.net/forum.php?mod=viewthread&tid=1363&highlight=rtc

#首先使用需下载安装0.91'OLED树莓派端驱动[[#tech1|ssd1306 driver]],下载完成后解压缩复制到树莓派用户目录下

#输入指令<code>sudo apt-get install build-essential git-core libi2c-dev i2c-tools lm-sensors</code>安装驱动屏幕所需要的组件

[[Image:Test1.png|center]]

#待安装完成后,进入/etc目录修改modules文件添加如下I2C硬件配置
<pre>i2c-bcm2708
i2c-dev</pre>

[[Image:Test4.png|center]]

#进入驱动文件目录下输入sudo make安装驱动程序

[[Image:Test5.png|center]]

#安装成功后打开example文件夹输入make指令编译示例程序，编译成功后发现，当前文件夹下已成功生成可执行文件ssd1306_demo

[[Image:Test6.png|center]]

#输入sudo ./ssd1306_demo执行可以看到0.91'OLED模块已经成功点亮
