0.91 OLED (English)

Description

This tiny OLED display module is specially design for raspberry Pi,the module use less of raspberry pi's pins and make little spacing occupying,The micro control chip ssd1306 which communicate with Raapberry Pi via I2C interface ,and whose work voltage is 3.3V. So that this OLED can be used on any Raspberry Pi board

If it's the first time for you to use Raspberry Pi, please make sure the I2C interface is enabled. This page will show you how to enable the I2C interface. http://www.52pi.net/forum.php?mod=viewthread&tid=1363&highlight=rtc

Download OLED'sssd1306 driver,If you are done download the device driver,extract them copy and past to /home/Pi folder

Type sudo apt-get install build-essential git-core libi2c-dev i2c-tools lm-sensors to install necessary component

If the steps above are done,next typesudo vim.tiny /etc/modulesto modify modules file just like the following

i2c-bcm2708
i2c-dev

sudo make安装驱动程序

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

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