----
==How to use==
First of all, you should turn on I2C function on your Pi by editing /boot/config.txt file.<br>
<code>sudo vim.tiny /boot/config.txt </code><br>
make sure you can find this parameter:<br>
<code>dtparam=i2c_arm=on</code><br>
And don't forget to reboot your Pi.<br>
* Login your Pi and download driver:<br>
<code>git clone -b ArduiPi_OLED  https://github.com/yoyojacky/libssd1306</code>
*Compile it and run:<br>
<code>cd  libssd1306/ </code><br>
<code>sudo make </code><br>
<code>cd  example/</code><br>
<code>sudo  make</code><br>
<code>sudo ./oled_demo -o 2 </code><br>
if you need help, you can just use this command:<br>
<code>sudo ./oled_demo -h </code><br>

===FAQ===
*Question:  why does it  not show anything that I've tried as your instruction？ <br>
**Answer:    Please make sure you have already open your i2c function and you can use this command to detect whether it has been turned on already.<br>
**<code> i2cdetect -y 1 </code>

==Application Senario==
* There is a maker made a funny thing called "mobile pi" with this 0.91 Inch OLED Module, you can check it by accessing following link:
