概述

IM140714003 3.JPG

市面上很少能找到为树莓派量身定制的OLED屏幕，/在很多应用项目中，我们仅需要显示非常简单的一些信息，比如系统状态、IP等信息，/或者对便携性有较高需求，这时候用HDMI去接一个大屏幕明显不合适，一个小巧的OLED屏幕刚好能满足这种需求。

OLED Add-on是为树莓派量身定制的，板载一块0.96" 128*64 OLED屏幕，控制芯片为SSD1306，每一个像素点都可以通过SSD1306独立控制点亮或者关闭。

我们不仅仅只是提供一块可以方便的插在树莓派上面的板子，还为其配套提供了SDK，移植了Arduino上的驱动程序。安装完SDK后，就可以像在Arduino平台底下一样，非常轻松的驱动这块板子。

Instruction

  • Plug OLED add-on into Raspberry Pi and power it
  • modify the file /etc/modprobe.d/raspi-balcklist.conf
modified codes as below
blacklist spi-bcm2708
blacklist i2c-bcm2708
  • modify /etc/modules
add a line in the end as below:
i2c-dev
  • reboot
  • Download the SDK from this link: https://github.com/iteadsw/SDK and then install it
  • Enter into the directory libraries/itead_SSD1306/examples/oled_Animation_Sample/, then compile and run this file oled_Animation_Sample.ino
Command as below to compile oled_Animation_Sample.ino
$ iteadcompile OLED oled_Animation_Sample.ino
Command to run this program
$ sudo ./OLED
  • When the compilation is done, you can see a little man dancing on OLED.
