Applicable Boards:
NanoPi NEO
NanoPi NEO Air
NanoPi NEO2
NanoPi NEO Plus2

Install Software

To make a master device work with a NanoHat OLED you need to install a customized ROM on that master device. FriendlyElec names these image files with "xxx-OLED-xxx". For the NanoPi NEO/Air/NEO2 you need to download and run an image whose name is like "xxx-OLED-xxx". There are some code samples for NanoHat OLED. You can get these samples by running the following commands under Ubuntu core:

git clone
cd NanoHatOLED
sudo -H ./

Run Code Samples

After the code samples are installed they will automatically run on system reboot and display date and time
Here are the definitions of the NanoHat OLED's three user buttons:
K1 -> Show date & time;
K2 -> Show master device's system status: IP address, CPU usage, RAM, CPU temperature and etc;
K3 -> Shutdown. After this button is pressed system will not be shut down immediately but will pop up a Yes/No dialog. Pressing K1 switches between Yes and No, and pressing K2 is to confirm the selection.
