6 Manually Enable Support for NanoHat OLED for NanoPi NEO2 Black

FriendlyElec developed some demo programs for the NanoHat OLED for NanoPi NEO2 Black and these demo programs are contained in the NanoHatOLED's github. You can download and install these programs by running the following commands after you boot a NanoPi NEO2 Black:

git clone https://github.com/friendlyarm/NanoHatOLED.git
cd NanoHatOLED
sudo -H ./install.sh


Running the installation script will download necessary packages. You can set the download source to your preferred one to speed up the process. To change the download source run the following command:

wget http://112.124.9.243/aptsouce.sh
chmod 755 aptsouce.sh
sudo -H ./aptsouce.sh
sudo apt-get update

After the download steps are done run the "NanoHatOLED的 ./install.sh" script to install them.

7 Play with Demo Programs

The demo programs will be automatically run and show date, time and GUI after the OS loads.
The NanoHat OLED module has three keys and their functions are defined as follows:
K1 -> Shows date and time;
K2 -> Shows system status such as IP address, CPU usage, storage usage, CPU temperature and etc;
K3 -> Powers off the system. When this key is pressed the system will not immediately be turned off and instead it will pop up a confirmation window with a Yes and a No options. You can press the K2 key to select Yes or No;
