U6143_ssd1306

This fork contains alternative display modes.

C - the original files with a fix to the IP address to use eth0.

C_HostName_IP - updated to display the host name on top and added a 4th display in the loop containing the IP address.

C_StaticHostName_IP - updated to only display the hostname and IP address.

Replace C_HostName_IP in the commands if you plan on using a different display mode.

Preparation

sudo raspi-config

Go to Interface Options and Enable i2c

Clone U6143_ssd1306 library

cd ~/scripts
git clone https://github.com/robertalexa/U6143_ssd1306.git

Rasbian Lite

• If you are running Lite then you will need to manually install wiringpi or you will get an error while compiling
• Ignore this for other version of Raspbian - wiringpi is installed by default
• If you are running the beta x64 Raspian please read the instruction below about Incompatible WiringPi

sudo apt install wiringpi

Compile

cd ~/scripts/U6143_ssd1306/C_HostName_IP

sudo make clean && sudo make 

Run

sudo ./display

Incompatible WiringPI

If you get errors when you try to run sudo make then you will need to use a different version of WiringPi. The original project is not supported anymore.

sudo apt remove wiringpi
cd ~/scripts
git clone https://github.com/WiringPi/WiringPi
cd WiringPi
./build

Run the Compile and Run instructions again (above). It should all work now.

PS: I have no affiliation with the author of the WiringPi fork used in these instructions. I also take no responsibility for the code in that repo, should you have any concerns over what it does feel free to look at the repo before using it.

Recommended - Add automatic systemd service

• replace C_HostName_IP folder with whatever version you are using

sudo systemctl link /home/pi/scripts/U6143_ssd1306/C_HostName_IP/ssd1306.service
sudo systemctl enable ssd1306.service
sudo systemctl start ssd1306.service

This relies on you previously compiling. It will not recompile on its own.

Alternative - Add automatic script

• Open the rc.local file

sudo nano /etc/rc.local

• Add command to the rc.local file

cd /home/pi/scripts/U6143_ssd1306/C_HostName_IP
sudo make clean 
sudo make 
sudo ./display &

• reboot your system

This will recompile every time you boot. A bit wasteful.

For older 0.91 inch lcd without mcu

• For the older version lcd without mcu controller, you can use python demo
• Install the dependent library files

sudo pip3 install adafruit-circuitpython-ssd1306
sudo apt-get install python3-pip
sudo apt-get install python3-pil

• Test demo

cd /home/pi/scripts/U6143_ssd1306/python 
sudo python3 ssd1306_stats.py
