RasPi Video to OLED

Without soldering, wiring or any specific hardware knowledge, you can easyly click this project together and create a viewfinder for your PIcamera.

I marked this project intermediate rather than easy, simply because installation of the libraries might cause slightly issues depending on your starting point of your Raspbian OS. From a clean installation, such as the one I described here: https://www.hackster.io/gotfredsen/raspberry-pi-weather-station-8562ad, the below should work without problems.

Step 1: Install libraries and other software

• Activate I2C and the PiCamera using sudo raspi-config

• Follow instructions from here: https://luma-oled.readthedocs.io/en/latest/install.html and https://github.com/rm-hull/luma.examples. The short version you find below ;-)

sudo apt install vim git
sudo apt install python-dev python-pip libfreetype6-dev libjpeg-dev build-essential
sudo -H pip install --upgrade luma.oled
sudo -H pip install picamera 
sudo apt install libsdl-dev libportmidi-dev libsdl-ttf2.0-dev libsdl-mixer1.2-dev libsdl-image1.2-dev
sudo -H pip install --upgrade pip setuptools
git clone https://github.com/rm-hull/luma.examples.git
cd luma.examples
sudo -H pip install -e .
cd examples

Step 2: Modify the example

• Using vim or another editor, edit the file picamera_video.py .

• Find the line cameraResolution = (640, 480) and change it to cameraResolution = (128, 64)

• Find the line cameraFrameRate = 8 and change it to cameraFrameRate = 4

• Run the program: python picamera_video.py

• If you cant't stop the program with CTRL+c, try CTRL+\

Enjoy!
