- SPI or I2C enabled
-
sudo raspi-config-> interfacing options -> [enable SPI or I2C]
-
Wiring
- Wire up OLED display according to the SPI or I2C documentation for the Waveshare display.
- Power LED (red) is wired via a resistor to 5V.
- System LED (green) is wired to BCM PIN 26.
- Activity LED (orange) is wired to BCM PIN 6.
Requires these modules:
- psutil
- Paho MQTT
- PILLOW
Installation this application
pip install psutil pip install paho-mqtt sudo apt-get install libjpeg-dev # needed by pillow pip install pillow pip install spidev sudo apt-get install python-smbus i2c-tools cd /home/pi mkdir -p projects/displayApp cd /home/pi/projects wget https://github.com/SupremeC/RPI_InfoScreen/archive/master.zip unzip master.zip mv RPI_InfoScreen-master/* ./displayApp rm -rf RPI_InfoScreen-master rm master.zip
How to use
