Hardware connection (OLED => Raspberry Pi)

  • VCC -> 3.3
  • GND -> GND
  • DIN -> MOSI
  • CLK -> SCLK
  • CS -> 24 (Physical, BCM: CE0, 8)
  • D/C -> 22 (Physical, BCM: 25)
  • RES -> 11 (Physical, BCM: 17)
  • BUSY -> 18 (Physical, BCM: 24)

How to use

  1. Make sure that Pillow (friendly fork of the Python Image Library) is running well on your Raspberry Pi.
    pip install --upgrade Pillow
  2. Change the current directory to epaper-type/raspberrypi/python (epaper-type is the type of your e-paper display)
    cd epaper-type/raspberrypi/python
  3. run the demo with:    
    python main.py

Supported models

1.54"/1.54" B/2.13"/2.13" B/2.7"/2.7" B/2.9"/2.9" B/4.2"/4.2 B/7.5"/ 7.5" B
