Raspberry Pico W with Waveshare 7.5 in epaper (black/white)

Hardware Setup

• https://www.waveshare.com/wiki/Pico-ePaper-7.5

Micropython

• https://micropython.org/download/rp2-pico/ (alternatively use Thonny)

Image Prep (Gimp)

• Resize Images to 800x480
• Image -> Mode -> Indexed...
• Use black and white (1-bit) palette
• Color dithering - Floyd-Steinberg (normal)
• Save as pbm

Steps to use

• Add images to an "input" folder
• Run img_process.py for image prep (can skip doing this in GIMP)
• Run img_generate.py (breaks image into small chunks to avoid memory allocation errors)
• Upload contents of the "bmp" folder to pico
• Run disp.py on pico

Features coming soon (aka in 3 months hopefully)

• Google Drive support
• Image Loop
• Self-sustained power source?
