eink-wave 0.1.0

Modernized Waveshare e-Paper library using python-periphery and uv

E-Paper Display Library

A modernized version of the Waveshare e-Paper library that uses python-periphery for hardware interface and uv for package management.

What's Different

• Uses python-periphery instead of direct GPIO/SPI access
• Uses uv for fast Python package management
• Updated to modern Python practices
• Better error handling and logging
• Simplified project structure
• Lazy imports to avoid GPIO initialization on development machines

Quick Start

1. Install dependencies:

uv sync

2. Run the simple demo:

python start.py

Usage

Import specific display modules as needed:

from waveshare_epd.epd4in2_V2 import EPD

# Initialize display
epd = EPD()
epd.init()
epd.Clear()

# Create and display image
from PIL import Image, ImageDraw
image = Image.new('1', (epd.width, epd.height), 255)
draw = ImageDraw.Draw(image)
draw.text((10, 10), 'Hello World!', fill=0)
epd.display(epd.getbuffer(image))

Supported Displays

Works with various e-paper displays: 1.54", 2.13", 2.7", 2.9", 4.2", 5.83", and 7.5" models.

Demo Features

The demo script showcases:

• Text and graphics rendering
• 4-gray mode display
• Partial update animations
• System information display

Requirements

• Python 3.8+
• uv package manager
• python-periphery
• PIL (Pillow)
• Raspberry Pi or Jetson Nano (for hardware)
