luma.core

luma.core is a component library providing a Pillow-compatible drawing canvas for Python 3, and other functionality to support drawing primitives and text-rendering capabilities for small displays on the Raspberry Pi and other single board computers:

• scrolling/panning capability,
• terminal-style printing,
• state management,
• color/greyscale (where supported),
• dithering to monochrome,
• sprite animation,
• flexible framebuffering (depending on device capabilities)

Documentation

API documentation can be found at https://luma-core.readthedocs.io/en/latest/

Drivers

Device drivers extend luma.core to provide the correct initialization sequences for specific physical display devices/chipsets.

There are several drivers for different classes of device available:

• luma.oled
• luma.lcd
• luma.led_matrix
• luma.emulator

Emulators

There are emulators that run in real-time (with pygame) and others that can take screenshots, or assemble animated GIFs, as per the examples below. Source code for these are available in the examples directory of the luma.examples repository.
