§weact-studio-epd

Unofficial Rust driver for WeAct Studio e-paper displays.

The driver exposes both write access to the screen frame buffers and higher-level embedded-graphics support.

By default this driver uses async. If you prefer to use a blocking API instead you can enable the blocking feature.
