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.

Supported displays

Display Colors Supported Partial update[^1] Fast refresh[^2] Tested
WeAct 1.54 inch 200x200 B/W Black, White
WeAct 2.13 inch 122x250 B/W Black, White
WeAct 2.13 inch 122x250 B/W/R Black, White, Red
WeAct 2.9 inch 128x296 B/W Black, White
WeAct 2.9 inch 128x296 B/W/R Black, White, Red
WeAct 4.2 inch 400x300 B/W Black, White

[^1]: Allows updating part of the screen buffer to save IO time and potentially memory.

[^2]: Refresh the screen without flickering the screen a few times.

Examples

See the examples folder for complete usage examples.

Features

  • blocking: Replaces the API with a blocking version. This disables the async API so you cannot use both in the same project.
  • graphics: Enables embedded-graphics support. Enabled by default.
