This library contains a driver for the [4.2 Inch E-Paper Moduel](https://www.waveshare.com/wiki/4.2inch_e-Paper_Module) from Waveshare. |
|
|
|
|
|
|
|
|
|
IN WORK! Drivers for various EPDs from Waveshare. |
|
|
|
|
Support for more (especially the smaller and faster ones) should follow after the library around the 4.2" EInk is stable and tested enough. |

## 4.2 Inch E-Ink |

|
|
|
|
|
|
Out of the Box the original driver from Waveshare supported only full updates. |
|
|
|
|
|
|
|
|
|
Currently only support for the 4.2 Black/White one |
|
|
|
|
|
|
|
|
|
Be careful with the partial updates! |
|
|
|
|
It was only tested in a mBED implementation, the rust one wasn't tested enough yet!!! |

### With a Buffer |
|
|
|
|
|
|
|
|
|
- Chars, Strings and filled circles are still missing |
|
|
|
|
- maybe work with traits here for line_drawing and so on? |

### Without a Buffer |
|
|

Maybe add support for Non-Buffer drawing from the https://crates.io/crates/embedded-graphics Crate later on. |
