-# eink-waveshare-rs
+This library contains a driver for the [4.2 Inch E-Paper Module](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.
 
-Currently only support for the 4.2 Black/White one
+## (Supported) Devices
 
-Be careful with the partial updates!
-It was only tested in a mBED implementation, the rust one wasn't tested enough yet!!!

+### 4.2 Inch E-Ink Black/White
+
+Out of the Box the original driver from Waveshare only supports full updates. 
+
+- [1]: Be careful with the quick refresh updates: <br>
+It's possible with this driver but might lead to ghosting / burn-in effects therefore it's hidden behind a feature.

 ## TODO's
 
-- [ ] add more example (e.g. for f3)
+- [ ] add more examples (e.g. for f3)
 - [ ] improve the partial drawing/check the timings/timing improvements/....
 - [ ] for later: add support for the smaller waveshare epds
-- [ ] License: Stay with ISC (=MIT) or go to Apache+MIT Dual Version as used in many other projects?

 Support for bigger sized/independent Fonts is in work.
 
+## Examples
 
-### 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.
+There is an example for Raspberry Pi in the example folder.
