Originally forked from the waveshare/e-Paper repository.

This repository has been reduced to work with the Waveshare 5.83'' e-Paper display on a Raspberry Pi. Support for other displays has been removed completely. Moreover it's meant to support only the C(++) programming language using the bcm2835 library instaed of Wiring Pi.
