Leigh Brooks / EaEpaper_EM027BS013

Driver to control the EM027BS013 board from Embedded Artists

Dependencies:   EM027BS013

EM027BS013 Simple Driver

This library provides an easy way to write data to the EM027BS013 display, by providing interfaces to common C functions and methods. The library was originally written by Peter Drescher, who created the "EaEpaper" library for the EM027AS012 display (available here, but adapted to use the newer display type and driver (available here), as the existing display is now discontinued.

Big thanks go to the team from Pervasive Displays and Electronic Artists for producing such a nice display, and to Peter for providing the initial interface used in this driver.
