device.h

/*
 * device.h
 *
 * Code relating to the "device" ie the eink "PAPER" itself (as opposed the PCB module which drives it)
 *
 * This stripped down to JUST the -llgpio implementation for the Raspberry PI (4 & 5)
 *
 * The vast majority of this code comes from EPD_1in54b_V2.h in the waveshare
 * project @ https://github.com/waveshareteam/e-Paper
 * 
 * Modded to follow normal C convections (variables lowercase, MACROs and constants upper case, types capitalised)
 * 
 * 
 * Their PD statement reproduced below
