il3820-spin

This is a P8X32A/Propeller driver object for the IL3820 electrophoretic (E-Ink, E-Paper) display controller

IMPORTANT: This software is meant to be used with the spin-standard-library (P8X32A) or p2-spin-standard-library (P2X8C4M64P). Please install the applicable library first before attempting to use this code, otherwise you will be missing several files required to build the project.
