epdfuse

epdfuse is a library for interacting with the PaPiRus epaper display using golang and the repaper epd fuse native library.

This library provides the ability to write arbitrary text and images to the display as well as clear the display.

It leverages the goxbm project to convert images to the XBM format used by EPD Fuse.

Install and setup

Install Go

Go runs easily on the Raspberry PI. This stackexchange answer provides a quick overview: http://raspberrypi.stackexchange.com/a/46828/167.

If cross compiling on a different computer, use these settings GOARM=5 GOOS=linux GOARCH=arm.

GOARM=5 GOOS=linux GOARCH=arm go build

Install Fuse Driver

The repaper fuse driver is required to use this golang library.

# Install fuse driver
