# Waveshare E-Paper Display library for Pycom MicroPython

This library is based on the original Waveshare library for Raspberry Pi, available [here](https://www.waveshare.com/wiki/1.54inch_e-Paper_Module_(B)).

At the moment it supports 1.54" Waveshare two-color E-Paper Display only.

## Features

* Drawing lines (horizontal, vertical and between two arbitrary points)

* Drawing rectangles and circles, both regular and filled

* Drawing images from raw data (`list` or `bytes` object)

* Drawing images from BMP files (Windows-style 1-color bitmap)

* Adjusting screen orientation

* Power saving mode (~30uA)

## Usage

### Initializing

The e-paper display uses 6 data lines for communication:

    reset = Pin('P19')

    dc = Pin('P20')

    busy = Pin('P18')

    cs = Pin('P4')

    clk = Pin('P21')

    mosi = Pin('P22')

    epd = epd1in54b.EPD(reset, dc, busy, cs, clk, mosi)

### Displaying data

Consult `main.py` for an example usage.

In order to use fonts, copy them to `epd/lib` directory, or (recommended) freeze them in firmware. See [this blog post](https://kapusta.cc/2018/03/31/epd/) for more info on how to do it.
