Adafruit_EPD_RK

Particle port of the Adafruit EPD (e-paper, e-ink) display library

This library is used to support the Adafruit 2.13" tri-color EPD display (212x104 pixels). It can also be used with other Adafruit EPD displays.

Particle Pin	Display Pin	Description
D2	SDCS	SD card Chip Select, required for communicating with the onboard SD card holder
D3	SRCS	SRAM Chip Select, required for communicating with the onboard RAM chip
D4	ECS	E-Ink Chip Select, required for controlling the display
D5	D/C	E-Ink Data/Command pin, required for controlling the display
MISO	MISO	SPI master in, slave out
MOSI	MOSI	SPI master out, slave in

RST is connected to the hardware reset button, not a GPIO
BUSY is on a pad, but by default not connected to anything

This library is a port of the Adafruit_EPD library.

It also relies on:

Adafruit_GFX_RK, a port of the Adafruit-GFX graphics library.
SdFat, an implementation of the FAT file system on SD card for Particle.

The back of the board looks like this:

And with an Argon inserted:

Example

In order to use the bitmap feature of the display, you'll need to have a FAT formatted micro SD card. Copy the blinka.bmp file to the top level of the SD card, then put it into the SD card slot on the FeatherWing.

You'll need to flash the examples/FeatherWingTest program to your Argon, Boron, or Xenon.

It will display several test patterns:

Text
The Adafruit graphic (if you set up the SD card)

The display only updates every 3 minutes, as the Adafruit documentation warns that the display can be permanently damaged if you refresh it more often than that.
