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.

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:

  • Lines
  • 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.
