The Adafruit Feather ecosystem is so wealthy with {hardware} range, we wished to share them, one every day. In the present day is the Adafruit 2.13″ Monochrome eInk / ePaper Show FeatherWing – 250×122 Monochrome with SSD1680!
Simple e-paper lastly involves your Feather, with this breakout that’s designed to make it a breeze so as to add a monochrome eInk show. Chances are high you’ve seen a type of new-fangled ‘e-readers’ just like the Kindle or Nook. They’ve gigantic digital paper ‘static’ shows – which means the picture stays on the show even when energy is totally disconnected. The picture can also be excessive distinction and really daylight readable. It actually does look similar to printed paper!
We’ve appreciated these shows for a very long time, and so they’re nearly Feather sized, so wouldn’t a customized e-paper FeatherWing make a ton of sense? This ‘Wing is examined to work with all of our Feathers, from the ESP8266 to the M0. It has built-in reminiscence buffering so it may work with chips as small because the ’32u4 and ‘328. It does use a whole lot of pins: the three SPI pins, and as much as 4 management pins to handle the SD card slot and SRAM.
The FeatherWing sports activities a 2.13″ monochrome (black and white) show with 250×122 black pixels on a white-ish background. The monochrome shows take lots much less time to replace than our tri-color e-Ink shows, solely a few seconds as a substitute of 15 seconds!
Utilizing our CircuitPython or Arduino libraries, you possibly can create a ‘body buffer’ with what pixels you wish to have activated after which write that out to the show. Simplest breakouts go away it at that. However for those who do the maths, 250 x 122 pixels x 2 colours = 7.6 KBytes. Which gained’t match into many microcontroller reminiscences. Heck, even for those who do have 32KB of RAM, why waste 8KB?
So we did you a favor and tossed a small SRAM chip on the again. This chip shares the SPI port the eInk show makes use of, so that you solely want one additional pin. And, no extra frame-buffering! You should use the SRAM to arrange no matter you wish to show, then shuffle knowledge from SRAM to eInk if you’re prepared. The library we wrote does all of the be just right for you, you possibly can simply interface with it as if it had been an Adafruit_GFX appropriate show.
We even tossed on a MicroSD socket so you possibly can retailer photos, textual content information, no matter you prefer to show. Comes assembled and examined with socket headers that you may plug your Feather proper into, no soldering required!
