2.7" E-Paper Display (Embedded Artists)

Hardware
1

So I just got my Spark Core with the initial idea of interfacing it with a 2.7" E-Paper display from Embedded Artists: http://www.embeddedartists.com/products/displays/lcd_27_epaper.php

They have libraries/wiring diagrams for both Arduino and Raspberry Pi, so I was hoping that porting the libraries to the Spark Core would be at least somewhat trivial.

Here’s a PDF showing the wiring on an Arduino: http://www.embeddedartists.com/sites/default/files/support/displays/epaper/Epaper_arduino.pdf

Same PDF, but for Raspberry Pi: http://www.embeddedartists.com/sites/default/files/support/displays/epaper/Epaper_RaspberryPi.pdf

My question is: has anyone out there managed to fiddle with something similar and gotten it to work, or have any tips on if this is even possible with the Spark Core? I’d love to get this thing going, even if just for displaying text of various sizes, but I’m still just a hobbyist when it comes to electronics.

Thanks in advance!

I took a look and it seems like it might not be that straightforward with the Arduino specific code.

Someone else might want to try porting it :smile:

@Didstopia, @kennethlimcp, I may be able to TRY and port this library in the coming week or so. The biggest issue I can see is the shear number of I/O required. It uses SPI plus 7 GPIO control lines AND I2C for the onboard temperature sensor for a total of 12 of the 16 I/O pins on the Spark. Is this what you had in mind @Didstopia?

Oh wow, thanks for the warm welcome, guys!

I’m essentially building a low-power, internet connected analytics display, which will be on 24/7 and only refresh it’s data and redraw every few minutes or so.

Now, I’m not planning on adding any other hardware to the Spark, other than the display, so as long as the IO on the Spark is enough, I’m not complaining. :smirk:

I’d be more than thankful for any kind of help on porting, rewriting or entirely recreating a Spark library for this display, as I’m fairly sure that with time there will be others who want to use the same display. I’m also more than willing to help with the porting, testing and continued development of the integration. :smiley:

Any luck with this? I’m very interested in getting an epaper display working with spark. Doesn’t have to be very fast and while I’d prefer less io pins, i can live with this many.

Hi. Did you managed to port the embedded artist 2.7" display library on the spark core or to get a library that would work for the display?
Thank you.
