Using E-ink breakout friend with Pervasive display

[ErikNL]

I recently bought a e-ink friend, I hooked it up to a adafruit feather32 and use the ThinkInk_mono example together with a 2.9"flexible display (this one: https://www.adafruit.com/product/4262)

It worked like a charm (after changing a few pins in the code).
I now also have a 1.54" and 2.66" eink display from Pervasive Displays. I was hoping I could just swap them out for the 2.9"one, but I don't get them to do anything.
Any idea if they could also work with the E-ink breakout friend? and what changes I should make to get them to work?

I’m afraid we don’t know anything about Pervasive displays.

See if you can find a datasheet for them and check the pinouts. Most e-ink displays use the same general protocol, so it may be just a matter of getting the signals to line up.

If that doesn’t work you’ll need to check the protocol itself. If it uses something other than SPI or wants different commands, you’ll probably need to write your own driver. If that’s the case, you can use our library as a design reference. Make it a subclass of Adafruit_GFX and you’ll inherit all of the GFX library’s graphics capability.

Thanks for your reply. I've found the datasheet for the display: https://www.pervasivedisplays.com/wp-co ... 201019.pdf

It does use SPI, but it seems the pinout differs quite a bit from the one used in the e-ink friend that I found here: https://cdn-learn.adafruit.com/assets/a ... 1576775087

So I guess that if I want to test this display, I would need something like a breakout board for the 24pin header.

I might also try to create a custom version of the board that I can use with this display, I found the eagle files here: https://github.com/adafruit/Adafruit-E- ... akout-PCBs , any idea if there is also a BOM available?

any idea if there is also a BOM available?

Our BOMs are written in terms of inventory references that aren’t useful to anyone outside our building, and we buy parts in batches with MOQs (minimum order quantity) of 5000 or more and lead times of several months.

There are plugins you can use to extract a general BOM from an Eagle schematic, but you’ll need to find specific parts you like at Digikey or Mouser. Provisioning is a part of the development process that doesn’t share well.
