2.13" ThinkInk Issue
I just received a Adafruit 2.13" Monochrome eInk / ePaper Display FeatherWing - 250x122 Monochrome with SSD1680 PID: 4195. I plugged it into my Adafruit Feather M0 Bluefruit Board and uploaded the ThinkInk_mono demo code and nothing changes on the screen. Is there something special that I need to do. The page for the board has minimal information about pinouts or schematics to validate that the pins are called out/connected correctly. Do you have any suggestions to determine if it is hardware or the demo code?

Re: 2.13" ThinkInk Issue
Did you change the demo to uncomment the correct display constructor call? I.e.
Dave
Code: Select all
// 2.13" Monochrome displays with 250x122 pixels and SSD1680 chipset
//ThinkInk_213_Mono_BN display(EPD_DC, EPD_RESET, EPD_CS, SRAM_CS, EPD_BUSY);

Yes, that is the line I have uncommented. I have also tried the line beneath it to no avail. I am assuming that the pins are in the right location between the boards in the inner rows on both sets of dual-row headers.
Code: Select all
// 2.13" Monochrome displays with 250x122 pixels and SSD1680 chipset
ThinkInk_213_Mono_BN display(EPD_DC, EPD_RESET, EPD_CS, SRAM_CS, EPD_BUSY);
//ThinkInk_213_Mono_B74 display(EPD_DC, EPD_RESET, EPD_CS, SRAM_CS, EPD_BUSY);

Yes, it will only plug in one way.
I would check the soldering of the header on the Feather. Feel free to post clear closeups of the soldering.

Here is a close-up of both sides of the feather. This feather was pulled from a working project to run this test.

Re: 2.13" ThinkInk Issue
Is there anything else to try or do I need to send this back for a replacement? Thank you!
