2.13" ThinkInk Issue

Post by sperry27 »

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?

Did you change the demo to uncomment the correct display constructor call? I.e.

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.

Is there anything else to try or do I need to send this back for a replacement? Thank you!
