E Ink display tested

Bought E-Ink display

E Ink display and Driver

Connect display and driver

First of all, I tried to search the reference with despi c097 esp8266 to see the cabling between esp8266 and the driver board.

despi c097 esp8266 google search result

Ahhh… there is no reference.

What should I do? I visit, the product page but the page only provides technical specification and schematics. I just want to run a MicroPython code to display. (I found, after a successful result, this is not that kind of simple, like turning on the led)

I re-visited the product page of Aliexpress. there is! a product demo code.

demo code of the product page

I have wemos d1 mini so, I downloaded blabla-ESP8266 sample code.

It is a arduino code. not a micopython code.. opened sample code in arduino ide

Connect the cables that found in the arduino code, Connect cables found in arduino code

There is two more connector that is not specified in the code (SCK and SDI). What I can do is to ask GPT.

Ask gpt about how to connect remaining connectors (first, i mistakenly connected mosi? or miso? to SDI, after changing it, it finally worked.)

FINALLY

the display shows the demo screen!

Finally the display shows sample
