Waveshare 1.54" e-paper. i need help to connect this to arduino uno.

Hello, i bought this e paper module for arduino uno. according to their their wiki page it must be connected according to the pinout table. i did it. i uploaded library too but it wont work. what can go wrong with uno?
screen has been shipped with the latest image on it. i says monday 18:00 etc... i even cant reset the screen.
demo code uploads to uno, but nothing happens.

1.52" wiki

there must be a trick to operate this screen. bigger version of this screen has different pinouts.

any help is highly appreciated.

Hi,

I had just ordered one of these 3 days ago. So it will take ~2 weeks until I can help.
I have experience with the display itself, it seems to be the GDEP015OC1 that I bought with demo board from Dalian Good Display. So I may already have my own display class for it, a unfinished version.

Reset does not clear the display, it only resets the controller.

Make sure you have selected 4 line SPI mode (BS to GND).
I assume you have made the connections according to the wiki info.

i asked the same thing to the customer service because oled screens have 4 pins. they have a nice aftermarket sales they said that we would have all pins connected on arduino uno.

i need to try oncemore.
