128x64 1.3 inch OLED Grafik Screen 6 Pin IS-SPI I can't find your screen's library

Have you tried this library?

It does SPI (DC, RST, CS).

it is very strange that there is no CS pin on my screen. Could it be a problem with it?

it didn't work

The reset pin has to be something other then -1 as your screen has RST(reset), also you need to set the solder blob(red circle) on the back to select I2C or SPI.



This is my screen. It is not compatible with the picture on the seller. If I can return it, do you think I should return it? Or should I try?

OK, SPI screen you need to use the Library @xfpd suggested in post #22.

Pinout is as follows
D0 is CLK or SCK.
D1 is MOSI.
RES is RESET.
DC is DC.

Return it if you like, but no harm with trying. :wink:
