Data or programming help for 0.95' I2C OLED

I have a 0.95 inch OLED display which looks to have I2C bus. How it is programmed without libraries?
Display has these pins:GND, VCC, SCL, SDA, RES, DC, and CS. To me, these look like I2C bus. I have ST's ARM, so I have to do SW myself if I must.

My motor car is a sort of Blue-Grey. What are you going to do about it ?

If you want help with your OLED please post a link to the actual item on your desk e.g. Ebay sale page. (you are not a new member)

We need to see the pcb to identify it. A link is better than a photo.
