Is this oled display a SPI or I2C?

I just bought a new oled...I not sure is it I2C Or SPI

Given that there are probably dozens of different OLEDs and you have provided no clue to which one that you have, I do not know how we can help. I usually get the part's data sheet before I buy the part. Just sayin'.

See second item.
That should get you going.
Its not the most friendly forum for pictures but it does work.

Posting tips.

  • Always list the version of the IDE you are using and the board version if applicable.
  • How to insert an image into your post. ( Thanks Robin2 )
  • Add your sketch where applicable but please use CODE TAGS ( </> )
  • Add a SCHEMATIC were needed even if it is hand drawn
  • Add working links to any specific hardware as needed (NOT links to similar items)
  • Guessing is not the best way to describe an issue. Actual facts are the most important.
  • Remember that the people trying to help cannot see your problem so give as much information as you can

A link to where you bought the display may be enough to help us to identify it.

I am unlikely to delete this topic.
The OP just needs to supply better information which I hope he does.
