What pins is for I2C?

I have tried to find what pins there are for I2C to use and i can not find a good datasheet for Spark that says that,any help?

Hi @RickardP! Take a look here under the Wire library reference: http://docs.spark.io/#/firmware/communication-wire

Probably not the best name, but it was ported from Arduino, which was ported from Wiring I believe…

Also, the hardware datasheet is in the documentation:


thanks, that was what i needed, someone knows if they did some app for OLED over I2C?

I’ve got a driver for the Digole OLED displays. What display do you have?

I have a Adafruit Monochrome 128x32 I2C OLED graphic display
