Photon I2C Support

Hardware
1

Hi,

I am a noob, but had a specific question regarding the Photon. Does this support I2C. I see there are pins for clk/data but can not see it mentioned in the specs. if not I will use the Argon, but did want the smallest device I could use.

Thanks

Pete

Hmm, which specs have you been looking at?

That would then be the P0 (the chip on the Photon/P1) or the slightly bigger P1 which would be easier to implement.

Thanks. these were the specs I looked at. However that was the only reference I found when I searched I2C, wheras the other pins seem to have more detail.

If it is supported then great, job done.

Thanks for confirmation.
