Title: I2C pins on AxonII
Post by: Aberg098 on June 24, 2010, 08:45:25 AM

Quick newbie question again:

So which pins on the AxonII corresponds to the SCL and SDA for the I2C connection?

I can see where I2C is labelled on the board, I also know that the outermost (ground) connection is not used.

Have a look at the schematic, it'll be obvious. Unfortunately I couldn't cram all that text directly on the board :-\

If you mean this schematic:

I completely fail to see how this is obvious.

Under the "special headers" part, the first is the I2C header. SCL is in the middle and SDA is on the outside(the opposite one from the GND)
