I didn´t know you needed external ones also in the case you have internal ones.

I'll end up using the external resistors anyway as a just in case.

The library you linked to is the one I'm using, I honestly have no idea why I was having so much trouble with this thing. It was discouraging to say the least.

Do external pull-ups affect speed of I2C communications at all? I've had it running successfully at 300KHz with no external pull-ups, but that was over a 4-inch run of wire.
