LilyPad AT328P I2C

Hey guys,

I was wondering whether I can use my I2C gyro (MPU6050; note: it's not the one from Sparkfun) and an I2C temperature sensor to get correct readings on my LilyPad. It's not the USB-model, but after a look at the schematic file, I saw that PC4 and PC5 pin feature SDA and SCL. Well, they are connected to A5 and A4, so the question is: can I use A5 and A4 to communicate with my sensors via I2C?

And what about using the MPU6050 without I2C? Could this work? It doesn't, does it?

Kind regards
Yannik

So, here's a little update:

here in this example MPU-6050 - Elecrow you can see it hooked up to A4 and A5, but what about XDA and XCL pins?

A4 & A5 are the I2C lines, so yes you can.

I forget which of MPU6000 or MPU6050 can also do SPI - not all Lilypad models breakout the SPI pins to do that.
