Again, a confusing post... I'm really needing some sleep. :shock: I was talking about CM5, therefore only AtMega, not XMega... I can't find how to define if the pin is used as UART or as general purpose.

If the UART TX is enabled it takes control of the pin. If the UART isn't enabled you're using the pin in GPIO...

So all i need to do is setting bit 3 of USART Register B to LOW? I'll be trying that tomorrow! Thanks

Hey guys, the experiment is up and running.
However the results are being a little disapointing... Does anyone know the HIGH and LOW voltages for the Ax-12 servos? Our open collector circuit sets the High at 4.66V or 3.66V and Low at 1.5V or 1V, respectively (they are not independent). However, the servos aren't recognized by the CM-5, and we suspect it's because of this values.

Also, our IMU (from huvrobotics) stopped working... it lights the red led at the start but CM-5 doesn't recognize it... I've tried connecting with different wires and in different bus entrances, and still nothing. Any ideas on what to do?

Thanks
