Hi Schematics would be great :)
That was my first idea, that the pin was set to output. After reading the manual MPR-MIB (link sent by Giri) for the MicaZ it apears that: ___________________________________________________________________________ 3. INT2 GPIO Line MICA I/O signal INT2 (Port E, pin 6 on ATMega128 or 51-pin Hirose connector pin 4) is used internally to the MICAz for the CC2420 Radio Receiver FIFO Ready interrupt. Use of INT2 for any other purpose must be done with care. Specifically, the Port configuration (input, active low) must be restored following use in other software modules. ____________________________________________________________________________ Could exist something similar on the IRIS? In the radio code nothing appears....
