Thanks Janos,
I already tried to change this pin but the power consumption increases
to approx. 5.5mA (I suppose because the amplifier is activated).
In particular here is what I made:
1) I first modified MotePlatformP adding:
DDRC = 0x02 ; PORTC = 0x02 ; -> power consumption 5.5mA
DDRC = 0x02 ; PORTC = 0x00 ; -> power consumption 160uA
2) Then I restored the MotePlatformP component and modified NullC by
adding the same lines in Boot.booted with same results.
3) I replace those lines with GeneralO interface (it should be the same,
but just to be sure) and adding GeneralIO.makeOutput; GeneralIO.set() /
clr() , again, with same results.
No luck :(
