Hi all,
I have a bit questions about mcombine() in McuSleepC.nc .
tos/chips/atm128/McuSleepC.nc:100 :
powerState = mcombine(getPowerState(), call McuPowerOverride.lowestState());
tos/chips/atm128/atm128hardware.h:132
mcu_power_t mcombine(mcu_power_t m1, mcu_power_t m2) {
return (m1 < m2)? m1: m2;
}
If the McuPowerOverride.lowestState() if fan-outed to HplAtm128Timer0AsyncP and
my application (AppC), is it going to be :
powerState = ( getPowerState() < call
HplAtm128Timer0AsyncP.McuPowerOverride.lowestState() ) ? getPowerState() :
HplAtm128Timer0AsyncP.McuPowerOverride.lowestState();
//and
powerState = ( getPowerState() < call AppC.McuPowerOverride.lowestState() ) ?
getPowerState() : AppC.McuPowerOverride.lowestState();
Is it true ?
If so, according to Sec 5.2 TinyOS Programming, the order of the combined
functions is
uncertain. How do I know which value that will be passed into the powerState ?
TIA
Regards,
-daniel
