Hi!
I find a mistake that may result the
problem.
In
xbow/tos/lib/CC2420RadioAck/CC2420ControlM
SetRFPower:
gCurrentParameters[CP_TXCTRL] =
(gCurrentParameters[CP_FSCTRL] & 0xfff0) | (power <<
CC2420_TXCTRL_PAPWR);
I think the right hex is 0xff00 instead
of 0xfff0, so I get the RFindex at 5 bits instead of 4, and can count until 31
insead of 15
GetRFPower:
return (gCurrentParameters[CP_TXCTRL] &
0x000f); //rfpower;
I think the right hex is 0x00ff instead
of 0x000f, so I get the RFindex at 5 bits instead of 4, and can count until 31
insead of 15
It is working seemingly.
Do you think it is the right solving and so there is a mistake at
TinyOS 1.x?
Thanks,
Laci

TinyOs 1.x
Hi All!
I'm useing micaz, MIB520 programmer and TinyOS
1.x
I tried to set the RF power by this
code:
uint8_t set_power;
set_power = 15;
call
CC2420Control.SetRFPower(set_power);
using call CC2420Control.GetRFPower();
I monitoring the getted power by MessageCenter,
but I see, only can set the power index between 1 to 15 insted of 1 to
31. If I try to set - for example - 25, it set a random index for
example: 9 or 4.
Does somebody know why?
What will be happen when I try to set higher
index, than the battery can make (because the battery is too low
already)? (Do not set and leave the last index??)
Thanks!
Laci
