For your particular benchmarks, use setPeriodic. Timers fire through
a task, which must wait to be executed in the task queue. With
setOneShot, you are accumulating error. setPeriodic sets the alarms
at periodic times from the previous alarm, giving only jitter with no
accumulation.

Hi, i'm working with Tmote Sky and i'm studiing this scenario: a

slave listen to master's requests and answer waiting its turn. The

Hi!
The Data_Message_PC is encapsulated in the TOS_Msg.data.
The idea is the following: I receive from a mote via radio the following

This data I want to stuff in the field actualData from the Data_Message_PC.

Hi ,
In the reset vector address we place the instruction branch or jump and
even the address to where we have to jump or branch but the address
itself is 32 bits...?
How is it that we are able to accommodate the 32 bits address and even
the instruction in the 32 bits space
Thanks and
I do not think the JUMP or BRANCH instructuon is actually stored in the interrupt vector table. It would be redundant information. Basically the interrupt vector number is used as an index into the interrupt vector table (IVT). The entry at that index will give the 32 bit address to jump to to
I'd suggest reading the MSP430 Family Guide which can be found on the ti.com website. In the section on the ADC12, you will find the registers to setup sample timing through the use of the hardware timers.Matt[EMAIL PROTECTED] wrote: -To: "Cory Sharp" [EMAIL PROTECTED]From: "jagan nath" [EMAIL
Hi all,
I am trying to get the power consumption on tmote

can see that the current consuption is always of20 mA. This means that,

Leonardo,
Yes, .data is considered. Since .data goes
to the ROM, its added to .text. This is what gets printed out.
If youre asking this because you
face some out-of-memory issues, its probably because of the stack
overwriting the top of the .bss. Of course, objudump wont tell you
You should download Boomerang and use SP as your mechanism for turning
the radio on and off.

No. The original poster is correct - .data contains modifiable data
that is stored in RAM. What is stored in ROM is the initial values
Hello
I've just done a few current measurements and compared them to the
datasheet from moteiv
(http://www.moteiv.com/products/docs/tmote-sky-datasheet.pdf)
I can't find out, why my numbers for MCU standby are so far away from
the one in the datasheet (that says 5.1 μA avg., 21μA max.):
We have developed a small application that reads in data from the ADC and
sends this data to the base station which displays it to the computer. We
want to make our application so that it has multi-hop capability. How
exactly do we add multi-hop capability? Do we simply wire a couple of
Yes, I think. Look in tos/lib/Route or tos/lib/MintRoute. Both are
basicially a mote AODV as far as I know. I think it's set up such that
the destination (sink) is whichever mote has ID 0, and it takes care of
sending packets from any node to that sink. You wire to MultiHopM, you'd
have to look at

It means you have _more than one_ component wiring to an event that is
expecting _at most one_ component wiring to it. Expecting at most
one means the event returns some value that is uncombined, so the
signaller receives the return value from only one of the wired
components.

Sleep mode during program execution is LPM3. With the radio off I
have personally and recently measured this at 6uA. Deep sleep means
LPM4 wich can only be woke from an external reset, which is even lower
power.

802.15.4 is using DSSS, with a code that is fixed for a particular
