Hello!
I want to use tmote to produce clock of 40KHz,so
I'm trying to capture msp430's clock for a several days, but failed. I think
using interfaces of TimerA0 could work, so I try to use interfaces
MSP430Capture as CaptureA0,MSP430TimerControl as ControlA0,and MSP430Timer as
TimerA. By using
I use a free program COMPump to read the port.
As far as I understand it just listens the port and what I see is a raw
stream of data. This program allows to make log files, and that's
exactly what I need.
I have written a special C-program that processes those log files and
takes into account a
You probably need to use the lower level UART modules, e.g.,
UARTM.nc in T1, but I don't know what they are called in T2.
Search this list for many questions, mostly unanswered, about
using raw UART comm...

This paper http://www.isi.edu/~johnh/PAPERS/Son06a.html would answer
your questions.

Hi,
I am trying to implement a network of 20 synchronous clocks/counters
connected to each other and controlled using TinyOS from a Central
BaseStation. I have been able to implement most of the test applications
and the multihop protocols successfully. I am even able to modify
certain java files
How are you using it? Have u generated ssh key for it? Also what parameters
did u give in following fields?

If this is really intended (it seems like an odd requirement), I would
extract the information generated during the compilation phase and set
values in the corresponding images (see tos-set-symbols) before
programming for later retrieval. Of course, this assumes a static
heap.

You can checkout the RC3 for TinyOS 2.1 from CVS using this command:

Hi Nicola and Paul,
VirutalizeTimerC layers 255 independent timers on top of the lower layer
hardware timer resources
The platform wiring takes care of the wiring. From application code using

Just some things to try...
I'd bet that the message buffer gets reused or erased before your
second send can complete. You may also have trouble calling the
send directly from the done, since done is in an "event"
context which is sometimes tantamount to an interrupt, perhaps
try copying the messa
That is byte stuffing and is part of the serial protocol stack (HDLC? if

What I don't understand is why you even saw them. Are you looking at the
raw stream?

The tantalizing thing is that the CPU leds do operate

suppose it's more trouble than it's worth.

Hi all,
I want to wire two components to ActiveMessageC. Each has AMSend and
Receive interface, but their AM id are different. I found that only one
component received messages.
Could someone help me?

I would be more interested in the effects of radition propagation
patterns (not signal inference) and environmental factors.

For TinyOS 2.x see VirtualizeTimerC.
I believe `new TimerMilliC()`, has the same affect, but allows a
different way to wire.
There is a different between hardware-level HPL/HAL timers and the
exposed software timers in the HIL.

Surely the longer the distance, the weaker the RSSI. Besides, if
several senders are sending, due to the overlapping and the phase
differences of signals, isn't it possible that the receiver may
sometimes detect a stronger and sometimes a weaker RSSI than only one
sender is sending?

Please take a look at CTP, which replaces Multihop communicatio
The timer is all right.
I realized what was the problem.
Serial port communication played a trick on me. The program which I used
to read the port gave out data bytes 0x7E and 0x7D as 0x7D 0x5E and 0x7D
0x5D. This is because byte 0x7E is reserved as a frame delimiter, and
0x7D is reserved as a
Hi everybody,
just a short question to the micaz platform. Is the number of timers I
can use limited? I read in TEP102 that there are only three compare
registers for each of the 16-bit timers. Does this mean that I can use
only 6 timers at a time? Or does TinyOS provide some kind of
virtualizatio

I was wondering if there is a multihop communication component in TinyOS 2.x
like the GenericCommPromiscuous in TinyOS 1.x. Can anyone please help ?
