hi
I tried to install TinyOS2.x to a node by "make install XXX jtag"
this problem comes :
Traceback (most recent call last):
File "/opt/msp430/bin/msp430-jtag", line 16, in ?
from msp430 import memory, jtag
File "/opt/msp430/lib/python2.3/site-packages/msp430/jtag.py", line 44, in
?
raise ImportError("Can't find neither _parjtag nor ctypes. No JTAG
backend available.")
ImportError: Can't find neither _parjtag nor ctypes. No JTAG backend
available.
Anyone can help me ?

Hi,
First of all I am sort of new to MoteView and its capabilities, so bear
with me...
I am supposed to set-up a MoteView demo for high school students. One
thing I would like to show is how the voltage levels of the motes can affect
the network topology (because if one or more motes' voltage levels drop too
far, then they will go down). I would like to be able to show this rather
than turning off one mote to see how the rest of the topology develops, etc.
Thanks!

I didn't know about that chip...pretty cool, but will still only
approximate things based on some set of 'ideal' conditions. I'm
sure we've all had the low-battery warning on some device happen
at seemingly random times before full failure...
But there is a nice app-note on using voltage as a charge indicator:

Subject: [Tinyos-help] Debug messages directly from mote?
To: <[email protected]>
Message-ID: <[EMAIL PROTECTED]>
Content-Type: text/plain; charset="us-ascii"
Hi all,
Is there a possibility or a tool to display debug messages directly from
the
mote, when the mote is connected to the pc and an application is running?
For example just like a tossim simulation, outputs debug messages. The
tools
"Listen" or "ListenRaw" just display "raw" bytes, when a packet is send to
the serial port. Has somebody an idea?
I use the Boomerang 2.0.4 distribution with some Tmote Sky.
Thanks,
Thomas

The TinyOS programming manual (and the nesC reference manual) explain
unique()/uniqueCount().

MoteView merely displays the data as reported by Motes.
The voltage to the Motes is dictated by the batteries that are attached
to the Motes and MoteView has no control over it.
Your best bet would be to use a variable bench power supply to power the
Motes and vary the voltage and notice any topology changes in MoteView.
As long as the battery voltage is held above 2.5V, I wouldn't expect any
topology changes.

And if you dont want to mess around with hardware you may use either
PowerTossim or Avrora to estimate energy usage for each sensor node. You
can
later on use the hardware options to verify if you like.
