Hello,
I'm working with TinyOS 1.1 on a small sensor node using the MSP430
microcontroller. I need to provide a 128 kHz clock to my front-end chip
(chopping amplifier). So, I want to take the 8 MHz signal from the MSP430
XTAL input and to divide it by 64 for having the 128 kHz.
It seems to
Hi
I am using surge as my application. How can I tell it such that only
particular nodes transmit data. I tried to check if the
TOS_LOCAL_ADDRESS == desiredNodeId in SendData() but it doesnt work.
desiredNodeid can be more than 1 address.

Hi. I'm designing an interface for TOSSIM under T2, and I want to perform an
execution log. So I was wandering wheter dbg messages are sent to the
standard output (which I would redirect to my log) or which other way do I
have to use to display dbg messages.
Thanks

I have a table with constant values, so I need to allocate it in ROM for save

My table is in an external file called table.h and I include it on the top of

Hello all,
I am trying to implement Time sync in tinyOS-2.0
For this purpose, i need to set and then read the value of AVR timers.
I tried the application Blink(tinyos-2.x/apps/tests/mica2/Timer).
But the interfaces it is using , no longer exists.
Even, i tried to update the interfaces, like:

If you could send the complete compile output of 'make micaz sim'
that would help.

Are you saying you have some nodes designated repeaters and others
designated sensors?
If so, the simplest way is to set ranges of nodes at the timer start in
SurgeM. e.g. if ( TOS_LOCAL_ADDRESS 20 TOS_LOCAL_ADDRESS 40 ) call
Timer.start(x,x); Otherwise, you will simply be wasting time

Hello,
I used the cc2420lpl stack (the one in tinyos-2.x-contrib/rincon)
together with the multihop-oscilloscope.
My nodes (Tmote sky) run fine for a cupple of minutes, then some nodes
stop working.
Here are some parameters of my network () :
5 nodes, limited tx-power to 2
8s sampling period
Hi,
I am using tmote sky and I am using the Delta application in Boomerang. The
delta application sends one reading per message but I have modified it to send
10 readings per message, I store the reading in an array and then send them,
the code gets compiled but the motes are not sending data
You can only measure voltage in a mote: V = P/I
V= Voltage
I= Current (Ampere)
P= Power (Volt-Amp, Joule, Watt)
Properly, you require an external device connected to the mote that will
supply power and measure power consumption. Power monitoring is both more
difficult, and parasitic.
There is
Interesting. I've been using DMA for all of my projects instead of the
NoDma components to increase radio throughput. If you override your local
Msp430Spi0C and Msp430Spi1C components with those found in
tinyos-2.x-contrib\rincon\tos\chips\msp430\dma does the problem still occur?
I'll test out
Hi,
I'm developing an application to track a mobile node in a sensor network.
My application is facing a problem of packet loss. To start with a very
simple topology, I've taken 3 nodes 0,1, and 2 (2 is the mobile node) on the
following coordinates respectively: (0,0), (10,0) and ( 0.03,0). My

I am using TinyOS 2.0 and the TelosB platform. I have a transmitting node and I
am setting the tx power level on a per packet basis. For the receiving node,
upon reception of a packet I am using the getPower() function in order to record
the power levels of each incoming packet. My issue is
Ah, the actual intended transmit power is not carried in the packet.
The getPower/setPower commands are only useful on the transmitting
node.

I wonder how can I use the digital I/O pins on the expansion connector of the

I know, that I have to populate R14 and R16 to use GIO0 and GIO1. But what

Is there any example of using it?

Hi
You could increase the payload by changing the value of TOSH_DATA_LENGTH in
CC2420.h or do as tep 111 says:
The data field of message_t stores the single-hop packet payload. It is
TOSH_DATA_LENGTH bytes long. The default size is 28 bytes. A TinyOS
application can redefine
Hi Ricardo,
Thanks for your reply - yes it did help. I am aware of modifying this
TOSH_DATA_LENGTH thing, but I was wondering if there was a more efficient
way of handling such a data structure instead of using arrays - in fact most
of my array slots are empty. Nevertheless, I shall stick
