Re: [Tinyos-help] Increasing Baudrate for Atmega-128

[Andrey Gursky]

Hello Varun!

In my answer to you

https://www.millennium.berkeley.edu/pipermail/tinyos-help/2008-July/034704.html

there was already a link to

http://mail.millennium.berkeley.edu/pipermail/tinyos-help/2008-June/034373.html

where the problem is solved.

It is strange but the standard speed 256000 is not declared in the 
tinyos implementation of serial communication. That's why I used 230400.

Re: [Tinyos-help] Undefined reference to pow and sqrt functions in telosb!!!

You must link in the math library (-lm) -- also support may be

Re: [Tinyos-help] Problem with tinyos.jar

[Paul Stickney]

Odd.
What happens when you try to access the jar directly (via the jar command)?
Is it somehow corrupt? Really strange permissions? Non existant?

[Antonio Prados Vilchez]

I connected a 10K resistor between SCL (CLK in MDA300) and Vcc and another 
between SDA (DATA in MDA300) and Vcc, but it didn't work. Using the MTS300 to 
communicate with the microphone and magnetometer through the I2C interface, it 
happens the same, event I2CPacket.writeDone is not signaled, and I think they 
have the pull-up network implemented. Any ideas??

Thanks for your help.

You have to add a pull-up network to both I2C lines Data and Clk. On the MDA300 
board, just put a 10kOhm resistor between the Data and Vcc pins, and another 
one between Clk and Vcc.

Thanks for your help Christopher.

I'm following the steps to read from the ADC ADS7828 in the MDA300 board, using 
the I2C interface. However, event I2CPacket.writeDone never occurs. I thought 
that it could be because of a mistake in my code, but I did a bit of research 
about the sensors of the MTS300 sensorboard which use the I2C interface 
(Microphone and magnetometer). In those components it also happens, the event 
I2CPacket.writeDone is never signaled. Does anybody know how to solve this 
problem?

Thanks in advance.

You also need to use the interface Resource from the Atm128I2CMasterC component.
Here are the steps you will need to do: Resource.request, wait for 
Resource.granted, I2C.write, wait for I2C.writeDone, I2C.read, wait for 
I2C.readDone, Resource.release.  It's important that you release the I2C 
resource especially if you have other components relying on it.

Thanks for your help, Christopher.

Now I'm trying to use the I2C interface, as you said, but it doesn´t work. I 
get a lot of compiling errors in the I2CPacket and Atm128I2CMasterC files, so I 
think it's because of the instantiation. Am I doing it right? Should I upgrade 
my TinyOS files to a newer version? The way I instantiate these interfaces and 
components is:
---
implementation
{
...
components new Atm128I2CMasterC();

...   
App.I2CPacket -> Atm128I2CMasterC;
}

---
module SensorToRadioC
{
uses
{
...
interface I2CPacket;
}
}

Thanks in advance

[Tinyos-help] Question about nx_structs in C

[Ashik Manandhar]

Hi,

I am currently using TinyOS 1.1, and am using the serial forwarder program
to forward messages from my motes to a specific C file.  I want get data
from these messages since they are a known message type, but I don't know
how to incorporate this nx_struct into my C code.  Does anyone know how to
this, or if there is another dynamic way to do this?

[Tinyos-help] Random Backoff Delays in TinyOS 2.x Channel Access

[Anton]

Hello!

There is probable bug in the 
/tinyos-2.x/tos/chips/cc2420/csma/CC2420CsmaP.nc (lines 218 and 225)

Communicating wireless modules should wait some random delay before 
performing Clear Channel Assess.
According to the IEEE 802.15.4 standard, that delay should be   
random(2^BE-1)   backoff periods, where BE can vary from 3 to 5 (the 
default values macMinBE and macMaxBE, IEEE 802.15.4-2006, pages 
163-164). This means that for CC2420 the maximum backoff delay is 31*320 
= 9920 microseconds (when BE=5), and the maximum initial backoff delay 
is 7*320 = 2240 microseconds (since initially BE=3).

But according to CC2420CsmaP.nc file the maximum initial backoff delay 
can be around 9765 microseconds (line 218) and maximum congestion 
backoff delay can be around 2441 microseconds (line 225).
It seems that the ranges of these random delays are swapped. Even in 
TinyOS 1.x the range of the initial delay is smaller than that of 
congestion backoff delay 
(/tinyos-1.x/tos/lib/CC2420Radio/CC2420RadioM.nc, lines 745 and 752). In 
TinyOS 2.x this is conversely.

Also, according to the standard the range of the random delay should 
expand (by default BE should change from 3 to 5) each time the channel 
is sensed busy (CSMA/CA algorithm - page 172 of the standard). But the 
range of all random delays is constant both in TinyOS 1.x and TinyOS 2.x.

Please, tell whether it is bug or not.

Kind regards,

Anton.

please remove or make sure it appears in the correct subdirectory of the

Matlab matlab = null;// this is the com.mathworks.jmi.Matlab class,which has

This looks to me like it's a problem with the java code, not my environment

problem.  Please help!!

[Tinyos-help] External hardware component using SPI

[Gonçalo Teixeira]

Dear Dr. Philip Levis,

I'm working on a school project where there's the need to add a hardware
component - an ADC - to micaz, using SPI. I've been looking for answers in
the mailing list archive and i've found 2. In the most recent one, someone
questioned you if you could share your code  and your circuit diagram. Since
i'm completely novice in this kind of matter, i wonder if you could be kind
enough to send it to me as well, as i would learn a lot from an example of
such implementation. Here's the previous answer for the same matter:
http://mail.millennium.berkeley.edu/pipermail/tinyos-help/2008-April/032819.html

[Tinyos-help] LowPowerListening DutyCycle with mica2 motes

[shalini k.s]

I am trying to implement duty cycle on mica2 motes. I have a few doubts to 
clarify and I 
 need your help.
 
 Following are the few doubts related to duty cycle:
 
 1. How do we set the radio duty cycle to 1%( i have included
 call LowPowerListening.setLocalDutyCycle(100) in the application).
 Is this correct?
 
 2. What is the significance of the constants TIME_AFTER_CHECK  and
CC1K_LPL_CHECK_TIME.
 
 3. How is the parameter 100 (for 1%) set in the application converted to 1% 
dutycycle.
 
 Thanks and regards,
 Shalini.

Hello every body

 I have implented an algorithm on TOSSIM , in which nodes broadcat a

Now I'm trying to do a very simple algorithm where there 2 nodes, node
1 send a message to node 2 and node 2 displays a message when receiving.

But the event senDone is neiver signal (I have put a message to be print),
 I don't understand , i also try BlinkToRadioC (found in the Mote-mote_radio
communication tutorial) and adding a printing message in send done, nothing
occurs??

Is there some nuance I don't realize? 


Here is the cpp code I use to run the BlinkToRadioC simulation

#include

//number of motes
int nbCapteurs=2;

int main(int argc,char **argv)

I'm having trouble with the differential ones, I thought I could call the

[Tinyos-help] Time in Trickle

[Jimmy Lee]

Hi, everyone:

  I've read the Trickle implementation code
(\tos\lib\net\TrickleTimerImplP.nc) in 2.X.

  And I'm puzzled by the variable "time" in this code.

  This is the defination of struct "trickle_t":
  typedef struct {
uint16_t period;
uint32_t time;
uint32_t remainder;
uint8_t count;
  } trickle_t;


  I wonder about what the "time" and "remainder" means?

  Also, at the function "adjustTimer()", I have some  questions.

event void Timer.fired()
{
uint8_t i;
uint32_t dt = call Timer.getdt();

for (i = 0; i < count; i++)
{
  uint32_t remaining = trickles[i].time;//What does the remaining mean?
  if (remaining != 0)
{
  remaining -= dt;// Does this make remaining negative?
  if (remaining == 0)

{
  if (trickles[i].count < k)
{
  atomic
{
call Pending.set(i);
  }
  post timerTask();
  }

generateTime(i);

   /* Note that this logic is not the exact trickle algorithm.
* Rather than C being reset at the beginning of an interval,
* it is being reset at a firing point. This means that the
* listening period, rather than of length tau/2, is in the
* range [tau/2, tau].
*/


trickles[i].count = 0;//
   }
   else
{
trickles[i].time = remaining;//So trickles[i].time becomes
negative?
   }
  }
  }
adjustTimer();
  }

[Tinyos-help] Dear Sir, need help in programming Micaz

[zhia howe chong]

HI Sir,

I am a beginner in this micaz and mda320 devices. So far, i have acquired 4
micaz motes and 4 mda320 platform from my supervisor. Now, my task is to
setup a WSN, where each of the motes will take data for different readings
and different places, and whicn be setup easily.

I have done the first part by just connecting sensor to AD0 port, and the
reading of the data will be displayed in VOLTAGE in Moteview. I have done
some conversion of the reading through formula provided by the sensor
vendors.

Next, my project critical part is this. I have to program the motes so tat
one of the mote, which connects to the mda320, will do counter purpose. Let
say, i connect a rain gauge to that platform, so for every 10 drops of rain,
the MDA320 will count the number of rain drops. So, let say my Mote 2 to
Mote 4 are taking data for the temperature at an interval of 30 minutes,
after 10 drops of rain, the Motes will reduce the interval time to 20
minutes in data recording. When there are even more frequent of rain drops,
the interval time for Mote 2  to Mote 4 will change to 10 minutes of
interval time to take reading. How can i achieve this objective?

Can i use Motework in WIndow XP? How can i edit the binary files using
TinyOS?

Can sir lead me to this in a step-by-step manner? i would appreciate it a
lot.

Best Regards,

[Tinyos-help] Size Code problem

[Roger Potter]

Hello,
it is my first mail.
I'm interested in knowing if there is any size code limitation, because I am 
developing an app of more than 1000 lines and during the test i see that 
tossim  does not execute well parts of the code that alone goes well or has 
been  tested by others member of the tinyos community.
Thanks for your time,

Hello

Hope you will be fine. Actually i doing my B.E final year project on wsn. I

[Tinyos-help] Differential Analog Channels

I'm using an MDA320 on an iris mote. I want to be able to use the differential

Re: [Tinyos-help] boomerang lowpower mesh

[david henry]

 The macro UARTDETECT_POLL is set to 3 seconds, so the base expects a
UartDetectMsg message before that. The Trawler application sends the message
every 2 secs. If you are sending only every 5 secs it would explain why UART
detect requests keep appearing.

I also have the problem where the base station sometimes 'locks up'. If you
connect the base station to Serial Forwarder and then open up Trawler (via
SF) you will see that the 'packets written' counter increments every 2 secs
(as it should). After a random time I start getting a Write Failed message
in the SF window, again every 2 secs. This problem happens both with and
without the lowpower compile option.

 Apropos your comment about receiving messages that were queued up, isn't
that what is supposed to happen?

Finally I spotted another issue which may or may not be relevant to you. I
am using heterogeneous hardware. My base station is a telosb and the motes
are homebrewed. Netsync has a mechanism to detect slippage between the 32KHz
clocks of the base station and the mote. With a heterogenous system its
probaby more likely to happen as the 32KHz crystals were sourced
differently. Making a base station based upon my homebrew is a bit difficult
as the UART1 lines are inaccesible. Even if I could I'm not convinced that a
heterogeneous net would not exhibit slippage between crystals.

[Tinyos-help] About resource arbitration between Uart0 and Radio on telosb mote

[Kirak, Hong]

Hello, guys,

 

I'm making a program which uses radio and uart0 on the telosb mote.

 

Since the radio and uart0 share bus on telosb, I had to deal with resource
arbitration.

 

The thing is, when I made an uart0 manager like this, it dosen't work.

 

More specifically, after some time, I never receive sendDone() signal after
I send() and got a SUCCESS return value, 

 

So the entire program is collapsed.

 


--

  task void requestTask()

  {

call UartResource.request();

  }

 

  async event void UartRequested.requested()

  {

UartResource.releaseTask();

post requestTask();

  }

 

  async event void UartRequested.immediateRequested()

  {

UartResource.releaseTask();

post requestTask();

 

  }


--

 

I know it's greedy, because everytime it releases, it requests again.

 

But as I know about CC2420 on telosb, it should work.

 

Anyway, I tried another case like following, and it works!

 


--

  

  event void RadioSend.sendDone[am_id_t id](message_t* msg, error_t error) {

 

post requestTask();

}

 

  task void requestTask()

  {

call UartResource.request();

  }

 

  async event void UartRequested.requested()

  {

UartResource.releaseTask();

  }

 

  async event void UartRequested.immediateRequested()

  {

UartResource.releaseTask();

  }


--

 

It seems much less greedy since it only tries to grab the resource after
sendDone() has signaled.

 

Does anybody can answer me about the problem with case 1?

 

And in addition, why the CC2420 releases the resource between send() and
sendDone()?

 

Thanks.

 

With Kind Regards,

Kirak

[Tinyos-help] Disable backoff CC2420 tmote sky

[Alessandro Camillo']

I am wondering if disabling CCA check before sending a packet also 
implies that i will not be able to detect collision.

If am not interested in detecting collision i would see CCA to false. 
But checking CC2420 radio stack and precisely in attemptSend()
it seems that the stack just send the packet, using either STXONCCA or 
STXON, but still manages congestions even if
m_cca was set to false. I past a piece of code from the 
CC2420TransmitP.nc module

>   status = m_cca ? call STXONCCA.strobe() : call STXON.strobe();

Shouldn't the last if (congestion) be executed if and only if CCA was 
set to true and congestion detected? The default value of congestion is 
TRUE.

[Tinyos-help] How to design a hardware platform

[dum dummy]

Hi,

I have a basic question; not sure it belongs to which list, if it belongs
here at all. But I think some of you can give me some pointers.

How do I go about designing a hardware platform that would run software? I
am well versed in designing "hardware" that do not run any software (e.g.,
amplifiers; combinatorial circuits, etc.). I am also well versed in software
(that I run on PC). What I do not know is the glue (bootloader/BIOS?). I am
assuming that there is a standard way of doing it. But somehow I could not
find any resource (books or online documents) that explain that. For
concreteness, suppose that I want to design a system with an  OMAP processor
and 802.11g wireless. I can get the processors, RAM, crystal and wireless
chips. I am pretty sure that I can design a circuit board to connect them,
as per the data sheet. Now what? How does the "cold-start" work? How do I
configure the system (both my board and the PC) so that I can download
codes? There must be some software running on the board that would download
the code via a USB/serial cable. How is *that* code first downloaded (kind
of a chichen-and-egg problem :) )? Do the processors "come" with such a
code? Next, how is the 802.11g chip "recognized"?

Any pointer is appreciated (book, online site, academic courses that cover
this...).

Thanks.

nx_uint8_t taskId;
nx_uint8_t eventId;
} subscriber_t;

subscriber_t sub = {1,2};

but the compiler keeps giving me theses warnings:

source/TestListP.nc:30: warning: missing braces around initializer
source/TestListP.nc:30: warning: (near initialization for `sub.taskId')


The initialization doesn't generate warnings if I take away the "nx_"
prefix keyword from the whole structure.

Thanks,
Symon.

[Tinyos-help] pb with rssi and mig with micaz on tinyos2

[Plaçais Pierre]

Hello,
I work on a wireless sensing network with micaz. I use tinyos2 on xubuntos.

For my project, I need the rssi value. I have used the function get.rssi( ) but 
I have some questions:

What is the format of the rssi value (int8_t, int16_t, uint16_t) and how 
convert the value to found a value in dBm?

And I have an other problem with mig function.
When I use java net.tinyos.tools.MsgReader -comm network@:
I have just yriting on the screen network@: :resynchronising and 
nothing happened.

Thanks for your answers.
Cordially.

[Tinyos-help] a little question about SENSORBOARD and make

[Javier Almansa Sobrino]

Hi. I'm trying to program a mica2 with this command:

SENSORBOARD=mts300 make mica2.0x1001 install mib510,/dev/ttyS0

the problem is that it doesn't do nothing, absolutely nothing. If I try

SENSORBOARD=mts300 make mica2 install mib510,/dev/ttyS0

it compiles and load the program into the mica2, but I can't give a
specific node id to the mica.
Also if I try

make mica2.0x1001 mib510,/dev/ttyS0

it tryes to compile and load (obviously it can't because it doesn't
found the sensor modules required by my application).

and with

SENSORBOARD=mts300 make mica2
make mica2.0x1001 reinstall mib510,/dev/ttyS0

I can compile but I can't load the program into mica2 flash

someone knows how to compile with a specific node id and a specific
sensorboard?

thanks in advance

JTAG is one of the more widespread way to program "cold" hardware, most of the 
existing cpu/microcontrollers have one. 
Other than that (disclaimer not all info here has been checked) some hardware 
can come with it's own protocol/bus in hardware i.e.  :
- AVR parallel/serial/spi programming ( see the section called "memory 
programming" p288 of Atmega128 datasheet)

or present as software in some dedicated place such as  :
- bsl in the msp430 (telosb) 
- sam bootloader in some arm7 CPU by Atmel 


> Next, how is the 802.11g chip "recognized"?

well the simplest is to design the software according to the platform 
otherwise if you have no idea run linux, but then you are completely out of 
topic from this list ...

I don't think the microphone and the magnetometer on the MTS300 use the I2C 
bus. Try using the digital pins on the MDA300 because it uses the I2C bus. To 
write to it, just send the value of the 8 pins to address 63.

I connected a 10K resistor between SCL (CLK in MDA300) and Vcc and another 
between SDA (DATA in MDA300) and Vcc, but it didn't work. Using the MTS300 to 
communicate with the microphone and magnetometer through the I2C interface, it 
happens the same, event I2CPacket.writeDone is not signaled, and I think they 
have the pull-up network implemented. Any ideas??

Thanks for your help.

You have to add a pull-up network to both I2C lines Data and Clk. On the MDA300 
board, just put a 10kOhm resistor between the Data and Vcc pins, and another 
one between Clk and Vcc.

Thanks for your help Christopher.

I'm following the steps to read from the ADC ADS7828 in the MDA300 board, using 
the I2C interface. However, event I2CPacket.writeDone never occurs. I thought 
that it could be because of a mistake in my code, but I did a bit of research 
about the sensors of the MTS300 sensorboard which use the I2C interface 
(Microphone and magnetometer). In those components it also happens, the event 
I2CPacket.writeDone is never signaled. Does anybody know how to solve this 
problem?

Thanks in advance.

You also need to use the interface Resource from the Atm128I2CMasterC component.
Here are the steps you will need to do: Resource.request, wait for 
Resource.granted, I2C.write, wait for I2C.writeDone, I2C.read, wait for 
I2C.readDone, Resource.release.  It's important that you release the I2C 
resource especially if you have other components relying on it.

Thanks for your help, Christopher.

Now I'm trying to use the I2C interface, as you said, but it doesn´t work. I 
get a lot of compiling errors in the I2CPacket and Atm128I2CMasterC files, so I 
think it's because of the instantiation. Am I doing it right? Should I upgrade 
my TinyOS files to a newer version? The way I instantiate these interfaces and 
components is:
---
implementation
{
...
components new Atm128I2CMasterC();

...  
App.I2CPacket -> Atm128I2CMasterC;
}

---
module SensorToRadioC
{
uses
{

Re: [Tinyos-help] [Tinyos-devel] How to design a hardware platform

[shankar satish]

Hi,

Essentially, you need to know the science/art of firmware development.
There is no *standard* way of going about it: it all depends on the hardware
platform/microprocessor you are stating off with.

In any board, on reset, all register values and data pointer assume
pre-defined values. (Only you, the h/w designer knows these values). The
first instruction that is fetched by the uP (always written in assebly) is
of the type JMP . After jumping, the uP executes the "startup" code
(again written in assembly). The start-up code finally points to the rest of
the application, which is usually written in C.


Since you want to develop a board from absolute scratch, the best way to go
about it would be by reading the processor's datasheet. Generally speaking,
the more customized your board is, the more difficult it gets to find
information on the API's for firmware development: it eventually degenerates
to a black art.

It might be useful to do a google book search on topics like "embedded linux
development", "embedded firmware development", etc. Most firmware today is
written in assembly and C. It might be worth looking at the "Forth"
programming language. Bootloaders for a wide veriety of platforms have been
developed in Forth.

I too want to know more about how one goes about developing boards from
scratch. Please post any additional info you come across.

Thank you.

-Regards,
Shankar.

Re: [Tinyos-help] about Broadcast component in tinyos2.x

[jiwen zhang]

Hello :
   that is to say Dissemination is a substitutor of Broadcast in tinyos1.x ?


  i have spend some time researching the Dissemination , i have a question
:

  in my opinion , once the Disseminator disseminate a data , it will
increase the sequence number , for example , if the disseminator's nodeid is
0, after two times's disseminations , the the sequence number should be
0x0002 , so the whole network maintains the same sequence number
(assuming there is only one disseminator), and at this time the disseminator
is rebooted for some reason , so the sequence number is reset to zero , so
when it disseminates new datas to the network , the other nodes maybe
discard the new data . how does the Dissemination resolve the problem ?

[Tinyos-help] Strange Ranges of Random Backoff Delays

[Anton]

Hello!

There is something in the 
/tinyos-2.x/tos/chips/cc2420/csma/CC2420CsmaP.nc (lines 218 and 225), 
which I don't understand.

Communicating wireless modules should wait some random delay before 
performing Clear Channel Assess.
According to the IEEE 802.15.4 standard, that delay should be   
random(2^BE-1)   backoff periods, where BE can vary from 3 to 5 (the 
default values macMinBE and macMaxBE, IEEE 802.15.4-2006, pages 
163-164). This means that for CC2420 the maximum backoff delay is 31*320 
= 9920 microseconds (when BE=5), and the maximum initial backoff delay 
is 7*320 = 2240 microseconds (since initially BE=3).

But according to CC2420CsmaP.nc file the maximum initial backoff delay 
can be around 9765 microseconds (line 218) and maximum congestion 
backoff delay can be around 2441 microseconds (line 225). So, the range 
of congestion backoff delay is shorter than that of initial backoff delay.


Of course, if BE (mentioned in the standard) is initially set to 5, the 
range of the initial backoff delay should be 9920 microseconds. But in 
such a case, all subsequent congestion backoff delays which might happen 
should take on some value within the same range (according to standard 
CSMA-CA algorithm).

Could anybody explain it?

Thanks.

Anton.

[Tinyos-help] TestNetwork scripts for parsing debug messages

[Gaurav Chandwani]

Hi,

I have installed TestNetwork on many telosb motes(am using  2.0.2 release).
Where can I find the scripts to parse the debug messages sent by
these nodes ?
In the readme on CVS, its written that they should be available on net2 website,
but am unable to open it ?
I believe test.py is just a simulation script or it has any relevance
in parsing ?

Best Regards,
GC

Re: [Tinyos-help] a question about TYMO protocol

[Romain Thouvenin]

See my first response:

I think it is because you need to create the StorageVolumes.h file in
the RadioSenseToLeds directory.
You can have a look at the storage tutorial to know what this is
about, and look in apps/tests/TestTymo/StorageVolumes.h to have
correct values

Moreover, make sure you use the latest TinyOS CVS code, NOT the code
from the tymo project of sourceforge.

Hope this helps,
Romain

Re: [Tinyos-help] Differential Analog Channels on MDA320 with TinyOS 1

Hi Tom,

Change lines 170-200 in XMDA320M.nc. I think you just have to change the
first parameter in the function Sample.getSample(...) to the number
corresponding to the differential channels. That's about all I can say
without trying to understand the messy code in MDA320 driver folder.

[Tinyos-help] Problem in printf library

[Shikhar Sachan]

Hello Users,

I had been using the printf library and the printfs worked absolutely
fine ... however ... after I changed the default msg size from 28
bytes to 42 bytes (TOSH_DATA_LENGTH 28) my printfs have started
giving me problems ... I have no idea why this is happening.
The printing skips some characters.  I donot how changing length of
messages could affect printfs. I hope I am able to find a solution.

No, it is not a bug. TinyOS does not have an 802.15.4 MAC.

[Anton]

Thanks for the reply,

but why the range of the congestion delay is shorter than that of 
initial delay?
Isn't it natural to increase the range of backoff delays when the 
channel is not clear?

Re: [Tinyos-help] Problem in printf library

[Kevin Klues]

If you are printing stuff out in quick succession, it may be due to
the fact that the 'old' printf library will fail any attempt to print
characters while in the middle of flushing out a message.  With loner
messages this takes more time, and it is therefore more likely that
characters may be lost.  The newest version of printf (i.e. the one in
the cvs HEAD doesn't have this problem anymore).

[Tinyos-help] basic radio communication

[Florentin vf]

Hi,
 
I'm using tinyos 1.x with the Cricket system, and I want to send a radio 
message from one mote to another. I only need to send one decimal digit, but I 
am having problems. I've tried going through the radio tutorials but don't 
understand them. I've also tried imitating the format of other messages that 
are being sent in the Cricket code, to no avail. 
 
All I need to do is make it so that, when prompted through the serial input 
with "P BE %d" the radio sends %d to another mote, which acts on it. Here are 
some examples of what I am trying:
 
 
else if (!strncmp("BE", pos+2, 2)) { 
//**
beacon_calldata->x = atoi(pos+4);
beacon_calldata->y = 0;
beacon_calldata->z = 0;
beacon_calldata->temp = 0;
beacon_calldata->tb = FALSE;

call RadioControl.start();
TOSH_uwait(2000); 
call RadioSend.send(&beacon_call);


  }
 
 
 
 
  event TOS_MsgPtr RadioReceive.receive(TOS_MsgPtr data) {
uint8_t i;
 
int result = 0;
int count = 0;
//uint16_t FailedAttemptComp;
//char OutputMsg[128];
 
 
else if (CricketConfig.run_mode == MODE_BEACON){

struct CricketBeacon * beac = (struct CricketBeacon *)data->data;

call Leds.greenToggle();  

if(beac->x == '4')
  {call Leds.redToggle();}
  
  
if (beac->x ==(int)(CricketConfig.spaceid[6]-48))   
//***
{
  call RadioControl.start();
  TOSH_uwait(2000);
 
  if (CricketConfig.run_mode == MODE_BEACON) 
  {
while ( count < CricketConfig.max_beacon_number - 1)
{
  atomic

Please describe the problem in more detail. "Not working properly" is  
hard to work with. E.g., send an example simple app to the list where  
timers don't do what they are supposed to.

[Tinyos-help] change TelosB Radio range

[Mr Meddage Saliya Ranal Fernando]

Dear all,

I’m new to TinyOS, can you please let me know how to change the radio 
power in a TelosB mote? Can that be done when i'm injecting the program 
to the mote or have I got to do it in a particular file?


Thank you,

Re: [Tinyos-help] Initializing an nx_struct

[Eric Decker]

A nx_struct is actually defined as a structure of byte arrays.

So you would need something like

subscriber_t sub[{1}, {2}};

that is what is going on.

Re: [Tinyos-help] How to get the transmission power of the received Packet

[Nilesh Mishra]

I think you will have to put this information somewhere in the data field of
the packet. The RSSI measured at receiver is receiver's signal strength and
different senders (at different power levels) can give same RSSI value
depending on environment and other parameters, hence you will have to
include the transmission power in the data at the time of transmission.

[Tinyos-help] Uart0 Serial Stack as Default Owner of Arbiter

[Kirak, Hong]

Hi, guys,

 

I am struggling with some resource arbitration problem with CC2420 and
UART0.

 

What I want to do is, making  UART0 serial stack as a default owner of USART
bus.

 

But it looks like it is not enough that I just connect default owner
interface to serial stack because it seems like it checks resource id.

 

Is there any way to use original serial stack as a default owner?

 

Thanks,

Hello David,
 
Yes, you can install MoteWorks on WinXP OS.
You can not edit the binary files included in MoteView. Instead, you
will need to edit the application source code available under MoteWorks
(eg. \opt\MoteWorks\apps\xmesh\XMDA320).
 
Attached is an outline of steps involved in reading the counter channel
(Courtesy: Ian McCulley @ DPI).
 
I hope that helps,

HI Sir,
 
I am a beginner in this micaz and mda320 devices. So far, i have
acquired 4 micaz motes and 4 mda320 platform from my supervisor. Now, my
task is to setup a WSN, where each of the motes will take data for
different readings and different places, and whicn be setup easily. 
 
I have done the first part by just connecting sensor to AD0 port, and
the reading of the data will be displayed in VOLTAGE in Moteview. I have
done some conversion of the reading through formula provided by the
sensor vendors. 
 
Next, my project critical part is this. I have to program the motes so
tat one of the mote, which connects to the mda320, will do counter
purpose. Let say, i connect a rain gauge to that platform, so for every
10 drops of rain, the MDA320 will count the number of rain drops. So,
let say my Mote 2 to Mote 4 are taking data for the temperature at an
interval of 30 minutes, after 10 drops of rain, the Motes will reduce
the interval time to 20 minutes in data recording. When there are even
more frequent of rain drops, the interval time for Mote 2  to Mote 4
will change to 10 minutes of interval time to take reading. How can i
achieve this objective?
 
Can i use Motework in WIndow XP? How can i edit the binary files using
TinyOS? 
 
Can sir lead me to this in a step-by-step manner? i would appreciate it
a lot.

[Tinyos-help] Re Serial Baudrate

[Varun Jain]

By 'differently', I am referring to the code at /tools/tinyos/java/serial
à here we can see two files, namely NativeSerial_win32 AND 
NativeSerial_linux 

 

For Windows (Cygwin) machines, I believe it gets the code for Baudrate from In 
NativeSerial_win32 as below: 

 

int getBaudRate()

  {

int baud_rate = get_comm_state().BaudRate;

switch( baud_rate )

{

  case CBR_110:return 110;

  case CBR_300:return 300;

  case CBR_600:return 600;

  case CBR_1200:   return 1200;

  case CBR_2400:   return 2400;

  case CBR_4800:   return 4800;

  case CBR_9600:   return 9600;

  case CBR_14400:  return 14400;

  case CBR_19200:  return 19200;

  case CBR_38400:  return 38400;

  case CBR_56000:  return 56000;

  case CBR_57600:  return 57600;

  case CBR_115200: return 115200;

  case CBR_128000: return 128000;

  case CBR_256000: return 256000;

}

return baud_rate;

  }

 

AND IN Linux machines, we get Baudrates from  NativeSerial_linux file as below:

int baud_to_enum( int baud )

  {

switch( baud )

{

  case 0: return B0;

  case 50: return B50;

  case 75: return B75;

  case 110: return B110;

  case 134: return B134;

  case 150: return B150;

  case 200: return B200;

  case 300: return B300;

  case 600: return B600;

  case 1200: return B1200;

  case 1800: return B1800;

  case 2400: return B2400;

  case 4800: return B4800;

  case 9600: return B9600;

  case 19200: return B19200;

  case 38400: return B38400;

  case 57600: return B57600;

  case 115200: return B115200;

  case 230400: return B230400;

}

throw comm_port_error("baud_to_enum, bad baud rate");

  }

 

  int enum_to_baud( int baudenum )

  {

switch( baudenum )

{

  case B0: return 0;

  case B50: return 50;

  case B75: return 75;

  case B110: return 110;

  case B134: return 134;

  case B150: return 150;

  case B200: return 200;

  case B300: return 300;

  case B600: return 600;

  case B1200: return 1200;

  case B1800: return 1800;

  case B2400: return 2400;

  case B4800: return 4800;

  case B9600: return 9600;

  case B19200: return 19200;

  case B38400: return 38400;

  case B57600: return 57600;

  case B115200: return 115200;

  case B230400: return 230400;

}

throw comm_port_error("enum_to_baud, bad baud rate");

  }

 

All my discussion is based on my belief that when we use Java tools like 
"Listen, MsgReader, etc.", these files are used... if not then I am wrong  but 
if I am right, then we can see that after the baudrate of 115200bps, Linux 
machines can  have only 230400bps whereas Windows can have 128000 and 256000bps.

 

Secondly, my problem is that my platform has an atmel atmega128 processor, and 
all the platforms  having this processor can either have 19200 or 57600bps 
BECAUSE in the UART code for atmega128 located at 
/tos/chips/atm128/Atm128UartP.nc, it defines the following:

 

command error_t Init.init() {

if (PLATFORM_BAUDRATE == 19200UL)

  m_byte_time = 200; // 1 TMicor ~= 2.12 us, one byte = 417us ~= 200

else if (PLATFORM_BAUDRATE == 57600UL)

  m_byte_time = 68;  // 1 TMicor ~= 2.12 us, one byte = 138us ~= 65

 

 return SUCCESS;

}

 

So, I tried to add the code here and define the following:

 

else if (PLATFORM_BAUDRATE == 115200UL)

  m_byte_time = 33;  // 1 TMicor ~= 2.12 us, one byte = 69us ~= 33  -à 1 
byte takes 69 us so 69/2.12 gives 33 (POINT ME IF I AM WRONG)

else if (PLATFORM_BAUDRATE == 230400UL)

  m_byte_time = 17;  // 1 TMicor ~= 2.12 us, one byte = 35us ~= 17

else if (PLATFORM_BAUDRATE == 256000UL)

  m_byte_time = 15;  // 1 TMicor ~= 2.12 us, one byte = 31us ~= 15

 

 

I think either I have a fault in m_byte_time value because for 57600bps 
baudrate, it comes out 65, but a value of 68 is given in the basic code, I do 
not know why??

 

THIS IS WHY I ASKED if the higher baudrates are handled differently in Linux 
and Windows???

 

I need higher baudrate as the BaseStationw ill be receiving number of packets 
per second, so it needs to send it out of serial faster otherwise there will be 
a bottleneck.

 

I hope my question is more clearer now

 

Cheers,

I tried doing the 230400 baud rate as well on Cygwin, I think there is 
something either wrong in m_byte_time value that I am defining or something 
else I am missing, I am running Tinyos-2.0.2 under Cygwin, so I do not think I 
can go with the linux code.

I haven't ever seen the speeds that the Cygwin code uses.  I have seen what the 
Linux code uses, namely 57600, 115200, and 230400.

The Cygwin may work but it depends on what the underlying hardware supports.  
Given that Cygwin/Windows and Linux runs on the same hardware
it is very interesting the difference.

The easiest thing to do is try it.  I personally would go with the Linux code.

The telosb (msp430) h/w will support either mechanism by tweaking the divider 
and modulator registers.

All my discussion is based on my belief that when we use Java tools like 
"Listen, MsgReader, etc.", these files are used... if not then I am wrong  but 
if I am right, then we can see that after the baudrate of 115200bps, Linux 
machines can  have only 230400bps whereas Windows can have 128000 and 256000bps.

 

Secondly, my problem is that my platform has an atmel atmega128 processor, and 
all the platforms  having this processor can either have 19200 or 57600bps 
BECAUSE in the UART code for atmega128 located at 
/tos/chips/atm128/Atm128UartP.nc, it defines the following:

 

command error_t Init.init() {

if (PLATFORM_BAUDRATE == 19200UL)

  m_byte_time = 200; // 1 TMicor ~= 2.12 us, one byte = 417us ~= 200

else if (PLATFORM_BAUDRATE == 57600UL)

  m_byte_time = 68;  // 1 TMicor ~= 2.12 us, one byte = 138us ~= 65

 

 return SUCCESS;

}

 

So, I tried to add the code here and define the following:

 

else if (PLATFORM_BAUDRATE == 115200UL)

  m_byte_time = 33;  // 1 TMicor ~= 2.12 us, one byte = 69us ~= 33  -à 1 
byte takes 69 us so 69/2.12 gives 33 (POINT ME IF I AM WRONG)

else if (PLATFORM_BAUDRATE == 230400UL)

  m_byte_time = 17;  // 1 TMicor ~= 2.12 us, one byte = 35us ~= 17

else if (PLATFORM_BAUDRATE == 256000UL)

  m_byte_time = 15;  // 1 TMicor ~= 2.12 us, one byte = 31us ~= 15

 

 

I think either I have a fault in m_byte_time value because

[Tinyos-help] Counter32khzC component for mica platform

[m.khezri]

Hello
Counter32khzC is available for pxa27x processor and provides
LocalTime32khz interface.
Mica platform have Counter32khz32C but this component doesn't provide
localtime interface.
is it possible to make component like Counter32khzC for mica platform?

thank you.
