[Tinyos-help] Re: regarding the TosMsgptr and TosMsg
Perhaps what you want is TOSBase (it's an application included with TinyOS). You install it on a mote and this mote will act as a bridge between the radio and the serial port (will send to the serial port everything that hears from the radio and will send to the radio any packet received by the serial port). You program one mote with this application and use 'java net.tinyos.tools.Listen' to listen to all packets received through the radio or 'java net.tinyos.mcenter.MessageCenter' (see tinyos-1.x/doc/mcenter.html for more information). Of course, if you just have one mote you won't see anything, you need to programa one or more motes with your program and another one with TOSBase to see ion your computer (using the java programs) what the other motes and sending through the radio or to inject new packets with 'java net.tinyos.mcenter.MessageCenter' or another application.TOS_Msg is just an structure. You can see it at tinyos-1.x/tos/types/AM.h. If you want to access its fields you just do the next:TOS_Msg your_msg;TOS_Msg* your_msgPtr;your_msg.addr = destination_address;your_msgPtr-data = "" (accessing with pointer)If you want to build packets in the PC and sent them to motes you can use the tool mig [1]. But you must declare you message structures in an .h file with a specific format.

RE: [Tinyos-help] repeating tests,no free memory
I'm using not so much RAM, at compile time is around 1700 bytes (it depends on
the different versions of my program).
But now, after other tests, i see that when the motes enter in the
reading-from-flash phase, something happens and some of them break down. They
are not more able to work.And only after a reading phase.
May be the batteries? i know about the 70mA of current, but if i use
rechangeable batteries, so 1.3 V, are there problems?i can measure only voltage
by a voltmetre.
I really don't know how to understand what's going on in the reading phase to
let some motes to break down in this way.
One problem may be is about the parameters i need when the reading phase is
done: i need the same parameters i use when i posted the task.So the global
parameters buf_flash,State,mess,flashAddr,
flashLen,flashBuffer are probably different when the readDone event fires up
from the ones used posting the task.But only when the reading is done i can use
that buffer and so i can execute my program..so for example sending
packets,math operations,etc..
Buffer *flashBuffer,*buffer,*ibuf,*ibuff;
Buf_flash *Head,*buf_flash;
Datagram *mess,*datagram;
uint8_t State;
task void readFlash(){
if (!call FlashBridge.read(flashAddr,flashBuffer,flashLen)){
post readFlash();}
return;
}
void readInToFlash(uint8_t s,Buf_flash *buf,Datagram *message,Buffer
*buffer_r,uint32_t addr, uint32_t len){
buf_flash=buf;
State=s;
mess=message;
flashAddr=addr;
flashLen=len;
flashBuffer=buffer_r;
post readFlash();
return;
}
event void FlashBridge.readDone(uint32_t addr, void *buf, uint32_t len,
result_t result){
if (result){
//operations where i need to use the same global variables declared in the
task!for now i'm using normally mess,State,etc..but i think are different from
the same one before posting the task.
//for example if i use
//if(mess-data==...).
//i think it is not the same mess written before post readFlash()...
else
post readFlash();
return;

Subject: RE: [Tinyos-help] repeating tests,no free memory
How much RAM is your program consuming at compile time? The MicaZ is
notorious for running out of RAM just when you need it because it only
has
4kB. If your global memory usage is already quite a bit (3kB maybe?
maybe
more? maybe less?) and you throw a bunch of stuff on the stack, your
mote
will crash in a seemingly random fashion, depending on what's going on.
I've had apps before that used around 3kB of RAM when the program is
compiled, and then crashed awhile later because the stack overflowed.
If the task queue is full (and it's in global memory btw, so simply
posting
tasks shouldn't cause a stack overflow) then when you post a task, the
post
will return FAIL. It could also be that your app is posting a task and
expecting it to run before continuing on, and that task never actually
got
posted. I've personally never had that problem before, even with
running a
full file system on top of flash bridge with the radio transmitting and
receiving.

Subject: RE: [Tinyos-help] repeating tests,no free memory
Dear all,
i tried to use TinyAlloc interface but the results are really
similar.
So this is not a problem of the calloc function.
But i start thinking the problem is in the stack. If i post too many
tasks,
can the mote crash?
The problem is that i have to use tasks to handle the FlashBridge
interface
in order to use properly the reading and writing phase on Flash-RAM.
And i'm
also using a task for the sending interface (own mote messages) and for
the
forwarding one (messages from other motes), all synchronized by timers.
So if i use micaz motes, tinyos-1.x, can it be a problem?
Because i'm freeing all the times the memory i allocate, but if i
repeat the
experiments with the motes on, in the second round or in the third one,
one
(or more)of these breaks down. It seems quite randomly.
Hoping in any kind of help,
cheers

On Sep 18, 2006, at 7:09 AM, KANG HUI wrote: The Tmote datasheet gives how lqi is calculated. Well, not really. Here's a more detailed explanation Oyvind Janbu, who was the program manager for the CC420 chip, gave me: - First of all, regarding the correlation value provided in the RXFIFO together with the received frame: Like you know, the 2.4 GHz physical layer of the 15.4 standard uses 32 chips to represent 4 information bits. Each of the 16 possible symbols is represented by a predefined 32 chip sequence. The receiver is based on correlating the received chip sequence against all of the 16 possible symbols. However, the receiver never does _chip_ decision. Each chip is represented by a soft decision chip (more like a probability of being either 0 or 1) which in turn is used to correlate against the known chip sequences. For each symbol following the SFD, the receiver will select the one with the highest correlation value. The correlation value in the RXFIFO is the sum of the 8 first correlation values for the selected symbols following the SFD, represented by a 7 bit unsigned integer value. My point with respect to the paper is that the receiver doesn't do chip decision at all, hence there is no actual chip errors. This is of course implementation specific, and may be different on another transceiver. The soft decision chips are also the reason why the correlation value doesn't go all the way to 127 (even if its a 7 bit value). This is due to bandwidht limitations in both the transmitter and receiver, that make the soft decision chips stay away from the ideal values. However, this doesn't affect the performance of the receiver, it's only a representation issue. - Phil ___ Tinyos-help mailing list Tinyos-help@Millennium.Berkeley.EDU https://mail.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help

Re: [Tinyos-help] Watchdog for tmote
It is easy to use the watchdog timer in the MSP430, and using it is fairly application specific, which are primary reasons there is no component for it. Here are some tips:1) Read Chapter 10 Watchdog Timer in the MSP430 x1xx User's Guide from TI 2) MSPGCC defines some helper macros in common.h (which is indirectly included in all TinyOS MSP430 builds). Find it at /opt/msp430/msp430/include/msp430/common.h. See for instance WDT_ARST_1000 which configures the watchdog timer to fire after about 1000ms based on a 32kHz ACLK. 3) For a concrete example, see KrakenWatchdogM.nc in tinyos-1.x/contrib/nestfe/nesc/sensorboard/trio/. You will need to check that out from CVS, a packaged TinyOS distribution will not have it. For instance, the code is constructed so that this line of code is periodically called things are working correctly: WDTCTL = WDT_ARST_1000; The pieces tested here are the Timer system (explicitly) and task execution (implicitly). If either of those catastrophically fail, the system resets within a few seconds.- Cory On 9/18/06, Pablo Gil Montaño [EMAIL PROTECTED] wrote: From what I understand, I don't think so, because if the system enters an infinite loop or somtehing it will prevent both timers from firing and nobody will reset the device.KANG HUI [EMAIL PROTECTED] escribió: Hi,is that possible you can use two or more timer so that one timer can be used as the watchdog?On Mon, 18 Sep 2006, [iso-8859-1] Pablo Gil Montaño wrote: Hello.

Re: [Tinyos-help] External sensor reading
Cepni,It will not be possible for you to sample at 30kHz across two channels and transmit the data in real-time. You will have to sample sensors to some form of flash memory. The motes have a 1mB flash chip, but this will fill up very fast with the sampling rate you are needing. The 1mB flash chip will be capable of storing only about 8.5sec worth of your data. It will probablyalso be difficult to efficient write code transfer the data across the SPI bus to the flash chip fast enough, since the system clock is just 4MHz. The reason that this is not possible for real-time sampling is that the network cannot handle throughput rates that high. The maximum theoretical data rate of the radio is 250kbps. ADC samples are 2bytes in size, so:30,000 samples/channel * 2 channels * 2 bytes/sample *8 bits/byte = 960kbpsThis is almost 4x the rate that can be pushed across the radio.Someone else on the list can correct me if I am wrong, but I thought you should know some of the restrictions that you are facing trying to uses the motes to sample that fast.Matt[EMAIL PROTECTED] wrote: -To: tinyos-help@Millennium.Berkeley.EDUFrom: "Gurkan Cepni" [EMAIL PROTECTED]Sent by: [EMAIL PROTECTED]Date: 09/18/2006 02:19PMSubject: [Tinyos-help] External sensor readingHello everyone, I am trying to use Moteiv- tmote telos-b unit to sample two signals using the external pins available on the unit.

If you can use ListenRaw to get the actual message bytes you may be able to hand disassemble them and figure it out.

On Monday 18 September 2006 01:11 pm, Gurkan Cepni wrote: Actually, I am not planning to sample the signals continously. That's ok for me to sample for just 2 secs. (using 30ksps sampling rate: I want to sample it fast so that the environment will not change much) I wrote a test program on a Telos-like platform (MSP430, 4MHz) that sampled 3 channels at 26kSa/sec (aggregate rate of 78kSa/sec), performing a simple sum-of-squares calculation on each group of three samples and saving the largest vector. The program did nothing else and was definitely maxing out the processing power of the MSP430 (it was using the coprocessor to calculate the squares). This code later went into a sampling application where it was throttled back to 10kSa/sec (30kSa/sec aggregate), sampling very infrequently and only for 500ms at a time. IOW, you can probably hit 30kSa/sec for 2 channels if you can figure out how to handle the amount of data being generated. Based on your analysis, 2 secs. of data is 960kbps*2sec=1920 kb. This can be easily stored on the memory and be transferred to base station (it is not critical to how fast the mote transfers data to base station.). Actually, 1920kb is nearly 2 megabits. It would fit in flash, but I'm not sure if the TelosB is fast enough as a whole to drive the flash fast enough. If storing all the raw data, 2 second sample may still be too big to reliably handle. In short, I will push a button on the remote mote, the mote will sample 2 external signals (with 30ksps) for 2 secs, store data on the memory, send it to base-station, then laptop, then save it on the computer. The next time I push the button for the second recording can be 20 sec.s or more later, no problem. Can the mote do some processing of the sample data before sending it to the computer? If you're looking for a certain kind of event, perhaps all or part of the processing required to characterize that event could run on the mote and reduce the size of the data set considerably. ___ Tinyos-help mailing list Tinyos-help@Millennium.Berkeley.EDU https://mail.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help

3.3-3.6 volts just to allow for some voltage sag. The crash happens so fast

I really don't know how to understand what's going on in the reading phase

flashLen,flashBuffer are probably different when the readDone event fires up
from the ones used posting the task.But only when the reading is done i can

How much RAM is your program consuming at compile time? The MicaZ
is
notorious for running out of RAM just when you need it because it
only has
4kB. If your global memory usage is already quite a bit (3kB maybe?
maybe
more? maybe less?) and you throw a bunch of stuff on the stack, your
mote
will crash in a seemingly random fashion, depending on what's going
on.
I've had apps before that used around 3kB of RAM when the program is
compiled, and then crashed awhile later because the stack
overflowed.
If the task queue is full (and it's in global memory btw, so simply
posting
tasks shouldn't cause a stack overflow) then when you post a task,
the post
will return FAIL. It could also be that your app is posting a task
and
expecting it to run before continuing on, and that task never
actually got
posted. I've personally never had that problem before, even with
running a
full file system on top of flash bridge with the radio transmitting
and
receiving.

[Tinyos-help] RE: Blackbook5: dataLength, minimumSize for dictionary files
Hi Manu, In Blackbook5, what does BDictionary.getDataLength return? .. what should minimumSize include? First, are you referring to the BFileDir.getDataLength(char *filename) command, being run on a Dictionary file? Dictionary files have special properties to them that allow them to be updated indefinitely. The way it works is when you first open a Dictionary file, you must specify the minimum size. On the flash, Blackbook will reserve *at least* that minimum size to store data - but if you want the background information on that, the actual size on flash will extend to the next page boundary. This can make your actual file size up to 255 bytes larger than you requested. Better a file be made a few bytes too big than too small. After you have opened a Dictionary file for the first time, its footprint on flash will remain constant throughout its lifetime. The dictionary file itself will physically move around to various locations on flash as it fills up and removes invalid keys throughout its lifetime, but the valid (undeletable) footprint on flash will always stay the same. Because flash can't actually delete data very easily, is better to leave old data written to flash and just ignore it. That means that as you delete or update existing keys in your Dictionary file, the amount of data in that Dictionary file is growing, not shrinking or changing. There comes a point where the amount of data (invalid + valid data) in the Dictionary file fills up to the size you requested when you first created the file. At that point, the Dictionary file will physically move to another location on flash and copy all the previous valid key-values over, leaving all the old key-value pairs behind (to be deleted by the garbage collector when the time is right). So... if you call getDataLength(..) on your dictionary file, you'll see the size is changing all over the place as you add or update keys - or maybe it changes only after you've closed and opened the file again. However it does it, a better indicator of Dictionary file size is getReservedLength(..), which tells you the dictionary file's footprint on flash. If you were to copy a complete dictionary file from flash to your computer, you'd want to copy its entire footprint, which is getReservedLength(..). The reserved length should remain constant throughout the file's lifetime, as I said. But it could be much bigger than the amount of data actually written to the dictionary file. Also, when you call Bdictionary.open, you get an opened() event with uint32_t totalSize, uint32_t remainingBytes. These two variables give you a snapshot of the state of the Dictionary file, but it's only valid at the time you open the Dictionary file. The amount of actual data in the Dictionary file should be (totalSize - remainingBytes). Back to the minimumSize parameter on open... Because the Dictionary file's footprint remains constant throughout its lifetime, that means that the minimumSize parameter in Bdictionary.open(..) gets completely ignored if it's not the first time you've opened that specific Dictionary file. The minimumSize parameter is only accessed the first time you open a Dictionary file. The larger you make the minimumSize value when you call Bdictionary.open for the first time, then A) you'll be able to store more and larger key-value pairs in your file, and B) it's going to take more time and energy to insert and retrieve key-value pairs as your Dictionary file fills up. And yes, the only real way to count the number of keys is to actually traverse the key list like you mentioned. If Blackbook provided that functionality itself, that's exactly what it would do. And since that's not needed in all applications, it's better to save ROM space for the apps that don't need it and only implement it at a higher level above Blackbook for the apps that do need it. I hope that clears things up and I also hope Blackbook is working out for you. Let me know if you have any more questions -David -Original Message- From: Manu Bansal [mailto:[EMAIL PROTECTED] Sent: Monday, September 18, 2006 11:50 AM To: [EMAIL PROTECTED] Cc: [EMAIL PROTECTED] Subject: Blackbook5: dataLength, minimumSize for dictionary files Dear Mr. Moss, I am an undergraduate student at Indian Institute of Technology Kanpur (IIT Kanpur), working on a sensor network project and using Blackbook5. There's a question to which I couldn't find an answer in the included pdf or the interface inline comments. I couldn't get any help from the tinyos-help list either, hence a personal mail. In Blackbook5, what does BDictionary.getDataLength return? Is it the length of data inserted as values, or keys and values both, or other? And similarly, what should minimumSize include? For regular files, the semantics is clear, but I'm not sure about dictionary files, and getDataLength doesn't return the expected value. For 5 key-value pairs each having value 12B long, the returned
