[Tinyos-help] interfacing devices with uart....
Hi, I saw a post/query posted earlier at: https://www.millennium.berkeley.edu/pipermail/tinyos-2-commits/2007-June /005830.html I could not find the answer to this, does someone knows how to do achieve this in TINYOS-2.x as I need to something similar, i.e. attach devices on the UART so I just need to send raw bytes on the UART??? I am using Chipcon motes (similar to micaz) and Cygwin.

[Tinyos-help] making a loop sleep.
Hi all, I am using TinyOS 2.x and using Tossim to test my results I was wondering if there is a command that may allow me to make a loop sleep so I can send something over the radio to another mote? What I have is a loop that keeps running, then within the loop, I may choose to send a message over the radio to another mote, the problem is I don't want to break out of the loop, what I would like to do is to send the message then continue the loop from where I stopped last! What is actually happening is, the loop keeps running till the end, and then sends the message. I would be thankful for any hints Thank you. ___ Tinyos-help mailing list Tinyos-help@millennium.berkeley.edu https://www.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help
Re: [Tinyos-help] help please : turn off mote packet loss rate ?

[Tinyos-help] obtain RSSI value
Hello everyone!! I have some questions. In general, there is two method to obtain RSS value. One of them is using strength parameter of the message, but it just is a value of a intended message. I want to know all of things, which are intended signal as well as interference signals. So, I'd like to read RSSI register. But, I think its value is not correct. First question is when RSSI register value changes. Second, how to read all information(ACK signals + interference signals) on the sender.

Re: [Tinyos-help] making a loop sleep.
Hi! I think, I had one similar issue: https://www.millennium.berkeley.edu/pipermail/tinyos-help/2008-June/034400.html I've used printf in a loop and there was no action at all! Although my question was not answered, I'm thinking meanwhile that some functions in TinyOS being scheduled, so if your calling function doesn't finish, the scheduler can't switch to run your send() or my printf(). So one have to release the control flow to allow other called functions to get running. So you could remove the loop and in sendDone start the function that calls send() again. I can assume it is better than to call send() without to be sure sendDone was signaled. It's a pity that the compiler can't check whether the called function can get finish without the calling part have to release the control flow or not. Or there are any parameters I can pass to? Can anyone point to the description, how one can distinguish between these 2 types of functions? Andrey P.S. I had a couple of days ago bad experience with compiler checks. My program in C for atmega64 didn't work. After some time I've figured out what was wrong. I've forgotten to declare a function to handle a timer interrupt. There were no compiler warnings/errors, I'm missing a such critical function!..

[Tinyos-help] error using UartStream......
Hi all, For all the ones that wants to use uart communication in tmote, some things have to be taken in consideration: -What uart do you want to use, UART1 is the uart associated with USB communication so this isn't the one you want to use probably. UART0 is the one exported in the expansion pin connector, but is also shared as a SPI bus with stm25p flash and cc2420 radio chips. -What type of communication you intend to establish, i.e just send bytes to uart, just receive, receive in response to a sent command, or send and receive in a full duplex manner were the receive is not correlated to the send event. Taken this things into account one cant do the following: -In the case that you use UART1 there is no problem at all, I mean you remove the usb or what ever but you have access to the uart, there is no conflict chip intervening in this uart. For the case you use UART0, the most common case: -For just sending: - you have to request the resource - when granted the resource send your bytes. - when send done release the resource. -For just receive or send and receive asynchronously do the same: - request the resource at boot - own the resource for ever. YOU WON'T BE ABLE TO USE FLASH NOR RADIO -For receive that is correlated in time with the send: - request the resource. - when granted the resource send your bytes. - when send done done nothing. - wait until the receive is done. - then release resource. In this last configuration you would be able to use flash and radio. For Varun: In your case you have some compile errors in using the interface because you don't wire all the events the interface provides. I almost sure PlatformSerialC and TelosSerial in particular modules are related to UART1 means USB at 115200 and other parameter set, where are you connecting your leds?.I had posted other mail response in July 2008 were I copy/paste example code on how to do this, in particular the case were ones request the resource for ever, you only have to add the release of the resource when you no longer need it. mail me if isn't clear enough, or you have another question. to do this add my mail in the cc, so it would be in the mailing list for others to get an answer, just like i did in this mail. -Bill ___ Tinyos-help mailing list Tinyos-help@millennium.berkeley.edu https://www.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help

Re: [Tinyos-help] Limited number of timers?
Thank you Eric for the detailed explanation! I did not use
VirtualizeTimerC directly at first. But I tried it because I had some
strange problems with a timer and thought the reason could be that I
use to much timers at a time. Now I know that it has to be another
reason. By now I have found a workaround that works in my case (

Hi,
I am not sure if I got it right.
Close.
Does it mean that I do not have to
care about virtual timers because they will be used automatically by
TinyOS?
Yes it means tinyos will handle the virtualization for you.
If this is the case then the following code would create virtual
timers based on another virtual timer. Right?
Not quite. You don't want to reference VirtualizeTimerC directly. You
want to use TimerTMilli and let the platform wiring handle the
virtualization
for you.
Take a look at tinyos-2.x/apps/tutorials/BlinkTask/*
You'll see something like:
BlinkTaskAppC.nc:
configuration BlinkTaskAppC
{
}
implementation
{
components MainC, BlinkTaskC, LedsC;
components new TimerMilliC() as Timer0;
BlinkTaskC - MainC.Boot;
BlinkTaskC.Timer0 - Timer0;
BlinkTaskC.Leds - LedsC;
}
And in BlinkTaskC.nc:
module BlinkTaskC
{
uses interface TimerTMilli as Timer0;
uses interface Leds;
uses interface Boot;
}
implementation
{
task void toggle()
{
call Leds.led0Toggle();
}
event void Boot.booted()
{
call Timer0.startPeriodic( 1000 );
}
event void Timer0.fired()
{
post toggle();
}
}
So if you wanted to use three timers you would do something like:
BlinkTaskC.nc (app)
uses interface TimerTMilli as Timer0;
uses interface TimerTMilli as Timer1;
uses interface TimerTMilli as Timer2;
And in the wiring:
components new TimerMilliC() as Timer0;
components new TimerMilliC() as Timer1;
components new TimerMilliC() as Timer2;
BlinkTaskC.Timer0 - Timer0;
BlinkTaskC.Timer1 - Timer1;
BlinkTaskC.Timer2 - Timer2;
Where this wires into the underlying layers is via the system component
TimerMilliC which eventually
causes VirtualizeTimerC to hook up to the underlying platform timer
hardware.
Take a look at:
tinyos-2.x/tos/system/TimerMilliC.nc
tinyos-2.x/tos/system/TimerMilliP.nc
tinyos-2.x/tos/chips/msp430/timer/HilTimerMilliC.nc (I build for telosb)
tinyos-2.x/tos/chips/msp430/timer/AlarmMilli32C.nc
etc.
To follow what is happening, build BlinkTask as follows:
cd tinyos-2.x/apps/tutorials/BlinkTask
make verbose telosb
It will show which files are being pulled in.
eric
make
components new TimerMilliC() as BaseTimer;
components new VirtualizeTimerC(TMilli, 5);
VirtualizeTimerC.TimerFrom - BaseTimer.Timer;
DbgMessengerP.Timer0 - VirtualizeTimerC.Timer[0];
DbgMessengerP.Timer1 - VirtualizeTimerC.Timer[1];
[...]
Thank you,
Nicola

Re: [Tinyos-help] error using UartStream......
I can't comment on the wiring as I try to remain as aloof as
possible from nesc syntax, I would try to find some other usage
examples and emulate them.
However you do need to implement all the events in an interface.
Just make stubs for the ones you don't plan to use.

Hi,
I am trying to send raw bytes of data on the UART to operate a serial
7-segment LED screen connected to the remote nodes(as the screen accepts
commands in terms of hex bytes to display the data). For this I am using
the UartStream interface as follows:
---In the application module’s
implementation---
call UartStream.send(buf, sizeof(buf));
event void UartStream.sendDone(uint8_t* buffer, uint16_t len, error_t ok) {
if (ok == SUCCESS) {
call Leds.led1Toggle();
}
}
---and the wiring looks like as
follows-
components PlatformSerialC;
AntiTheftC.UartStream - PlatformSerialC;
But I am getting errors as follows:
In component `AntiTheftC':
AntiTheftC.nc:236: `UartStream.sendDone': async mismatch with declaration
/opt/tinyos-2.x/tos/interfaces/UartStream.nc:57: previous declaration of `Ua
rtStream.sendDone'
AntiTheftC.nc:54: `UartStream.receivedByte' not implemented
AntiTheftC.nc:54: `UartStream.receiveDone' not implemented
make: *** [exe0] Error 1
Can anyone suggest what is the problem or how can it be fixed? What I
understand from UartStream interface is either we can send or receive
multiple bytes on UART, for sending don’t we just need to send and
senddone OR do we also need to use other commands in this interface
JUST FOR SENDING, I do not want to receive back anything.
Is there any other interface to do this task ???

Re: [Tinyos-help] Doing Re-transmissions
Lets keep this on the help list
As for loop 1, if you enable ACKs in the protocol they are handled
in the lower levels and sendDone() is not called until the message
is ACKed or times out. Search this list for many ACK explanations,
and references to my robocode that makes extensive use of ACKs.
As for message copy. You need a message buffer that lasts at least
until all the sends are Done. If you can keep track of the buffer
from the original message then you can just re-use it, otherwise
you should copy it before trying to send again because the send
operation will last longer than the scope of the function call,
task or not...

I'd bet that the message buffer gets reused or erased before your

send directly from the done, since done is in an event
context which is sometimes tantamount to an interrupt, perhaps
try copying the message and posting a task to resend?
Another possibility is that you are walking over the normal
send process. You should check the result of the second send
to see if it's giving you an error. And you may need to put
in some condition variable to block simultaneous sends.

First I'm not sure what problem you are trying to solve. The description you give above sounds complicated. If I understand correctly from the event handler for send.senddone you want to check to see if a message was received and do something else. Is that correct? If so it seems simpler to let the different handlers handler their one thing. Just an aside. events are signaled from another module and as such are pieces of static code. As such there isn't a way to detect an event in another event. That said your alternative sounds like it might work but it depends on what kind of events, async or not, are being used. And as soon as you start mixing async stuff and wanting it to interact with a task level event things get complicated quickly. eric An alternative to this may be using conditional variables.I declare a global variable flag as false.Keep performing some task in senddone() event.when a packet is received,receive event generated will set the flag as true, then I will stop doing task in senddone() event.Will this work?

Re: [Tinyos-help] Doing Re-transmissions
I don't know an exact message delay figure. There's some software
overhead, and then the MAC protocol which may backoff a random
time to avoid collisions. There's also some indication that there
should be a few milli-sec delay before retrying a message -- see
recent posts and my message reliability reports -- but that might
be receiver related.

I've made the file called .bashrc at /cygdrive/c/Documents and Settings/jfell and placed in it the following shell script: export CLASSPATH=`cygpath -w $TOSROOT/support/sdk/java/tinyos.jar` export CLASSPATH=$CLASSPATH;. TOSROOT=/opt/tinyos-2.x TOSDIR=$TOSROOT/tos CLASSPATH=C:\tinyos\cygwin\opt\tinyos-2.x\support\sdk\java\tinyos.jar MAKERULES=$TOSROOT/support/make/Makerules PATH=/opt/msp430/bin:$PATH However, now I am getting this error when I launch the Cygwin Bash Shell: bash: /usr/local/bin/locate-jre: No such file or directory This error does not occur, if I run the same script manually from a file I made called go.sh. Any thoughts?

Is there a way to get Cygwin to auto-launch a shell script when the Cygwin Bash Shell launches? You can put shell commands in the file .bashrc in your home directory.

In my T1 system that's in tools/scripts/locate-jre are you sure it's in the /usr/local/bin directory? Jim Fell wrote: Hello Nicola, Thanks for the tip!

2008/7/30 Jim Fell [EMAIL PROTECTED]: Hello Nicola, Thanks for the tip! I've made the file called .bashrc at /cygdrive/c/Documents and Settings/jfell and placed in it the following shell script: You should have a file named .bashrc in your cygwin home directory not in the windows home directory ;) This should be something like /home/jfell from your cygwin shell. Try a ls -a and you should see it. However, now I am getting this error when I launch the Cygwin Bash Shell: bash: /usr/local/bin/locate-jre: No such file or directory I do not think that this error has anything to do with the file in your windows home directory.
