[Tinyos-help] RE: the TOS_MsgPtr var holds what
I don't understand very well what you mean when you say that "within which the receiveMsg() command is called...", but I think I can perhaps help you a little bit.When you want to receive something you just need to use the interface ReceiveMsg (GenericComm provides this interface, so just wire your component to it). Interface ReceiveMsg signals the event ReceiveMsg.receive() when a packet comes. It will give you a TOS_MsgPtr. As you have well guessed, if MsgPtr is a TOS_MsgPtr variable, MsgPtr-data contains the useful data. If you useful data is of type DataType, just do this:DataType* pointerToUsefulData;pointerToUsefulData = (DataType*) MsgPtr-data;Now you can access all the fields in your data using variable pointerToUsefulData. For instance, if DataType has field named tempValue, you just do this to access it:where_you_want_to_save_the_received_data=pointerToUsefulData-tempValue;Anyway, you have examples about this in the tinyos tutorial [1], and more documentation in the file ReceiveMsg.nc in tinyos-1.x/tos/interfaces.[1]: http://www.tinyos.net/tinyos-1.x/doc/tutorial/index.htmlprimalfear 69 [EMAIL PROTECTED] escribió: hello thanku very much for ur reply.. buti have another doubt..what i am doing is receiving the packets from the radio using the function TOS_MsgPtr receive(TOS_MsgPtr received) within which the receiveMsg() command is called ..till here it is fine but my doubt is1. the received parameter variable in the func holds whatdoes it holds the starting value of the packet or what .. 2. if i want to view only the data coming from the radio other than the address and the length etc.so can i view this databy writing as received-data[i]; or something else. 3. in my code i called for HPLUART.put(received-data[i]) within a for loop.this is giving only the first two values of the data which i want to view..but i want all data,length of the data,crc etc.. can u help me out with these... with regards, LLama Gratis a cualquier PC del Mundo.Llamadas a fijos y móviles desde 1 céntimo por minuto.http://es.voice.yahoo.com___ Tinyos-help mailing list Tinyos-help@Millennium.Berkeley.EDU https://mail.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help

[Tinyos-help] ADC switch channel
Hi all, I have a 3-axis accelerometer mount on tmote sky. Every axis (x,y and z) is connected with a different pin of the expansion connector and I want to sample a channel and switch to the next (from x to y and from y to z) cyclical. I must do it at 6000Hz but I see that the ADC time for switch from a channel to another is 10ms(!) so I can go at maximum rate of 100Hz.. I can't believe that an ADC that can sample at 200KHz take 10ms for switching on channels.. How can I do to improve this frequency? I try to look on MSP430 user guide and I see there is a register called ADC12MCTLx (ADC12 Conversion Memory Control Registers) where I can switch the input channel setting INCHx. Do this mean I must use assembly code? If yes, how can I do this? Thanks in advance. Andrea. __ Do You Yahoo!? Poco spazio e tanto spam? Yahoo!

Re: [Tinyos-help] Sleep mode,micaz,tinyos-1.x
You can use timers with HPLPowerManagement, at least with the Mica2/Dot/Z motes. The only problem I have had is that occasionally they get lost, especially if the timer interval is short. My solution has been to always use repeating timers rather than one-shot timers. That way, if you lose one event, the timer will eventually fire again. Once I made that change and wrote my code with the assumption that my 1 second timer might fire in 2 seconds, then it all worked fine.

Re: [Tinyos-help] FTSP on Tmotes
I would be very hesitant to say anything is an absolute guarantee. Brano from Vanderbilt identified a note in the MSP430 User's Guide regarding potentially corrupt readings of a timer based on a asynchronous clock source. This seemed like the likely source of errors in corrupt time values. The user's guide indicated the workaround is to take a majority vote of the timer readings to determine a valid reading. With that fix and without a deeper analysis of the issue, it seems like there is still an infinitesimal chance getting of a corrupt reading, though a corrupt reading is at least significantly less likely than before. Asserting anything stronger than that would require a longer study which I have not performed.

Re: [Tinyos-help] how interrupts are handled in tinyos
There was just a huge discussion of interrupts and async functions on this list, perhaps even this month. This is a good search start: http://www.moteiv.com/community/TinyOS_Information If you want the actual TOS code that wraps ints you'll have to go search _every_ source file, just like the rest of us. Sorry, I don't know where it is...I would start in the platform/avrmote (for mica's anyway) directory and work back through all the includes... The phrasing of your question leads me to wonder if you are asking about the basics of interrupt handling however, if that is the case the micro-controller spec-book is probably the best place to look. On the atmega128 the RETI instruction is used to...yup... RETurn from Interrupt.

[Tinyos-help] Question about tasks in Tinyos 1.x
Dr. Levis:
If a command has the following code
command result_t A.p(){
...
post TaskB();
...
}
If some module call A.p(), the execution sequence is : first A.p() is
put into the task queue and runs to
completion, and then TaskB will be executed until a later time. And the
return value of A.p() is whether TaskB be put into the task queue.
So command and event function is also two kinds of tasks. But a C-like
function such as
void f(){
}
is not a task and will return immediately.
Is my understanding right? Please correct me. Thanks.
Regards,

[Tinyos-help] Problems Compiling on Fedora Core 4 Related to offsetof()
Dear TinyOSers, I am trying to compile TinyOS 1.1.0 on Fedora Core 4, and ran into a problem that many others have had relating to offsetof(). When I try to compile, I get 4 error messages of the sort /opt/tinyos-1.x/tos/types/AM.h:157: parse error before `struct' As I understand the problem, the offsetof() macro has been changed since Linux kernel 2.6.9. Instead of using a generic method, it is now replaced by a compiler specific function __builtin_offsetof() which is not recognitized by nesc. I have found the patch located in the message http://mail.millennium.berkeley.edu/pipermail/tinyos-help/2005-September/012275.html But do not know how or where to install the patch. If someone could give further instructions for installing this patch, replacing my old version of gcc, or any other way to solve this problem, I would be ever so appreciative.

Re: [Tinyos-help] Problems Compiling on Fedora Core 4 Related to offsetof()
Patch files are applied thusly: patch -p0 tinyos.patch You need to be in the top level directory and it assumes the patch was made there. Otherwise you might need to alter the -p option. I seem to recall that patch was a -p1 but I don't recall. But you might be able to use a newer version of nesc which doesn't need the patch. The latest and greatest works for me for my TinyOS 1.x work. But I can't comment on 1.1.10.

RE: [Tinyos-help] make mica2 (error).
That is an installation error. It means that it cannot find the nesC for TinyOS compiler called ncc. What version are you running? What system are you running on? Linux or Cygwin? Have you installed from source, rpms or cvs? If you provide this information it may help. You may also want to go through the installation procedures carefully.

RE: [Tinyos-help] Serial In-Programming or Ethernet In-programming
I don't know anything about the MIB600, you might have to have a look on the crossbow website (www.xbow.com). For the MIB510 you need to type something like: make micaz install mib510,device Where device is the serial port, eg /dev/ttyS0 for COM1, /dev/ttyS1 for COM2 (note the S is uppercase!)

Re: [Tinyos-help] Question about tasks in Tinyos 1.x
Hi, Cory,
Thank you for you reply.
But on the mailing list, most of them deal with interrupt and event
handler. When I concern about is the command function and task.
If as you said command function is like C function and returns
immediately, why does nesC need asyn command? Asynchrous command
function executes immediately and preempt tasks.
Is command function without asyn like task will be deferred for some
time. For example,
(1)Non asyn command function
In component A, it call B.process(), which isn't defiedn as a asyn
command. Then B. process() will be put into the task queue and executed
later.
(2) asyn command function
Component A call B.process(), which is asyn command. Then B.process()
execute immediately and preempt other tasks in the task queue.
So my conclusion is that command function without asyn is like task,
insead of C-function.

put into the task queue and runs to

return value of A.p() is whether TaskB be put into the task queue.
So command and event function is also two kinds of tasks. But a C-like
function such as
void f(){

is not a task and will return immediately.
Is my understanding right? Please correct me. Thanks.

Re: [Tinyos-help] FTSP on Tmotes
Hi Cory, I was continuing my experiment and I do observe that there are bogus timestamps despite the fix and as you mention, they are less frequent than before. I understand that the problem arises because of trying to read the timer (based on an async clock source) when it is running.TimerM component ultimately uses Timer B of the MSP430. Is it possible to use Timer A and provide a new LocalTime.read exclusively for the purpose of FTSP ? Is Timer A used in any important component ? ( I notice that it is used by LocalTimeMicroC/some ADC component - can this be done away with if I do not use it in my application ?) If I can use Timer A exclusively, will the following steps work ? : 1. Start timer A in continuous mode using TimerA.setMode(). 2. Set the mode to halted using TimerA.setMode() 3. Read the TAR register using TimerA.read() 4. Restart timer A in continuous mode using TimerA.setMode() Thanks and Regards,Harish On 9/26/06, Cory Sharp [EMAIL PROTECTED] wrote: I would be very hesitant to say anything is an absolute guarantee. Brano from Vanderbilt identified a note in the MSP430 User's Guide regarding potentially corrupt readings of a timer based on a asynchronous clock source. This seemed like the likely source of errors in corrupt time values. The user's guide indicated the workaround is to take a majority vote of the timer readings to determine a valid reading. With that fix and without a deeper analysis of the issue, it seems like there is still an infinitesimal chance getting of a corrupt reading, though a corrupt reading is at least significantly less likely than before. Asserting anything stronger than that would require a longer study which I have not performed.

In this paper, two problems have been mentioned with regards to FTSP. 1) The problem with the clock driver (apparently seen only on Tmotes) that seems to return bogus timestamps. 2) FTSP does not check validity of time sync messages.The first seems to have been fixed in the change to TimerM.nc in /tos/platform/msp430done in February 2006. Does this guarantee that there will be no bogus timestamps anymore ?Given the fact that this fix has been done, can we assume that the time filtering/timerectification approach mentioned in the paper is not required anymore ?

If yes, what was the accuracy obtained ? Is it of the order of micro-seconds ? I was trying it but I cannot see better than millisecond accuracy.
