hi all
i am having two doubts...
---at first...
i hav successfully compiled and installed the modified the Delta application for external ADC signal...sampling time period is 10ms..
when i hav given a sinusoidal signal of 0.5V with an offset of 0.75V at1 Hz from the signal generator...it

For Deltaapplication you need to reinstall TinyOS using moteiv's distribution, Boomerang, from www.moteiv.com, the latest version is 2.0.4
There is acommunicative difference between SurgeTelos and Delta, the routing algorithm.
SurgeTelos uses tree-based routing, Delta uses Sensornet Protocol(SP).
Dear Dr.Levis,
Finally i solved, there was an error in a script. Thanks very much for your
help.
Instead i don't understand why, when i switch back to 1.x, i cannot compile
apps no more, while in 2.x yes. I'm following the instructions for changing the
paths but nothing...in the attached file
I don't know if this is what you mean, but if you have this in your code:dbg(DBG_USR3,"Message to show on terminal");in order to see the message you should execute your program this way:DBG=usr3 build/pc/main.exe -l=1.0 1(-l=1.0 1 are options that you can change)primalfear 69 [EMAIL PROTECTED]
Have you compiled the Listen application?Look into the Listen application directory and see if you have only .java files or .java and .class files. If you only have .java files you need to compile the java tools. There must be some Makefile under tinyos-1.x/tools/java/net to compile all the java
As far as I know, tasks do not preempt other tasks, but events can always preempt tasks or events no matter whether they are async or not. Tasks are executed only when there is nothing else to do, and can be preempted by events, but not by other tasks.If someone knows exactly the difference
Hi.I want to compile a program for PC (in order to debug it). The program compiles for tmote without any problem, but it won't compile for PC beacuse of the interface LocalTime (looks like it is not implemented for the PC platform). Is there any way of circumventing this problem?Thanks in advance

If, for example, the execution context is async and a non-async event is
to be signaled, the code posts a task which then signals the event.
I didn't get it. A task can't be async, 'the execution context' is an event?

The backoffs are implemented in CC2420CsmaP.nc.
You can use the CCA (clear channel assessment) to check for energy on
the air. See the datasheet for more details.

I want to understand the Application SurgeTelos. I have some doubts if anyone can help me in clearing them:

I see this declaration:
static const prog_uchar
CC1K_LPL_PreambleLength[CC1K_LPL_STATES*2]
it say that is a constant defined on flash (only
read). I want to do the same thing for save memory, so
static const is enough, and the use the PRG_RDB
macro. Yes? where is defined this macro?
Hi,
Reading the interface file for SysTime.nc, it says on the mica2
platform the current implementation uses a 1/8 prescaler that results in a
921.6 KHzclock frequency. When using the interface I get a large 32-bit value.
Can someone tell me what this value means, i.e. does it start from
Yes.
Following the examples given in the CC1000 radio stack - TinyOS 1.x uses
static const prog_uchar ... to define the array stored into program
memory, and then PRG_RDB(..) reads in a byte from program memory.
TinyOS 2.x uses static const_uint8_t ... to define the array stored in
program
I would like to know if you thik if the progran listenraw could be modificated in java for sending for another serial port the sensing information sensed by motes an collected by MIB510. The application is to convert the packets in a pc with a modified program of listen raw and send for a rs232

Your compiler is trying to help you by padding the single byte
to put the next field on an even boundary. I think there are
some options to nescc syntax that shut off the padding.
Look for padding or packing in the doc. This has also

All things are (im)possible with software...
But probably all you need to do is redirect ListenRaw output

or whatever the port name is...
Do man bash and look for I/O redirection information.

They are different things. An event is like a callback function while
a task is a context in which code can execute. If, for example, the

Actually I read CC2420CsmaP.nc before I wrote the first email, its Send.send() just modifies some states and eventually calls CC2420Transmit.sendCCA( m_msg ), which is the function that I mentioned in my first email.
I have tracked CC2420Transmit.sendCCA(). It basically calls an internal

In summary, you stopped too early when tracing the code. After loading

backs off for that period of time.
