You can set the default output power in the Makefile of your
application, with a line like this:

PFLAGS += -DCC2420_DEF_RFPOWER=7

If you do not define CC2420_DEF_RFPOWER, the default is 3, I think: the
lowest TX power setting defined in the datasheet. Look in the CC2420
driver for details (just search for CC2420_DEF_RFPOWER in the TinyOS
source tree to find the right spot).

RE: AVR GCC compiler problems

Function arguments, from left to right, are passed in registers r25 to r8. All arguments take up even number
of registers, so if you have a 8-bit argument, then the upper register of the register pair is not used.
Stack is only used if the arguments can't be fit into the available registers, or for variable-lenght
argument lists.

In this specific case, channel is allocated in r24, id in r23:r22:r21:r20 and mask in r19:r18:r17:r16. As
you can see, r24 and r23:r22:r21:r20 are properly set for the second call, but r19:r18:r17:r16 are not.
For some reason, avr-gcc assumes that r19:r18:r17:r16 are not changed by the function that is called.

Can you check where in the called function r19:r18:r17:r16 are changed?

Janos

Below this words, there is the last mail that I sent to tinyos-help. Check the last two "push" at address
00000A4A and 00000A4B. The pushed registers, shouldn't be R18 and R19 instead of R28 and R29? I'm using
AT90CAN128, and TinyOS 1.1

Re: lost packets and nss file

Maybe your line ending in .nss topology file is carriage return (0x0D) + line feed (0x0A) (Windows)

In .nss file, line ending must be a line feed (0x0A) only (Unix)

Hope that helps

Hi every body,

When I ran surge application, the DBG route didn't show me lost packet as it is viewed bellow:
3: MultiHopLEPSM: Updating Nbr 4. ExpTotl = 5, rcvd= 43, missed = 0

Always (zero).

In addition, although I defined .nss file like this:
0:1:0.555
0:4:1
1:2:0.666
1:3:1
2:3:1
2:0:1
3:4:0.750
4:0:0.250
4:1:1

my topology showed me only connections between Node N° 0 and others (neither links between 1 and 3 nor 1 and 2 etc...)
I will be very grateful if you answer very soon
Thanks a lot.

Re: Output Power levels CC2420




You can set the default output power in the Makefile of your
application, with a line like this:

PFLAGS += -DCC2420_DEF_RFPOWER=7

If you do not define CC2420_DEF_RFPOWER, the default is 3, I think: the
lowest TX power setting defined in the datasheet. Look in the CC2420
driver for details (just search for CC2420_DEF_RFPOWER in the TinyOS
source tree to find the right spot).


Just as a side note, the default value for CC2024_DEF_RFPOWER is 31 if nothing else is specified
From  tos/chips/cc2420/CC2420.h :

#ifndef CC2420_DEF_RFPOWER
#define CC2420_DEF_RFPOWER 31
#endif

Cheers

message received in TOSBase from OscilloscopeRF

Hi,

I have a question regarding the radio message received by the TOSbase application from the oscilloscopeRF application.

in the TOSBaseM module UARTSendTask, the uartQueueBufs represents the message received from the radio. does the UARTSendTask sends this message to the UART with its originally computed CRC (CRC computed before being transmitted over the radio) ? or it omits this radio CRC and sends the 31 byte length message coming from the oscilloscopeRF application without its original CRC and computes another one based on the UART data format?

in other words, i need to edit the data received from the radio by the TOSBase module before sending it to the UART (for example divide it into two packets and call the sending task twice), does anybody know where exactly can i edit this data before calling the UARTSend.send task? in case i edited this data, shall i recompute the CRC for it again before giving it to the UARTSend.send task or the UARTSend.send task will do the job?

in case i need to re-compute the CRC shall this be done for the whole TOS_MSG (header and payload)

i hope i made myself clear.

many thanks in advance,
Nashwa

Photo sensor on telosb ( tinyos-2.x )

Dear All:
I am working on Tinyos-2.x using telosb and need the data from the
onboard sensor HamamatsuS1087. Since the DemoSensorC in 2.x is not wired
to HamamatsuS1087, I have to modify it as follows in Oscilloscope.
{
     //new DemoSensorC() as Sensor,
    , new HamamatsuS10871TsrC() as Sensor
    ...
    OscilloscopeC.Read -> Sensor;
}
Then I got the returned values by java net.tinyos.tools.Listen like
 03 E8
 04 45
 04 59
 04 45
 04 47
 04 39
 00 02
 00 02
 00 02
 00 03
 00 02
 00 01
 00 04
Converting to decimal the brightest is 1113 (04 59) and the darkest is 1
(00 01). Does anyone know if these data are valid?
And what is the unit of these value. is it Lux? Thanks.

Steven

Re: what is significance of fuses ??

They make various configuration selections on the controller chip,
such as clock speed and source. For the Atmega you can find a table
of values at around page 290 of the chip manual (in the version that
I have anyway).

Re: about power detect

Search back on this list for a lot of discussion on battery life.
But the basic answer is: you can't.
