Hi all,
I'm working on a sampling program on mica2dot. Now, I'm using a timer to
start one sampling procedure repeatedly. But it's not efficient for high
frequency sampling. On micaz, a command can be called to start a continuous
sampling without triggering of a timer (call Sample.getSample()).
Hello everyone,
I have a problem on mica2dot's CC1000. It often got locked somewhere before
SendDone was called. Sometimes it returned back to normal after a while,
sometimes it never. I tried to restart radio using RadioControl.stop() and
RadioControl.start() before every transmission, which
Hello Danielle,
My TinyOS version is 1.17. There are two errors in the SetRFPower command in
CC2420ControlM.nc. I corrected and it works now.
I don't know what version you are using. Maybe it has already been corrected
in new release. You may look through the code and the CC2420 datasheet. The
at the basestation. It
may well be a problem in my code, but I didn't find anything suspect.
I'm sorry it doesn't help you, I just wanted to report the problem
since it may be related. I would appreciate as well any clue or
explanation.
Cheers,
Romain

Hello, all,
I'm working on a simple program on mica2dot to achieve a function of
sampling with a given rate, saying 2 Hz, and then transmitting the result
immediately. I used a timer to trigger the sampling, as what is done in
XSensorMDA500.
With the help of the LED, I found the timer was not
was, LNAMIX_GAINMODE was
always 3 (high gain), and the VGA_GAIN was almost always between 0x7B to
0x7E. We did not see any meaningful information on it.
Does anyone know something about AGC of CC2420? Please help. Thank you.
Best Regards,

:
Are you going to get the time when the msg being sent, or the time that you received it?
For the former, you can use metadata defined in T2 (I think T1 has a corresponding part), for the latter, simple use a timer.getNow().Tie

Hi, Sean,I had some problems when I was trying to write and read to/from flash on MICAz. But now it works very well. You need the component, Logger; and the interfaces are Logger.LoggerWrite and Logger.LoggerRead.
Look through the files in apps\SensorLightToLog, you will find them. If it still
don't have Step 3., channel can switch very well. But if the mote sends messages using the new channel (11), it seems it can't switch back to 26, even though I put a delay timer after the sending.
Anybody has some ideas? Thanks!regards,Lei Tang

Hi, I'm trying to write and read data to/from the flash memory too. My platform is Micaz and mib510. I found an example in tinyos-1.x/apps/senselighttolog, which seems being designed not for micaz. I used interface LoggerWrite and LoggerRead, but have some problems. Hope somebody can help me.
Hi, AndresCC2420Control.SetRFPower(uint8_t power) is in CC2420ControlM.nc.Add interface CC2420Control to YourProjectM.nc and component CC2420RadioC to YourProject.nc, and hopefully you can call setRFPower() and other functions to change the radio's configuration.

didn't see the
data section (0xf) in Msg. Did I make a right packet? How could I send data to base mote throught UART correctly? Thanks! Best, Lei Tang

Hi, all,I'm working on MICAz and MIB510 to find out the maximum payload (user's data) of a package. I found the parameter, TOSH_DATA_LENGTH, in the file of 'AM.h' and the default is 29. I changed it into some larger values, and then made a package in my code complying to the size. But, it doen't
