[Tinyos-help] RandomLFSR:please help!

2006-05-29 Thread Munaretto, Daniel
Hi all,
i have a problem after using RandomLFSR. I used it on my program, now i turn 
back but when i compile it results that in /tos/lib/CC2420RadioC.nc component 
RandomLFSR not found and no match...it gives me an error of this 
kind...incredible..also the simulator shows many strange debug messages and not 
the radio packets as before (with standard fields like data, adresses, etc.).
Please help me!
Daniele

[Tinyos-help] help with simulator(but RandomLFSR solved!)

2006-05-29 Thread Munaretto, Daniel
Hi,
  i solved the problem with RandomLFSR but now the simulator doesn't show only 
my debug messages (i created in my program) and sent packet radio, but also new 
messages like booting and other ones that are not interesting. And now the 
simulation is really slow.
Why this changing of behaviour?i'd like to turn back to my original screen 
where only sent messages and my debug messages are shown..
Daniele

[Tinyos-help] Connecting an External Antenna to TMote

2006-05-29 Thread Preethi Naveen
Hi,

I am interested in connecting an external antenna to extend the range of tmote. I have been through the tmote data sheet which explains shifting of the capacitor for external connection. I would like to know if issues such as impedance matching of antenna is taken care of if i use the SMA connector supplied by digilink. Any other precautions/tips towards connecting an external antenna would be very helpful.


Thanks
Naveen

Hi all,
  
 I want to know which MAC protocol is used and where can i find the
actual code of it. Genericcomm, MACcontrol etc just handle tasks like
send.sendmsg and receive.receivemsg. But i want to see how it is being
sent and received.
  
Thanks,

Hello,

What means 'asyncronous' command or event? What's the
difference between an asyncronous and a not
asyncronous command or event?

Thanks.

You need to connect an antenna that has an impedance of 50 ohms at 2.4GHz.

I already tried to recompile the nesc compiler with the patch that was 
suggested in :

https://mail.millennium.berkeley.edu/pipermail/tinyos-help/2005-September/012219.html
but it doesnt work.

I tried to change the offestof() macro in stddef.h to the old function, 
but i dont know how to do that.

Can anyone help me with this?


  lg, mike
