hello Michael Schippling,
please i mistakenly deleted the mail you sent to me cos it went to my bulk mail. i had already clicked on the delete button before seeing the mail. on going back i couldn't open it again.
'''
hello all,
i am very new to tinyos and i need to get some fundamental knowledge. Sorry my question may seem like that of a novice, but i need help. i just installed tiny OS, but i would like to know how i can port it to an Atmega128 microprocessor. what i'm i expected to get as output if succesful. What features do i see in the output, can i make any changes to observe any kind of differences in my alterations.
thanks, help the soul that searches for knowledge. ''''

I am trying to print RSSI strength in the recieved broadcast packet. First
i was trying to access in tinyos-1.0 but i came to know that it is not
possible in this version. I upload my tinyos to 1.15 but i am getting the
value as zero only. Has ne one else came thru similar problem?

of course, i'm assuming you're using a windows based PC and are using a
generic serial port access software (MATLAB, java etc.) to write to the
serial port.

i was able to get it. what seems to be the problem?
all i did was access the message->strength value.

It runs on both the mica (mica, mica2, micaZ) and telos (Telos revA,
Telos revB, and TMote) families. When compiling for the Telos revA
you have to follow a slightly different build process due to its RAM
limitations, revB and TMote are no problem. There is support for the
basic mica sensor board (light/temp), the mica sensor board (the one
with the sounder, accelerometers, magnetometer, etc.), and the Telos
sensors.

By the use of "print" I think you may be trying to get the strength
on the host PC? If so, it ain't there. It's only available in the
TOS_Msg structs on the mote end of the world, and is not passed
over the UART to the host.

dear sanskar,
1) which version of tinyos did u use?
2) i am attaching my code for recieved packet.
event TOS_MsgPtr ReceiveIntMsg.receive(TOS_MsgPtr m) {
TOS_MsgPtr ret = m;
IntMsgnew*message = (IntMsgnew *)m->data;
atomic{receivednode=message->src;}
// call ADC.getData();
// call ADCBattery.getData();
updateNeighbors(message->src,message->val,message->seqNo);
dbg(DBG_USR1,"strength %d",m->strength); --> this is how i am trying
to access...
// printNeighbors();
call Leds.redToggle();
ret = m;
this is a simple code i have written for recieved packet..i dont know wat
seems to be the problem. can u make out some mistake?

well,
this is my (a colleague's) code:
Receive.receive(TOS_MsgPtr m)
IntMsg *message=(IntMsg*)buffer.data;
message->val=m->strength;
....
doesn't look too different.
although our experiments were done on the actual motes and we broadcast
the value in a message packet as you can see.
