Reading tep 126 cc2420 radio stack I don't understand this :
The current CC2420 stack uses software acknowledgements, which have a higher
drop percentage. When used with the UniqueSend and UniqueReceive interfaces,
dropped acknowledgements are more desirable than false acknowledgements.
What interface should I use?
I am using telosb platform.
Thanks,
Jin

Hi,
I installed the tinyos system on windos xp by cygwin (AVR + 2420). I
install all the software successfully, but when I test the 'blink' program
using 'make micaz sim', it shows ' No such file or directory.

Hello,
Can we change the node ID ( TOSH_NODE_ID ) dynamically during runtime?
As far as I understand, we specify the node id while programming the mote.
eg: make micaz install.5
Apart from this, is there a way to set the node ID programmatically?
Thanks

You aren't.

Hi,
I am currently using TinyOS2.x, and tyring to use microseconds in mica platform.
I used CounterMicro32C to get microsec counter, and after awhile, the return
value becomes negative value.
CounterMicro32C provides interface Counter with uint32_t format, but why am I
getting negative values
Yup, you're not going to be doing many floating point matrix
calculations on a Mote...hope you can squeeze your algorithm
down to where it works.

Are you maybe converting the uint32_t into an int32_t? How do you know
it is negative? Because a uint32_t is never negative, per definition,
except if you cast it into a different signed type.

Who says it's negative?
When a signed integer's top bit gets set it becomes negative.
Somewhere along the way your unsigned variable is being mis-interpreted.
Often the default behavior is signed, so make sure you are using the
right declarations and casts.
Java doesn't know from unsigned, so
it seems that I (maybe partially..) solved it.
That's what I've done:
installed gcc 4.3.4 from macports
changed gcc soft link (in /usr/bin) to point the new version
and:
*** Successfully built micaz TOSSIM library
did some basic tests in python and (as for now) it seems to be working.
Thank you.
I didn't cast the return value, so I'm geussing I misused printf.
I did printf(%ld, call Counter.get());. I checked TestPrintfC.nc of
tutorial/Printf, and it uses %ld for uint32_t, so I assumed %ld is for uin32_t
format. Can anyone tell if I am using printf correctly?

I think you have interpreted things correctly, although if you
are using a telos mote I thought it maintained the CC2420 radio
header throughout -- but that looks like the old familiar
types/AM.h header. The last two bytes should be the CRC.
You will have to go look at the program you are using
I am not aware of many people that are still using tinyos 1.x, so I

CFLAGS is usually the flags you pass to gcc (or in this case ncc). It

I really can't help with that because I don't know what you are
trying to design. If your sensor works just like the photo cell
on one of the boards you might just be able to solder it in place.
Otherwise the mda100 may have room to attach whatever you need.
I haven't used any of them though.
