Hi Eric,
The SAM4 is very similar to the SAM3. Shouldn't be too difficult to get it
up and running on it. You will have to enable the compiler flags for
hardware floats if that's why you want to use a SAM4 though.

This is how the radio chip works, and not the TinyOS implementation. This
is how the radio decides if it received a 0 or a 1. TinyOS can only access
the final result, not the actual value used for the soft decision.

Hi,
Fairly simple, the FTSP paper was based on the Mica2 (or was it the MicaZ?)
which has a higher frequency crystal. You can do a similar thing with the
TelosB, but you will have to change some of the code. Search the mailing
list. There were long threads discussing how to do that.

Not sure how you are synchronizing, but have a look at how packet
timestamps are implemented. You get a timestamp at transmit (SFD rise
on the transmitter) that gets added to the packet that is about to be

The only thing I can think of why not to switch to higher DCO is power
draw. The same counts for setting SMCLK to DCO instead of DCO/4. Even
though all the peripherals can divide it down, power draw is likely to

That depends greatly on your chip. The msp430 on the telosb and epic does

What specifically is segfaulting? If it is during compilation, then

Hi Sinan,
The problem is not in the TinyOS code. The hardware you use (I assume
TelosB or Sky?) does not support these timestamps by default. The
timestamps are taken when the SFD line toggles. This line is connected
to the TimerB, which is sourced from the 32kHz signal. Thus, you can
not get micr
The msp430 can go down that far, the cc2420 radio not. While you might
be lucky and the TelosB might work at that voltage, it is definitely
out of spec. Minimum voltage for the CC2420 is 2.1V. This should have
been the same for older Telos motes, as they used the same radio.

You don't have the tinyos tools installed in root, i.e., don't use sudo!
your /opt/tinyos-2.1.1 directory probably has the wrong permissions.
Two sollutions:
1. use a TinyOS VM with all the tools correctly installed
2. sudo chmod asus:asus /opt/tinyos-2.1.1 -R
cd /opt/tinyos-2.1.1/apps/Blink
How did you measure the 8ms? Remember, you also have to "upload" the
message into the radio over
SPI, and "download" it from the radio. That takes time too. Oh, and
what platform and target are you using?

Hi Kartik,
Generally, that's not possible as the radio is a packed based radio.
However, depending on what you want to do, you can frame the bytes you want

If you really need microsecond accuracy, then you will have to add an
