Hi,
Did any one implemented TPSN in T2. If any one could forward working code of
TPSN in T2 that would be great. I couldn't find the code in CVS forum.
Thanks

Hello all :
thank you very much for your reply .
i have seen deluge-t2-manual.html , there is a word "In addition, it
provides a quick test for software prerequisite. The latest TinyOS 2 CVS
tree and Python 2.4 with pySerial support are recommended for running Deluge
T2.". so i have update my tinyos tree to cvs version , but the tools
installed are the same with tinyos2.02 except python, i update it to 2.4
. but when i typed 'python' in cygwin , i display that i still use the
version 2.3.4 not 2.4 . what is wrong ? is there something i should set ?
can you give me some cues about the tools if i want to use deluge rightly ?
it's better give me a link to the tools so i can download it and the way how
to set something .
thank you !!

Hello all :
thank you very much for your reply .
1.mica2 and micaz use the same microprocessor and both of them use the
same external flash at45db . i think the hardware platforms are the same to
deluge . why only micaz is supported in tinyos 2.x ?
2. i use tinyos2.x cvs tree . is it the same as tinyos-2.x.git ?
thank you !!

So, this last line is what's causing the error. Did you update -d? Do
you have lib/safe? Does this file exist?

The SPI pins (SCLK, MISO, MOSI) and a digital I/O pin for chip select.
So, the same pins as the CC2420, except you need a separate chip select.

Uh -- I'll see if I can find it somewhere.

Why not use an SPI client? That way, software (through an arbiter) can
make sure two peripherals don't try to use the bus at the same time.
The CC2420 stack will only use the SPI when it needs it.

Yes.

No, the CC2420 releases the SPI when it does not need it. On Telos,
for example, the SPI is also used for the flash chip.

CTP should definitely avoid a situation like this. In that, the
implementation should, and it's a bug that it doesn't.
In theory, what CTP should do is detect that the link to the root is
dead (has very high ETX cost) and stop using it. E.g., 5 will detect
that the link to 0 is bad, realize it doesn't have a route, send a
beacon with the pull bit, and then hear 3 advertise its route, which
won't be through 5 since 5 advertises no route.
What would be *really* useful is a log from node 5.... but we'll see
if we can piece things together from 0, 1, and 2.

No, that's in TinyOS 1.x. In TinyOS 2.x, TOSSIM is platform-specific.
