Can you clarify the word 'soon'? The Microchip 802.15.4 & ZigBee
development seems to have been dormant for while, are they actually
producing silicon now?

What functionality does the Zigbee stack encompass?

Microchip indeed has a Zigbee stack. The only prerequisite is that you
use a PIC18 with greater than or equal to 16K of flash. Watch for it
to come out soon. They will be selling something called the "Picdem
Z". Look out for that too.

In fact, here is the link:

I've seen some programs on the chipcon website but they're specific to I 
think ATMEL chips.  If anybody has a Microchip stack I'd be interested 
in this too.

Indeed I hadn't :-)

Night? It's 8:45 in the morning over here in Europe (you know where that is,
don't you?).
The world is slightly bigger than the confined space called USA.....

hello beautiful comp.arch.embedded world!  how are you feeling this fine 
night?


i've been developing a DIY home automation network for five or six years 
now, and its evolved in a number of ways.  one of the final goals was 
always going to be to attach some form of RF system and make the whole 
shebang wireless.  well, i'm proud to say, its finally at that point!

it seems like there's actually a plethora of zigbee hardware out there, 
which i like.  what i'm not sure about is how what is required to do 
devel work, most prominently on the software side.  what do zigbee 
stacks actually do?  are they all vendor specific, or does the MAC/PHY 
specify a strict enough interface guidelines to make this generic?  i'm 
still on a student hobbyist budget, where should i look for low cost 
solutions?

my other question is, what is required for mesh operation of Zigbee, and 
how do you configure your mesh system?  it is my understanding that 
zigbee was crafted ground up to be a "mesh" system.  this would seem to 
imply that there is a coperative standard in place.  none-the-less, it 
seems intuitive that there would still be some level of control over the 
network to let you create dispirate networks, or to prevent a battery 
powered remote from acting as a central relay.


many thanks!
