Hi Lehane,
Thanks for the feedback.
I might consider adding Ethernet and use POE as another board option if I
can't fit it on this one board. I'll have a play in the next day or so and
see what I can fit on the board.
Yes, the idea was to use the Mesh network so that I don't have to include
some form of master slave communications protocol. I still have a bit to
learn and get this working but I already have a USB to Zigbee module and a
couple of other modules to do development with. I need a second JTAG ICE
though to be able to do 2 units at the same time.
Have you looked at using the likes of Front Panel Express from Germany
(http://www.schaeffer-ag.de/) for
making some very nice panels. They have
Perspex available in clear or red but not sure RED would be WAF!! The other
material is anodised aluminium and you can make some pretty professional
looking panels for a reasonable cost, especially for small batches. I even
use them for commercial projects. The natural panel is a very nice finish
and they can install small threaded inserts or bushings on the read for
mounting the LCD's etc so avoiding any screws on the front face.
I had planned on simple plastic faceplates or I could use the Zigbee
modules
with the external whip antenna but that adds cost and the issue of where to
put the antenna on the unit.
Regards
Dave...

Hi Dave,
Looks very interesting.
I've been playing around with the larger 2.8" units from SK Pang in
the UK
and a breadboard PIC24F with Ethernet from a Wiznet board but its stalled a
bit over the summer and isn't at the PCB stage (and may never be!).
My personal favourite is POE rather than Zigbee as it makes hooking the
device to Ethernet/xAP easier. Been down the RS485 route but wouldn't
again.....
Presumably the thought is to have an xAP to Zigbee mesh bridge under
Windows
and use the MeshNetics stack on the Atmel longer term? This would hide the
internal menuing application (I guess) and present one (or more) devices to
xAP.
One issue I did find with these small screens is how to get decent bezels
that aren't cheap plastic (in my case Stainless is needed) have WAF and fit
UK back boxes - http://www.mm-wave.com/honeycottage/xaplcd2.htm
Oh, that's
the other issue with RF - metal back box and metal bezel = (nearly) no RF
:-( Clearly in some situations there will be plastic cavity back boxes
which
will be better.
Regards,
Lehane
