Ian a few  of us have been trying  to formulate an rs 485 protocol to
use..=
.Ian Bird + Paul Barrett (xAP) and Neil Wrighton and myself (xPL), Paul
has=
done an initial draught although theres still quite a bit of work to be do=
ne....The idea is any hardware developed by either xAP or xPL can be used 
=
by both groups......

I thought Tony had done this ???

How about you Frank - what's on your project plate just now?

Just the implementation of reading dallas temp sensors with my probe
system=
....and when Gerry,s boards arrive i hope to install a few of them...

Yes and no...

I finished it, and it worked.. kinda. The problem was the power supply
available from the KR400 curtain motor was a little unstable, and the
PIC kept resetting. I also found a stack of problems with my PCB layout,
and the fixes were getting silly!

I'm using X10 control for now, and doing a wee redesign on the
boards/code.

The other thing that stalled me was fumbling around for a bus system - I
had been using RS485, but that worked only randomly as I wasn't doing
any sort of token passing etc. It also meant that, fundamentally, I was
coming back to a PC port.

I started down the Ethernet path, but that's fraught with issues of it's
own - most notably that "C" is pretty much the only show in town
when it
comes to Ethernet stacks for PIC and I don't (didn't) speak C.

On the go at the moment... nothing well enough formed that you could
call it a project, just a stack of tools that are starting to do stuff.

I have a good programmer now, and using the wee modtronix
serial/Ethernet board I'm getting somewhere at last.

I guess I have to figure out an RS485 bus system with some kind of
packet encapsulation, token passing thing going on, as that will let me
do most of the stuff I want to do..=20

The other missing part then becomes an xPL Serial/Ethernet gateway with
filtering capability, so that the devices "out there" on the
RS485 bus
can talk straight to and from the Ethernet side.

I'm thinking that having an embedded version of xPLHal that could run on
a wee dedicated box would be kinda cool, but that's very embryonic - I
got as far as trying to build a Windows CE image for a MiniITX board
booting from Compact Flash, and that's quite promising, especially as
the .NET compact framework seems pretty powerful.

Oh that and I dug out my original UIRT to have a play again - there's
mileage there to be sure, and the fact that yourself and Keith now have
working IR distro down perfectly with Firm/KAT5... I figure that an
Ethernet connected IR injector/receiver would be kinda cool also.

The limiting factors are, of course, time and money (I run a wee company
that's been going though some tough times, and that eats a lot of hobby
time, as well as curtailing the toy budget somewhat!). I have been a lot
more active lately as things improve, so I'm hopeful that the coming
year will give me more time to do all this cool stuff!
How about you Frank - what's on your project=20
plate just now?

Hi Ian

>Only how obsessed I am about native xPL devices ;)

Did you ever finish your xPL curtain controller ????

Any hardware projects on the go ????

Frank

Only how obsessed I am about native xPL devices ;)

Couple of things - if you are using xpldevcom, then your device *is*
native xPL, if using a gateway app like the Probe app, it's not..

There's no real benefit in going native xPL for the device at present.

Ian.

Ps> note the tantalising "at present" ;)
