Hello.

I'm new on X10 and home automation, but have been on electronics for
several years.

I'm looking for some OEM module or "all-in-one" chip containing all
the circuitry for signal_processing->mo/dem->decoder for building my
own X-10 appliances. I can use several microcontrollers I have
experience on, and I just need some kind of asic IC or so to make all
the stuff regarding the X-10 protocol and interface with power line.

Any help would be appreciated, because I have not found anything yet
for this.

PicBasic Pro has macro functions to send/receive X10 commands with a
PIC. The X10 chip does the decoding but
you're gonna need an oscillator and line isolation components.
Unless you need a LOT of 'em, it's hard to imagine building one cheaper
than you can buy a module. If you're using a computer for the transmit
end, a firecracker module is the easiest way to go.
There's a ton of info on the web. Google is your friend.

Well, let's take another view.

I started talking about X-10 because it seems popular, and it made me
think I would find lots of info about it. But let's assume I have no
preference.

I only need to send/receive commands over the power line (in my case
es 220V 50Hz, Spain), and I need it with the simplest solution, in
terms of price and circuit simplicity.

I would like to know there is some IC which I can feed with the power
line signal (after some treatment), connect 8 dip switches to 8 pins
to fill the code, and receive a digital signal 0/1 on some other pin
(for a receiver, reverse for a transceiver).

Any other protocol available for this?

By the way, what is a firecracker???

Regards.,
Eduardo Gimeno

Hello Eduardo,

es 220V 50Hz, Spain), and I need it with the simplest solution, in
terms of price and circuit simplicity.

It depends on how reliable it has to be. Personally I would not control
anything critical with X10. Other than that it works for us.
Any other protocol available for this?

Several, such as Lonworks. But then it gets expensive.
By the way, what is a firecracker???

A device that plugs into your PC. It sends X10 RF commands to the
wireless transceiver instead of using a powerline modem like we do.

Whatever you do, make sure it is geared towards 50Hz. The X10 modules we
are using in the US are set for 60Hz. For a reasonable signal to noise
ratio you need to have the 120kHz bursts of X10 happen at the zero
crossing. Or at least near those.

Saludos, Joerg

If you're building a zillion, that may be the right question to ask.
If you're building one, you're probably better off buying a solution.
Messing with the power line when you don't know what you're doing is
an invitation for a fire truck.
I would like to know there is some IC which I can feed with the power
line signal (after some treatment),

And that "treatment" is the problem. Safety issues, reliability issues
for hardware and data.

You can buy devices that can connect your modem over the power line.
My experience was that the performance was horrible...when they worked
at all.

connect 8 dip switches to 8 pins
to fill the code, and receive a digital signal 0/1 on some other pin
(for a receiver, reverse for a transceiver).

google firecracker x10, you can't miss it.

Let's retake the subject, because it resulted in a discussion about
pahses and so on...

The micromint PLIX chip seemed perfect for the task until I found out
I also needed another module (TW523) whose size is huge (apart from
the cost).

Once again, I don't want to shut the doors just to X-10. I need an
easy to implement and unexpensive protocol to communicate over the
PLC. Even I can lay a data cable for this matter, because I have a
spare electrical tube between each pair of boxes I asked just for this
purpose. When I heard about X-10 I thought I wouldn't need to use the
spare tube, but now when I see the complexity, I do not discard using
it.

Someone mentioned Lonworks. Does it make my problem easy to solve?

Another commands protocol for remote switching over the PLC, or over a
dedicated data line which can be implemented mostly on one chip and
unexpensively?

Thanks!
Eduardo.
