i'm in trouble...help me please...

[texas5]

i want to transmit data using x-10 powerline communication and receive the data at the receiver.but i don't have an idea how to do it.basically i just want to turn the LED at the receiver by just push the button at the transmitter.that all.please someone help me...

Look at the XOUT command in the manual and look at the info Dave Houston has on his site http://www.davehouston.net/
Should get you started.

yes, i've look a the xin & xout command but i can't understand.how can i timing the 120khz to burst at each zero crossing???help me please.

Hi, Texas

It would be Very Kind from you to give the subject of your "troubles" in the Thread title ...

Thank you

Unless I'm mistaken, doesn't using the XIN/XOUT commands remove the end user from having to worry about any of the hardware functions, other than the actual X10 modules themselves?

XOUT takes care of this for you.
From the manual:

XOUT only processes data at each zero crossing of the AC power line as received on ZeroPin. If there are no transitions on this line, XOUT will effectively wait forever.

Do you have an X10 module?

i refer to application note from microchip(an236) with a little modification(use only push button not push button + LCD).does xout & xin in the picbasic are x-10 driver.if so,that means i only have to command the xout & xin because i only want to "turn the LED at the receiver by just push the button at the transmitter".can i do that???

XIN/XOUT receives or sends commands from/to the X10 module.

From the manual:

XOUT is used to send control information to X-10 modules. These modules are available from a wide variety of sources under several trade names. An interface is required to connect the microcontroller to the AC power line. Either the PL-513 for send only, or the TW-523 for two-way X-10 communications are required. These devices contain the power line interface and isolate the microcontroller from the AC line. Since the X-10 format is patented, these interfaces also cover the license fees.

i've design the x-10 module using the application note from microchip(an236).

Hi,

As mackrackit pointed out, XIN and XOUT are to be used with X10's interface modules PL513 (transmit only) or TW523 (transmit and receive). If you intend to build your own mains-to-pic interface, you cannot use XIN; you will have to write your own code to receive the X10 signal.

XOUT you could still use, as long as you get the mains interfacing right.

Remember you are playing with mains voltages here.

ok.thanx a lot guys...

[texas5]

and one more thing.can someone guide me where do i need to start the coding.my main idea is...

transmitter:
1.press push button
2.detect each zero crossing(i don't know how to play with the delay)
3.burst 120khz(i don't know how to play with the delay)

receiver:
1.detect each zero crossing(i don't know how to play with the delay)
2.get started data (in this case, bit 1)
3.get another data (in this case, bit 1 or 0)
4.stored data
5.called back the data(if 1 1=on led...if 1 0=off led)

i really hope someone can guide me....please....

Are you going to use off the shelf modules or try to make you own?

I will advise against making your own modules.
