Uno with e-net shield.  Works fine with html page turning on and off the one LED you see in the code.  I altered the code to include the X10 code examples.  Color of wires from RJ11 plug are commented in the code to help any troubleshooting.  Using an X10 CM11A 2-way controller.

Issue:  I can't get to the point of troubleshooting the actual x10 stuff because something isn't playing nice in the html code at the bottom where I call the X10 commands.  With X10 commands at the bottom lines of code, I can turn on and off my one original LED on the html page UNTIL I try to turn on the other button now linked to the X10 command.  If I comment out the if(.... statements with the X10 code after it at the bottom, html plays nice and original LED works.  So something isn't working down there.

After trying the button linked to X10 commands, webpage also will crash.  

Help is appreciated, I edit "working" code from others and include it to do what I want, I don't have a lot of html or C++ experience.

I find thing seem to work better to send back the web page first and close the connection before actually controlling things on the arduino. Have you gotten the x10 stuff working just using commands from the serial monitor?

Alright, back to basics..........I went here:  http://www.arduino.cc/en/Tutorial/X10

I downloaded and placed the libraries in that tutorial in the appropriate places and all compiles fine.  I have the same issue others had with the sketch getting to print in the serial monitor:  lights on and never does anything else.

I have a CM11A.  Pin 1 is yellow, Pin 2 is green, Pin 3 is red, Pin 4 is black.  I have it hooked up as in the tutorial. It's not getting past that in the program.  The library I used from the tutorial doesn't have a .O file to delete like some of the other forum topic on this issue.  I thought Hogan stated that that tutorial DOES work with that library if wired correctly.

Not sure what I'm doing wrong.  I also tried a few other libraries and examples and none worked.

I tried Hogan's library link on the transmit AND receive he did, but #include <x10constants.h> has a compile error.  At this point I would like somebody to essentially point me to EXACTLY the library, example program, and wires for a CM11A.

I have this one hooked up as others say they have, and no dice.

 I am using the blink example sketch in the folder with those library files:

Code:
/*
  X10 blink
 
 Blinks an lamp on an X10 lamp module.  
 Example was built using a PL513
 X10 One-Way Interface Module from http://www.smarthome.com
 as the modem, and a Powerhouse X10 Lamp Module from Smarthome
 to plug the lamp in.

#include <x10.h>

const int rxPin = 3;    // data receive pin
const int txPin = 4;    // data transmit pin
const int zcPin = 2;    // zero crossing pin


void setup() {
  // initialize serial and X10:
  Serial.begin(9600);
  x10.begin(rxPin, txPin, zcPin);
}

void loop() {
  // open transmission to house code A:
  x10.beginTransmission(A);
  Serial.println("Lights on:");
  // send a "lights on" command:
  x10.write(ON);

Just as a followup on some x10 stuff, I tried the below code with my x10 CM17A "firecracker" and it works with the TM751 transceiver. Just ground and arduino pins 2 and 3 connected to the cm17a.

Code:

 * A MAX232 is not req. (0/+5V work OK) If MAX232 IS used reverse all HIGHs & LOWS
 * Signal      RTS DTR        Standby | '1' | Wait | '0' | Wait | '1' | Wait...
 * Reset        0   0         _____________________       _____________________
 * Logical '1'  1   0   RTS _|                     |_____|

 * Standby      1   1   DTR _|        |_____|                   |_____|

 * MINIMUM time for the '1', '0' and 'Wait' states is 0.5ms.

That probably will work, once the right hardware arrives in the mail.   smiley-evil

I have a CM11A, their computer interface.  DOH!  Researching online, it doesn't work with the libraries for the TW523 and PSC05 stuff.  They don't sell those two new any-longer (or are scalped really expensive) so I bought two of the rf transceivers to work with the CM17 thingie I have.

I have the cm17, just not the transceivers.

So, root cause is incorrect hardware.
