Post by thread:[pic]: X10 RF protocol and PIC, how to communicate

Hi, I would like to interface a PIC to an X10 ON/OFF module (I am in the UK), but I cannot find the codes or a timing chart to be sent to the transceiver of the X10? Has anyone achieved this? How reliable are X10 products? (lighting strikes to nearby land?) Finally are they a good product or due they cause a lot frustration in use? Thanks Gary -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY! [EE]:,[OT]: ->Other [BUY]:,[AD]: ->Ads

I ran across a web page describing it in some detail a few years ago, but failed to bookmark it. The closest I have is the firecracker (CM17A) protocol: http://www.ubasics.com/adam/electronics/cm17.shtml The two links on the page no longer work, though. I suspect a google search might find it, and the links may be useful if used in the wayback machine. I remember finding it after several hours of surfing and searching for CM17A related webpages. Good luck, let me know if you find it! -Adam Gary Baker wrote: {Quote hidden}>Hi, > >I would like to interface a PIC to an X10 ON/OFF module (I am in the UK), but I cannot find the codes or a timing chart to be sent to the transceiver of the X10? > >Has anyone achieved this? > >How reliable are X10 products?

Hi Gary, When you say interface a PIC to an X10 ON/OFF module, do you mean you want the PIC to transmit and control a transceiver like the TM751 / RR501? If that is the case, the writeup on the firecracker (CM17A), as pointed out by Adam would indeed be the right article. Dr. Edward Cheung also has a description of the X10 RF protocol on his site. I am attaching both articles here; a third, also very good article is at Dave Houston's site. I have been doing a lot of work on 240 volt 50 Hz X10 receivers, and would love to exchange notes with all the X10 fans on this list.
