I admired with your design about Télécommande secteur then I have a question can I use PT2262 encoder in the transmitter circuit instead of 12C508 and PT2272 decoder instead of 12C508 in the reciever circuit? then please let me know the modification !!!
There is an app note from Microchip for a 16F877 to X10 controller. The source code and schematic is on Microchips site under the App Notes section. Just look for X10
