One question, I am also dealing with x10 , I have the trouble with the detector of the presence of the 120khz , did you made some progress with it? Thanks a lot.

Finally worked!!!!
Well I tested with 16Mhz internal oscillator and timer2 was within the range, so for testing I will use the internal.
Now regarding the pwm duty with the suggested values provide ...

Thanks for the recomendation. I will first test with a dummy oscillator (high and low the pin 4.1us during 1ms) The main problem is to get 7.68 Mhz crystal oscillator. Thanks a lot for your help

Ok, then, I will review items remarked. Thanks a lot

Hi
I have been reading and testing for quite a while, but I did not manage to make it work.
