    Hi, Ioannis

    Halas, the Rx outputs do not work like that ... and there are many solutions ...

    1) classical output ... the signals come from a shift register, so, the second channel begins ~ 10 NANOseconds after channel 1 signal falls ...and so on. ( see 4017 Datasheet ...)

    2) µPoutput, here, channels can be outputted 2 per 2 or 3 per 3 ... sequence is i.e. ch1 + 5,ch 2+6, ch3+7, ch4+8 ... leading edge synchronized.

    3) and, for some others ( generally old PCM systems ...) Ch, 1,2,3,4,5,6 ...Ch 1,2,3,4,5,7 ...Ch 1,2,3,4,5,8 ...

    So, no universal output capture device possible ... you must know wich rx you will "sample" ...

    There's a thread about these days on RC Groups :

    The guy is from china ... "Shanghai fool" ...

    Why insist on using 32 Bits when you're not even able to deal with the first 8 ones ??? ehhhhhh ...

    IF there is the word "Problem" in your question ...
    certainly the answer is " RTFM " or " RTFDataSheet " !!!
