  1. Closed: pic based mains frequency meter

    I think you should search for a period meter rather then a frequency meter. However let see how a frequency meter works before.

    A frequency meter (doesn't matter if based on PIC or whatever)...

    Demo does include this feature.
    However you cant save your drawings.
    Demo version 6 is downloadable from Downloads section upon registration.

    Provided that you set gain for Bode frequency precisely and keep it stable with time and with temperature otherwise you will get big distrorsion or damping like waves. An AGC FET based is usually...

    Hi SphinX,

    It's all right, no winners no loosers. :)

    The problem here is (as you said), no modifications would required to bomba's code in normal conditions, because his code is nice.

    SphinX,

    As I said (and confirm) the problem will depend from frequency !

    I got your sample and I simulated again in 6.2 SP5 (I've both).

    In your sample you make use of 5MHz as a processor...

    The problem seems related to internal clock of PIC model.

    Try to set Processor Clock Frequency up to 7MHz.
    Obviosly change your #use delay(clock=20000000) into the relevant frequency. Your code...

    Well, interesting behaviour, though unrelated from resistor value.

    Though cannot fully explain myself, you may have relevant results is you modify code such that:
