    Wonderful!!It seems very simple of the way that you indicate to me. I have proven it and works perfectly. The only problem that I see is that to very low frecuency (< 1Hz ) it value is erroneous and to high frequencies (> 1 kHz) the read value is erroneous too.

    Code:
    pulsHi var word
pulsLo var word
Time var word


MeasLoop:

Pulsin PortB.0,1,PulsHi
RCTime PortB.0,0,Pulslo

Time = PulsHi+PulsLo

LCDOut $FE,1, dec Time ' etc,etc ...

Goto measLoop
    Thank you very very much Alain!!!!
