pulsin is not getting the next part of wave

[Ioannis]

With Pulsin the short answer is no.

Using the Timer 1 Gate will be much more easier ifyour PIC supports it.

Also controlling the Interrupt Edge on PB0 in combination with a timer (0 or 1) will also help you on this.

The edge is set in the Option Register, bit 6 on most PICs.

Did you try the snippet I posted in the first reply? I think it's pretty straight forward and I think it's pretty much the way that pulsin works "behind the scenes" except that doing this way "trigs" on level and not on transition.

If it doesn't work for whatever reason there are several other ways, some of which other members have outlined here but in order to be able to give you a good advice things like which chip you're using and at what frequency you're running it would be good to know. Not to mention what kind of resolution you actually NEED.

Hi,

Solution is pretty simple:

leader  var word
leader1 var word

Main:    
PULSIN GPIO.0,0,Leader  ' leader pulse is ~9mS low-going on port 0
   
IF Leader < 850  tHEN  main
  
RCTIME GPIO.0,1,Leader1      ' check for 1stkey seq only no repeat headers
    
if leader1 < 300 then Main  ' if high for < 300 (2.4ms then its the 2nkey)

may be you could consider the IF condition takes few µs ... to be verified, because your time unit is 10µs !

That's all !
