Hi, Patrice

The problem is Pulsin needs a leading and a falling edge to work ... so 0 and 100 % do not trigger it ...

the way is test your input as soon as pulsin sends a zero ... ( after timeout, tho )

suppose pulse High :

Code:
Pulsin Portpin, 1 , result

IF result = 0 THEN 
    IF PortPin THEN 
       LCDOUT $FE,2 " Pulse > 900 "
    ELSE
       LCDOUT $FE,2 " No Pulse "
    ENDIF
ENDIF
no need to tweak the Pulsin Command ... just use logics !
