How best to time a pin state for extended periods of time

[aratti]

If Time accuracy is not an issue then a simple routine like this should solve the problem:

Counter  Var WORD

Main:

IF Pin_1 = 0 then
PAUSE 1000  ' one second delay
Counter = Counter + 1
IF Counter >1800 then Output_3 = 1
ENDIF

IF Pin_1 = 1  and Counter > 1 then
IF Counter <= 120 then Output_1 = 1
IF Counter >120 and Conter <= 1200 then Outpt_2 = 1
IF Counter >1200 then Output_3 = 1
Counter = 0
ENDIF


GOTO Main

All the time your Pin_1 will go to zero the time check will be activated.
