Question about pause command until a condition happens

Kenm5261

In my bs1 program, I want to pause or stop the program from looping for a 10 seconds unless an input comes on. If the input comes on i want to jump to a different routine. Can I do this??
Would it be easier to write a for loop with a counter that would check every second to see if the input has come on, then jump to the different routine?

Override:
LOW 6
Pause 10000
GOTO Main


This is the subroutine I have. I forgot that I have to check an input while its paused and if this input comes on i have to goto main. It can switch over in a second, it doesnt have to switch in a millisecond or anything.

Override:
LOW 6
FOR x = 1 to 10000
IF Input = True THEN GOTO Elsewhere
Next
GOTO Main

Elsewhere:

Perform "Different routine"

I don't know how long it would take the For Next loop to run, but this code will let you check for an input during your waiting period.

I'm not sure if this is what you're looking for but it should give you something to think about. You set a value in timer to the number of 0.1 second units you want to delay (if there is no input). The delay will happen unless the input is sensed -- the trick is that your input should be at least 100 ms long so that you can hit the input check.

Delay:
· IF timer = 0 THEN Delay_Exit···· ' exit if timer expired
··· PAUSE 100······················'·delay 0.1 sec
··· timer = timer - 1············· ' update timer
··· IF Override = No THEN Delay··· ' keep going unless override input active

Delay_Exit:
· RETURN
