sub routine question

[emmett brown]

Is there any way I can talk someone into integrating the above that Dwayne contributed into this working code? I've tried several ways and only complicate the errors. Tried the COUNT command but don't know how to make it integrate into it to go to the sub routine. The counter will work perfectly for what I need but I am not experienced enough with PBP to make this addition. Thanks again Emmett

From what i understand, you want to execute a Subroutine at every 15minutes right?

The only thing that spring to mind without adding extra hardware is a Timer interrupt.. or measure the mainloop time, execute it untill it reach the 15Minutes, then execute the Subroutine. Once you know the time of the main program, you just calculate the amount of time you'll have to repeat it.

If you don't know the time... you can even use a extra i/o and measure it with a scope or whatever else.

Snip
High ExtraI_O
'mainRoutine
Low ExtraI_O

Assuming you must loop 'x' time

Start:
    for Repeat=0 to x
        ' MainLoop
        Next

    'Do your Subroutine here
    GOTO Start

Yes every 15 minutes or so no matter what the time length for the main program. I see what you mean, if the main took longer to execute then the counter wouldn't decrease in the same amount of time. Either way would simply need to be adjusted after running the program an hour or so. I'm still lost as to how or where to plug it into my program though. Yes, It stinks that I am relatively new at this. Thanks again, Emmett

well the timer interrupt is still valid.

Is it going to be a battery powered device or you can access easy to the line AC signal?

If so you can use a Counter overflow Interrupt. OR, by what i feel of, the Darrel Taylor's Elapsed timer could be another solution.

It'll be battery powered

I believe I have it tackled Thanks so much for the invaluable input! Emmett

Yep, it works ! Thanks much to Dwayne and Mister E without which it wouldn't have happened. The best pic forum on the net! Emmett
