Question - Prop2 Output Cycling?

[GregH]

Hi,

When I set the output to HIGH on any output pin, I notice that the voltage drops for a fraction of a second every 1 1/2 seconds.  Is this normal for the Prop2?  I can visually see the change in state using an LED. I get the same results on the PROP2 and the BS2 plugged into the Parallax BOE.  I'm using an output of the Prop2 to ground the POWER ON REQUEST of an ATX PC Power Supply.  Works but it shuts down the PS a few milliseconds  every 1 1/2 second (or so).

Thanks!

I've heard of something similar if you put an END at the end of your program. Can you post your program?

Shawn has it right: what you're probably seeing is the BS2's watchdog timer timing-out, which happens ever 2.3 seconds when your program lands on an END statement.  Change END to STOP to defeat this behavior.

Thanks Jon!

That did it.  I changed the END to STOP.

I just needed to hold an output high for testing and it was driving me nuts !

Thanks again!
