Hello Barry,

Barry>>So, it seems, I'm foggy on the basic picture here. Can anyone give me a clue? I'd be happy to furnish source code or schematics, but am unsure of forum etiquette on this.<<

I do not know what your source code is like, but if you furnish it, folks can look at it.

Can you scope anything?

Can you be *sure* the switch is being recognized as being pressed?

Is the value of your Pot a big enough difference for you to *SEE* the time difference in the blinking lights?

Try turning on BOTH LED's for 2 seconds in the area that the switch is pressed. That way you can see both LED's stay on, and verify your program actually went into the "Switch" routine.

Try leaving one LED on and just blinking the other, to determine that the "POT" routine was entered.

These are ways to verify your program is acting like it is supposed to. If they don't... you have to find the problem *why* it is not entering the "Switch Routine" and/or Why it is not entering the "POT read" routine.
