Rick, That sounds unrelated. Most likely you have an intermittent short or broken wire (if normally closed, perhaps caused by temperature), or your door contact is causing a similar problem.
My problem isn't with bouncing inputs, it's that the device access is corrupted at high temperatures. Paul Rick Bolen(gm) wrote: > As an aside, I too use a Hobbyboards 8 Channel I/O (DS2408) board.
