Hi All,

I just read the message from William M. Smithers containing the
following note :

    (NOTE on A/D code and JW parts: cover the window
      with something opaque, as light throws off the calibration).

I have always wondered if not covering the window on a JW part with
some kind of a sticker, could affect any function of the PIC like for
example the onchip A/D circuit. during software development I always
leave the window of the PIC clear when testing the application (I hate
to remove the ever sticking adhesive from window everytime) .
Sometimes the uncovered PIC stays in the application for weeks under
daylight (or officelight) environments. I have never experienced
malfunctioning or strange behaviour.

Any ideas or experiences?

Bye,

Daniel...
