FOUND IT !
Creating a new folder in Explorer and pasting the file into it put it
on the navigation window.
Good thing you fixed the crystal. That was required to make it work
and too simple of a mistake.
A question is why the diode on MCLR ?
Another question is why all the shift registers to only light a few
LED's ? And why the transistor on the LED's ? The shift register
can handle 20mA in a drain mode, and each LED can be run at 10mA so
there are lots of unneeded parts. OR... more likely many more parts
that are not shown.
It seems the PIC could easily handle the 6 LED's shown, more easily
than the way shown. Really makes me think things are not shown.
I would think the LED's are 'typical' for stings of 8 or so, like bar
graphs.
Volume, antenna strneght, signal strength.... ?
Very interesting.
