I'm at a point where I have the averaged ADC code running.  I've
combined this in with my MIDI input & output drivers and created a
template that I can use for my other programs.  The template contains:

header files and information
MIDI input (polled or interrupt mode)
MIDI output (polled)
1 mS timestamp (interrupt)
Four sample averaged ADC inputs (interrupt or polled)
SpeakJet driver
Led hex display driver (since IDE debug does not work with interrupts)

In polled mode, the ADC average scans the four inputs and averages
the data over the past 4 samples.  Execution time is 600 uS.

In interrupt mode, I have a table to define what inputs are scanned
on each 1 mS interrupt.  The default table scans IN-1 every 2 mS,
IN-2 every 4 mS, and IN-3 and IN-4 every 8 mS.  Execution time is 200
uS every 1 mS timer interrupt.

This code replaces my MIDI INPUT & OUTPUT code although I have left
it in the MIDI folder.  This code is called DJB TEMPLATE and I
uploaded it to the code fragments folder (since it's just the
drivers).

For a sample program, I have included a MIDI In to Out and IN-x to
OUT-x pass through mode.  It took quite a bit of work to get the
MIDI-In interrupts working with the timer interrupts and not loosing
any data.  I found all sorts of peculiarities with the interrupt
processing that I won't go into details about.  I think I'm really
pushing the limits of interrupt processing in basic at this point.

Enjoy.
