[McHUG] PICAXE Again

Sounds like you/re getting your Aspire One fully loaded with all your old 
stuff.  How is it working out so far?  I was checking them out on the 
internet.  What features do you have?  Hard drive or flash drive, three or 
six-cell battery, Linux or Windows, etc.

I was having trouble with the DDS60 shut down.  I wanted to use the 
power-down bit of the AD9851 to turn the DDS60 off and on for Morse.  After 
many Serial.print-s trying to troubleshoot code, I finally gave up and wrote 
a simple test program dedicated to the DDS60 alone.  Finally determined that 
when the AD9851 is powered-down using bit W34 of the serial word, the chip 
resorts back to parallel data input mode.  It has to be reset to serial data 
input mode before it can be turned back on.  This is not indicated on the 
AD9851 data sheet.  In fact, the discussion of the power down feature is in 
the serial data description section of the data sheet on page 16, and it 
mentions nothing about it dropping back into parallel mode.

I also discovered that the Arduino development system searches the 
sketchbook AND the libraries for .h and .cpp files.  I was using the Arduino 
editor to edit library files, saving as a sketch, and copying and pasting 
the text into a Notebook file and saving in the library area.  To compile 
the library, Arduino has to be exited and restarted.  It then reported 
duplicate definitions of functions, etc.  If you make simple changes in 
Notebook and resave, the old file in the Sketchbook and the updated file in 
the library are different and the compiler catches the differences, too.  I 
have been deleting duplicate library files in the Sketchbook so object files 
can be created in the hardware library section.  But, now I'm wondering if 
we could just make new libraries in the Sketchbook, say, have a Sketchbook 
subsection dedicated to libraries.  You then wouldn't have to keep copying 
and pasting and restarting. Something to try.

Hacking away.
