[McHUG] Success!!!

[Rich Mitchell]

Wow! a night of successes - although it appears that Pete's note was posted from oh-dark-thirty this morning.  If we get pictures I can post them on my old web site - But we do have mchug.org - maybe I should take steps to get that hosted.  

Steve, after your explanation of how the AVRDUDE tool should work, I tried it with my old code.  The steps being:
1) turn the Butterfly off
2) enter "make project" and wait for it to get to the period.
3) turn the Butterfly on
4) push and hold the joystick until AVRDUDE completes.

With no modification to code or makefile the Butterfly programmed.  Worked like a charm.  My success rate with this approach and AVRDUDE is 100%.  When I was using the load tool in AVR Studio it was 50%.  The first try rarely found the chip, but second almost always did.  This has great simplified and shortened the process of making a change to the code, compiling it and programming it into the Butterfly chip.  Now once I make a code change it's 3 simple commands:
1) make clean
2) make all
3) make program (using the 4 step approach above)

Your success with the Arduino chip is now making this simple process standard over our Atmel AVR programming.  GREAT STEP FORWARD!!

So far we have 3 of us signed up for Friday night - Steve, Pete and me (Cindy will be there too).
