Dear customer,

I've checked with our Tools manager and our Marcom manager, and as long
as the ported code call attention to that this is ported Atmel code,
there are no other concerns from our side.

Good luck with your projects!

Best regards,

Øyvind Borgan

Problem : Copyright on Butterfly-Code
Hello   
I've ported the Butterfly-Code to GCC/avr-libc.Beside of the Sound/
"Music" it works like the original application. Most of the code 
is Atmel source-code (from the Application_Rev06 archive). There
are some copyright notes in the ATMEL-Code  (esp. in dataflash.h/
dataflash.c).
My questions: 
- Can I distribute the gcc-port or parts of it as open-source 
(free of charge)? (Possible distribution points: avrfreaks.com 
personal web-pages etc.)  
- Can I use parts of the code for own commercial projects? (Hard-
ware and Software) This includes selling firmware code that includes 
subroutines/modules that are based on the ATMEL-Butterfly-Code. 
Are there any concers from your side?  
Regards, Martin Thomas
