Re: [avr-chat] Do people like the XMEGA?

[Rick Mann]

Thanks for the link, Eric. I think I'll use it.

Interestingly, TinyG deprecated their instructions for using avrdude to flash 
it, in favor of AVR Studio. Any idea why? I use OS X, and prefer to stick with 
native tools (CLI or GUI).

Now, if I could just find a matrix that describes the various XMEGA family 
IDs...
