Re: [avr-gcc-list] Const lookup table

[Sander Pool]

That's pretty slick. I'm thinking of using a mega128 to create sound (speech
to be exact) and I was thinking I could store quite a few small samples in
flash memory.

Does avrgcc take care of the 64 KB boundary automatically or do I need to
specify in which segment the tables go?

This is cool stuff! Of course I'd first have to make the m128 avrgcc work on
windoze :-)
