I've been playing a bit with some AVR programming, using Atmel Studio 6, which IMHO is overbloated and slow.
So I thought: why not make AVR instruction macros and assemble with FASM?
After working on it for almost a week, I finished a more or less working version yesterday, only to find out about the existence of this new fasm g thing (actually been around for several months and I didn't notice) already with an AVR module

It's better than what I made in almost every aspect: generates hex output, mine only binary; optimizes jumps; is case insensitive. And error checking, mine mostly trusts the programmer

So duuuhh all this work almost for nothing.

But anyway, my version as a strong point: it accepts more flexible operand forms for adiw, sbiw and movw 16 bit instructions:



All these forms are synonymous, I copied this behavior from the AtmelStudio assembler.

So, now I go to read the manual for fasm g and leave you with my version of the AVR coding example from fasm g (using my fasm macros). I'm sure my macros have some bugs, so if anyone has some AVR code to test, I'll be thankful.

your code has fasm syntax, not fasmg

i have no m16 project, only m8/tn13/tn2313/tn26, but there is need to convert def files

Yes, I know. I guess I will just improve on the fasm g version when I understand the language.
