FMUL

As the French like to say Crikeys! It's been a long time since I posted. I thought once Anibit.com went live, I've be able to post to ByteCruft mroe often. That was the plan, at least.

I've been pretty much head-down, working on things related to Anibit. I think some more of it will be public soon.

So the title of this post, is my Public Service Announcement about ATtinys. FMUL is Atmel's assembly instruction for "unsigned fractional multiply". Before you make grandiose plans that hinge on doing fast math in hardware, make sure your CPU supports it. Most, if not all, ATtinys do not support hardware multiplication.
