solipsistnationIt's not a euphemism.
Anyone else out there who reads my random wibblings ever messed with an arduino?
I've got one and the pocket piano kit (which I BUILT and it WORKS) and I only ask because I want to nerd out with somebody about stuff. I found some weird behavior that happens when you try to, say, load 2K of carefully perl-script-produced wavetables into 1K of RAM and then try to play whatever random garbage actually ends up in there and how I think I'm going to have to use strange compiler flags to load them into program RAM (14K of that free, yeah!) and then various crunchy memcpy type things to get it out so I can play it back, because I guess you can't just go ahead and access stuff from program RAM like it's data...? I dunno. This is all reminding me of the Amiga Fast RAM/Chip RAM confusion. But hey, I made it make sounds. Whoo!
