Pretty wicked awesome, I must say! Interfacing to an fpu with a uc? That's awesome
Thanks! Effects using sin & cos gained the most. I did not have room to use lookup tables. I think some of the speed I gained was lost in arduino to fpu IO transfer time. I should have spent an extra $2 for an SRAM chip.
May I ask how you're doing graphics? Is it a sram and a ramdac or something? What chips are you using for that part?
Liked the music and of course the platform.
Overall I'm unsure about this one as most effects on screen are damn tiny and mostly pretty slow.

For the music
Cool platform and decent music, but what Shockwav3 said. The small effects window didn't bother me, but many of the fx looked way too slow. Would be best to stick to visuals that can run in one frame. Motivational thumb for the hardware :)
Nice ! The "screen-in-screen" does its job well...
Great! Would be cool to have the music in full versions and good quality :)
awesome :)
Very nice, and from your blog seems you've been working on this for a long time!
Nice!
Ok :)
it's so satisfacting to built a device and then to program a demo for it. and close to that experience is to watch others doing so if the result is nice like this one. good job.
what Shockwav3 & evil said.
Great.
good work
great work and nice effects :)
Nice music and interesting platform but there's no direction whatsoever. The parts simply start and stop abruptly without any attempt at smooth transitions. Also, the performance is poor. The effects are way too slow to be particularly exciting. This also seems to affect the the timing of the music, which I have never seen in a demo before and which should never happen because it's very distracting. The playback should be rock solid.
I would like to have thumbed this prod down but I'll leave it at a motivational piggy for now.

WE ALL GONNA DIE!
wow!
this is serizzl bizzl! this is hight-tech shit!
very sluggish effects in a tiny section of the screen..
would have thumbed up, if the effects would have been less pc/amiga-ish, but running at way more frames instead..

I remember this; it was very cool :)
Thumb up for building it yourself.
But.. using an external VGA controller + 2 sound generators and then obtaining such a low frame rate: LFT/Craft proved you can do better!

The tiny window and the extremly slow speed are indeed an issue - I guess that's the price you have to pay for generating 256 colour output using a standard uVGA adapter.
I suppose a 16MHz ATMEGA could do a lot better if doing something like 128 x 80 in 2/4 bit using a custom video output.
Still, it's nice to watch and i'll certainly look forward to your next demo!

Thumbs up for effort. I, too, wonder about the framerate; maybe 2K of RAM was the culprit?
the problem is pushing pixels to the external vga circuit.
the serial bus is too slow.
its still cool stuff.

source code with graphics and music in a zip file (223K)
Music:
beginning (FM)
middle (PSG)
end (FM)

rv6502: You are correct. The serial bus was the biggest bottleneck. That and I didn't use lookup tables for sin/cos.
sigflup: I used the following with the baseboard adapter for the video:

Very cool! Lovely range of effects too :)
