Ah so in memory you're treating LEDs as binary, either full on or full off? Are you handling any PWM for these LEDs in your code or is that ONLY for the strips? I presumed each channel would have variable levels of intensity but if you're going with off/on then I see where you're coming from.
I know what you mean about speed, that's why I said that it's good to have the flexibility there. I haven't used the strip in your example, the ones I have use a different chip, so I'm sure they're similar but non-identical.
I probably need to go back and re-read the whole 27 page thread, I like stuff like this. I'm not a huge pinball fan and am just getting back into upgrading my arcade cabinet, but some of the pinball cabs I've been seeing have got me interested... Just one arcade cab running mame and some console emulators and one well-made pinball table running a nice assortment of tables would make for a pretty sweet game room... I don't have a ton of space but could probably squeeze a table in (one of these days... after I knock out about a dozen other projects...)
