I was just saying that rather than that whole 555 timer circuit on the left-hand side, you can just plug in the system's clock (since it's pretty much fed to every controller known to man). Anyway, I've pretty much convinced myself that that sort of circuit probably wouldn't be the most reliable, since it might not even detect that there's a shift from low to high on the pin. Anyway, now that I understand your circuit, I commend you You have obviously given this about 100x more thought than I have.

Yeah, using the stock clock probably wouldn't work too well, esp. if you still have to use an AND gate at high enough frequencies to make it run hot.

Also, with multiplexing, the controller only samples each connection a fraction of the time, if I remember right, so clock speed-equivalent turbo would be too fast for the system to handle, and could easily cause problems.

Thanks for the compliment, BTW. ^^

This is pretty cool. I might have to try it out... It was a little confusing at first then I realized what the heck was going on. (I wasnt sure what the swiches were...)

They are each button's Turbo/Normal toggle.

Yeah.

I already knew what they did. That what I never understood, but I figured it out. Thanks for confirming it though.
