Re: Basic Stamp 2 and SSC

How's this?
Try clocking the signals though programming. Put one Victor signal on the top of the first clock, then another on the top of the second, and so on. That is the only way I can think to get several Victors on a single signal pin. In short, do it in serial, as opposed to parallel, which is what you are doing.

The way to separate those signals is to syncronize a 5-stage Johnson counter with the FIRST controller. A 5-stage Johnson counter will take in a signal, send it out one output, then on the next clock, will send the next signal out to another output, and so on and so forth. It sounds like you want to use a serial system to control a normally-parallel system, so the johnson counter is required to separate the signals. It's the same system used by recievers, since the servo signals come from the transmitter in serial format, then is sent to the respective servo in parallel.
Hope this helps! It would be hard to program, but easy to do electrically. Using this particular system, you could control 4 or 5 Victors on a single pin. You could do 2 if you did a flip-flop based system.

I love to take things apart. The fact that they work better when I put them back together it just a bonus.
