I would like to find a piece of electronic equipment that I think the best description would be an electronic camshaft. In the old days a shaft was hooked to a piece of equipment that had several cams that made and broke switches at various points in a revolution.
I would like something very similar to that, only electronic, that could communicate with a computer to set the on and off degrees of each output, but would turn the outputs on and off autonomously, without having to go through the computer. That always takes too long. I'm looking for 500-600 Hz. ... you'd think that'd be slow and easy but it ain't so.
I'm thinking a 360 ° encoder hooked to a counter whose output was the address buss to a 360 X 16 bit memory.
The memory locations would have the ons and offs programmed into them by the computer and then the data buss could just turn 16 outputs on and off as the counter incremented and enabled each location. Seems to me the speed of that would be pretty much limited only by the IC's.
The closest thing I could find is THIS
It's very close, but there's not a lot of info here and they have not responded to inquiries. Also it seems a bit much for the application, but the diagram is exactly what I have in mind.
Actually, I think there should be something available at the level of a chip or just a few chips on a board, but I can't find it.
Any help ????
thanks
