Re: Can I do this with a uProcessor?


">
I agree that he really doesn't need scanning. If he was willing to
use double pole switches he could get the higher density without
scanning. If he uses a really good micro like an 8051, he can just
wire the switches straight to the ports as pull downs.


Wait a minute....

Is that to say that if i don't use an 8051 I won't be able to wire the
switches straight to the input ports? I was hoping to use the existing
momentary contact switches, connect them straight to the input ports, and
have the input port pulled to ground when I step on the switch, which would
activate that input.

I'm going to look over that wires and switches example you gave me Moose,
and try to make some sense of it (right now no light bulbs are going off),
but, as Graham mentioned, it is my first project with a micro, and I think
I'd be wise to go with a more simple arrangement like the Atmel micro he
suggested. I think this is going to take me a long time to get off the
ground as it is.

Thanks
