"Smart" LED display
"Smart" LED display
(OP)
Ok I have several displays, very similar physically to regualar 7-segment displays. Can see a vague outline of a figure 8, and looks like a microproccessor is embedded in it.
I have been trying and trying and can't seem to figure it out.
the part number is Dialco 745-0007 and closest I could find on a datasheet was at http://www.americanmicrosemi.com/products/specs/745-0007.phtml
The goal is to use 2 of them as a hex output to a 90S2313 project. Looong story. And I know I could use traditional 7 segment displays for just hex, but wanted the "cool factor". I know one thing, this smart display is smarter than me.
Anyone ever ran into such a beast?

RE: "Smart" LED display
If you don't have the pinout, don't lose your time on it. (try to sell them instead) Did you ask a pinout to AMS? Instead, get a seven-segment display, with larger segments, and use a CD4511 to perform a similar functionality.
And if you have a microcontroller driving your display, do the seven segment conversion in software and use an octal latch to drive the segments.

I didn't bother to look up how expensive they were, we bought a surplus of components and had a few dozen of these in it, figured would put em to some use. :)
Now what to do with 3000 green leds.. hmmmm haha
Thanks again
