I need to display the numbers 0-255 in decimal on a 3-digit LED
display for a microcontroller project (it would need to be visible in
the dark). Ideally the display would be inexpensive and not take up
too many uC outputs, but what I am finding is expensive ($30 or more).
Does anyone make an inexpensive 3-digit 7-segment LED module that
accepts serial input from say, a PICAXE or a BASIC Stamp 2? Also I
haven't done anything using serial i/o yet but I saw some displays
that had a "clock" pin (so the controller can sync up the data stream
with the module). Would I need to get a clock module for the basic
stamp to talk to the display module? What would a good one be? Can you
build a reliable clock for less using a 555 timer? I as thinking about
how such a device might work without a clock and thought of a way to
do it with 2 lines output, 0-0 would mean no data, 0-1 would mean here
comes some data, 1-0 would mean low, 1-1 would mean high. The display
module would consist of a microcontroller with 2 inputs and 12 outputs
(3 groups of 4 outputs going to a 7-segment encoder IC to drive each
digit). Is this a decent solution or unnecessary? Any advice or links
to a good example would be appreciated... Thanks.

You sure ask a lot of questions for someone from New Jersey.

Save your cash, forget electronic toys, you will be starved. Only buy what
you need. Take me for example, I am out of job, I have to post my fancy ad
at the bottom of my post every time. Go figure.

Analog/Mixed-Signal ASICK's and Discrete Systems

Is that a joke?

Why has no one ever pointed out that ASICs are actually AN-SICs?

Becasue ahe troll forging post as Jim thompson doesn't know what
you're talking about.
