Default looking to build or find inexpensive 3-digit 7-segment LED display


wrote in message
...
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.




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.

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

Is that a joke?

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

Because Jim and I are retarded *******s. Your definition sounds to close to
ANSI C definition. There are million ways to name a thing.

Because Jim and I are retarded *******s. Your definition sounds to close
to
ANSI C definition. There are million ways to name a thing.




I forgot to mention Michael A. TerribleIl, he's a super-retarded soldier who
went with the idiots to war, they claimed they did it for Iraq, then claimed
it's for us, then claimed it's for the world. It's funny to no end.

What does C have to do with ICs? As usual, one needs to spell out
everything.

An "application-specific IC" is no more an application-specific device than
blank sheets of paper and pile of pencils are a novel. They should actually
be called "application non-specific ICs".

"A" stands for "application-specific" dummy. No need to make it lenghty.
