Hello,

Is it a single display or are there more displays?
If there are more displays, they could be multiplexed.

Hello Bertus,
It's a single digital display, so it's not multiplexed (Reply #6)
thx 4 asking.

Now, being Friday afternoon i'll start playing around with this stuff.

 

The signals might be static or not (means the actual led segments may not always be on). how about removing the display and put your own in place that you drive with a small controller?

 

Why do we keep getting questions and answers when the problem is already solved?

The display is common cathode, not multiplexed. He is connecting to the digital outputs before the resistors, so the voltages will be 0V for ON 5V for OFF.

Program an E\EPROM......7 segment lines go to the address lines data lines then go to where ever. Or use a PAL.

That would be okay for a hardware only solution, but the OP is using an Arduino. It would be easier to put the look up table in a program.

 

lots of possibilities. for example, you can put light sensors on the segments and read them that way.

or use different gpio pins do that.

shift registers can be used as well.

all depends on how complex this is, and how intrusive do you want to be.
