8-bit Binary to 3 X 7-segment Display

Hello All,

Just wondering how I would be able to display the full 0-256 value of an 8-bit binary number in 3 7-segment displays. I understand slightly that I would have to convert the 8-bit number into BCD, then send that to a 7-segment display driver (3 of them, or one of them muxed to three and a clock of some kind)

Just wondering how I would go about this without using a microcontroller, as I want to do it with discrete components.

For the record, I simply want a 0-255 decimal reading off of an A/D converter.

Hello.

I did this a while ago. it is on here somewhere. I used an EPROM and a couple of other chips. I think it was four digits and 14 bit, but you can leave off a digit. I did the PCB and everything. If you can not find it, let me know. If you want an EPROM programmed for it, I can do that for you and send it off.

Yes I found it... I posted it on 05-08-2007, 01:30 PM. You should be able to find it.

I am trying to complete my SAP-1 with a nice 3 digit display of an 8 bit binary input. I have a 8051 microcontroller and a programmer
but no experience in programming a microcontroller.
Can you point me to the project that you posted that has something to do with this?

Thank you

Here and here are some discussions on the matter.
The conversion is not trivial.
