[sdiy] Ang: Blacet miniwave

[Daniel Araya]

I built my own wavetable osc with displays for bank and wave using the HP 5082-7340 (http://www.decodesystems.com/hp5082-7300.html)
They are quite obsolete but you can find them as surplus. Check Google for 5082-7300 and 5082-7340.

Hi,
 
I'm building a blacet miniwave module and I thought it would be nice if
I had two seven segment led's (each reading 0 to F) to show the bank number
(1 to 16) and wave number (1 to 16), rather than the array of (2x) four
led's normally used, as decoding them is probably a bit too much of a challenge
to my counting skills. There are four data lines, so it would be easy to
get the displays to read from 0 to 10 using a 4511 BCD to hex decoder/driver,
however I need each dispaly to read up to 16 (F) in hex, is there an easy
one chip solution for this or is it more involved?

Other option (even better) would be to use two dual 7 segment displays,
but it could be tricky getting them to display 1 to 16 rather than 0 to
15. Any ideas most welcome.
 
This is my first posting to this (superb) list and in terms of skill level
I'm pretty near the bottom of the slope, so do keep replies nice and simple
please :-)
