1) Use your calculator in Windows, Programmer Mode (alt-3).
2) Assure you have "Dec" radio button selected.
3) Type in your integer for the appropriate number on LCD
4) Select "Bin" radio button, you'll get 0 and 1 output.
5) Match that output to the segments
6) Repeat at 2 until done
It's best to start with numbers which have less segments used (start with 1 (2 segs), 7 (3 segs). The rest is a process of elimination.
