Sorry newb so if this is already possible my bad. Looking to make segments that would be able to utilize LEDs out of order. Like LEDs 2,3,4,5,12,13,14,15 as a segment and 6,7,8,9,10,11,22,23,24 as segment and so on. Or any combination of LEDs into a segment. ---

There is code for a custom LED layout. Can’t recall where, though. ☹ ---
