your display is lot different.. http://www.gammon.com.au/forum/?id=11516
you have 8 pins on one side and 4 on the other where as i have 5 on one side and 6 on the other.. to me there is no comparison
all the tutorials i find are specifically for 4 digit and 8 digit and the pins are different so therefore they must be wired differently and so is the coding i'm sure.
is there a specific diagram for 3 digit 11 pin?
