7 Segment Displays help

[Anthony Bates]

I'm currently working on retheming a Stern Nugent pin and I nearly have everything up and running to be able to dive deeper into writing the actual rules but I can't get my 7 segment displays to work. 

I am using LISY35 as the MPU and I have all of my coils, switches, and lamps mapped, and starting a test game, everything works great except the 7 segment displays. 

I tried referencing the section on the MPF website which says:

MPF can control all segment displays on your machine with LISY. Configure them like this:

segment_displays: info_display: number: 0 player1_display: number: 1 player2_display: number: 2 player3_display: number: 3 player4_display: number: 4

I've done this but it doesn't seem to be working. I've been through the main MPF tutorial as well as watched the video on segment displays but I still can't seem to get it working. 

Any help would be very appreciated as this seems to be my last hurdle in getting the software-hardware interface working. 

Thanks,

Anthony
