Here the first part of the code:
/*
VERSION WITH 3x4 KEYPAD, not capacitive touch unit
Modified to use * and # in place of two buttons
d. bodnar revised 5-23-2016
To Do:
1. LCD to show Loco #, speed, direction L=5721 S=88 D=> 16 Characters
2. LCD line two Function display 0000 0000 0000 ?????
3. Left button calls up Menu
4. Right button used to change loco in focus
5. POT center = stop, CCW = reverse to max, CW = forward to max
