  PCF2111 LCD driver example code. Used with a dual-chip module (each chip
  drives 8 digits). Data and Clock lines are shared.
  This example code is written with portability in mind and can be used for PCF2111
  in any configuration. Future plans may be making a full ascii font (for this
  particular module).
  The code displays a scrolling message on the 16 digit 7 segment LCD.
  A hexadecimal font (for this particular segment setup) extended with
  several characters is included.
  
  segment map: A or B indicates A/B register
