Did you look at page 15 of the User Guide (ug130). It explains how to drive the
digits by selecting one four digit lines (active low, 0 = selected), and driving the
character you want on the 7 segment lines and decimal point (also active
low, 0 = light the selected segment). To use more than one digit at a time you
need to time-division multiplex. To avoid smearing at high refresh rates, you
should shut off all segments before changing the digit select line.
