Operation examples.
Example 1
Example 1 sets up the character a at Digit 0, b at Digit 1, c at Digit 2 and d at Digit 3. The
characters are initially set at full brightness (15/16 duty cycle) and displayed. The duty cycle is
then changed to half brightness (8/16 duty cycle) as the display is first blanked and then acti-
vated with the same a,b,c and d characters. The display is then flashed on and off by alternating
the BLANK and NORMAL commands before going to the STAND-BY Mode.
