Description This command setsthe display’scontrast to [contrast], where[contrast] is
a value between 0x00 and 0xFF (between 0 to 255). Lower values cause
‘on’ elements in the display area to appear lighter, while higher values
cause ‘on’ elements to appear darker. Lighting and temperature condi-
tions will affect the actual value used for optimal viewing. Individual
display modules will also differ slightly from each other in appearance.
In addition, values for optimal viewing while the display backlight is on
may differ from values used when backlight is off.
This command does not save the [contrast] value, and is lost after power
down; but this command has the option of remembering the settings
when issued with the Remember function ‘on’ . When this is the case,
this command is the same as the Set and Save Contrast command.
