Parameters
This command sets the display’s contrast 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 conditions 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.
NOTE This command saves the [contrast] value so that it is not lost after power down.
