Parameters
Description
Remembered
Default
This command sets the display [brightness]. If the remember function is
on, this command acts the same as ’Set and Save Brightness’.
Yes
255
This command sets and saves the display [brightness] as default.
Always
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 and temperature
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.
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.
NOTE
contrast settings will have the same single effect. Efectively, values 0 through 7, 8 through
15, and so on will result in the same setting.
