Owner's manual

Description 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.

11.1 Introduction
Ensuring that your LK204-25-USB display’s exactly what you want it to can be the difference between a
projects success and failure. This is why we incorporate features such as Data Lock into the LK204-25-USB
With this new feature you now are in control over of how and when settings will be changed so there is no
need to worry about the module acting exactly like you expected it to because all the settings may be locked
and remembered for the next power up.
