8.1.2 Set Contrast (254 80 [contrast])
0xFF (between 0 and 255). Lower values cause ’on’ elements in the display area to appear lighter, while
higher values cause ’on’ elements to appear darker.
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 the backlight is off.
8.1.3 Set Contrast and Save (254 145 [contrast])
it saves the contrast value in the memory of the module, whereas, the previous command only changes the
value for the duration of use.
8.1.4 Backlight On (254 66 [minutes])
backlight will remain on after receipt of the command). If [minutes] is zero (0), the backlight will remain on
indefinitely.
8.1.5 Backlight Off (254 70)
8.1.6 Set Backlight brightness (254 153 [brightness])
between 0x00 and 0xFF (between 0 and 255). Lower values will cause the backlight intensity to “dim”,
while higher values cause the backlight’s intensity to “brighten”.
8.1.7 Set Backlight brightness and save (254 152 [brightness])
is a value between 0x00 and 0xFF (between 0 and 255). Lower values will cause the backlight intensity to
“dim”, while higher values cause the backlight’s intensity to “brighten”. Once this command has been sent,
[brightness] will be set accordingly on additional power ups.
Matrix Orbital
This command sets the display’s contrast to [contrast], where [contrast] is a value between 0x00 and
Lighting conditions will affect the actual value used for optimal viewing. Individual display modules
This command works in exactly the same way as the "Set contrast" command. The only difference is
This command turns on the backlight for a time of [minutes] minutes. (This specifies how long the
This command turns the backlight of the display off.
This commands sets the display’s backlight brightness to [brightness], where [brightness] is a value
This commands sets the display’s backlight brightness to [brightness] and saves it, where [brightness]
NOTE Backlight is always on by default on power up.
