If sending more than 10 characters to be stored, add in a ~10ms per character delay. Predefined custom
characters can be used in the “Start up Screen” as well, by using 0x00 through 0x07 characters.
6.1.6 Set brightness (254 153 [brightness]) (R)
This command sets the display brightness to [brightness], where [brightness] is a value between 0x00
and 0xFF (between 0 and 255). The higher the number is, the brighter the display will appear.
6.1.7 Set brightness and save (254 152 [brightness]) (R)
This command works in exactly the same way as the “Set brightness” command. The only difference is
that it saves the brightness value in the non-volatile memory of the module, whereas the previous command
only changes the value until the next power down.
6.1.8 General Purpose Output Off (254 86 [gpo #])
This command turns OFF any of the general purpose outputs. [gpo #] is 1 to 7.
6.1.9 General Purpose Output On (254 87 [gpo #])
This command turns ON any of the general purpose outputs. [gpo #] is 1 to 7. ON means that the output
is pulled low (ground via 240ohms).
