The command system.backlight defines the device's backlight intensity level.
This command is often used when the device is connected to the battery power as there is a considerable consumption of battery when the backlight is set to 100%.
- level [integer]
Backlight level percentage.
- variablereturn [integer]
Variable that will store the return code, where:
- -1: Error when defining the new value
- 0: OK
In the example above, the command system.backlight is used to modify the backlight intensity level to 50%.
Since the return of the command is an integervariable, the command inttostring is used to convert and display the variable using the command display.
