Is there a method to have this setting persist through power on?
If I set an initial value the display will always set that value when it powers on.
If I don't set an initial value the display defaults to 0 brightness.
Attempting this:

Code: Select all

void SystemTagBacklightBrightnessLevel_ValueChange(System.Object sender, Neo.ApplicationFramework.Interfaces.Events.ValueChangedEventArgs e)
		{
			if(Globals.Tags.SystemTagBacklightBrightnessLevel.Value < 5){ Globals.Tags.SystemTagBacklightBrightnessLevel.SetAnalog(10);}
		}
Normally value change events are fired at least once on power up, however this doesn't appear to work either.

How do I have a brightness slider in my application whose value persists through a power cycle?

Just check the Non-Volatile check box on the SystemTagBacklightBrightnessLevel tag. That will cause the backlight to be persistent across reboots.

Note that the SystemTagBacklightBrightnessLevel and the "Show Backlight Settings" action do not play real well together, so you should use one or the other, but not both in your project.
