„GUI” stands for “Graphical User Interface”. It offers the user to interact with a device or SW using graphical elements. These graphical elements can be action items like e.g. buttons or line edits or indication elements like e.g. a gauge or a blinking “lamp” on the screen.
When it comes to In-Vision LED Drivers, we refer to the GUI as our SW with graphical elements for controlling the LED Driver and reading measurement values from it. As this SW sends the corresponding USB commands in the background to the LED Driver, it is an ideal starting point for making first tests with an In-Vision Light Engine or simply controlling it for Lab tasks.
