Hi, I am using a mobiflight variable to control display brightness. I am using a rotary encoder that is on the one hand controlling the "Main Panel Brightness" and a secondary input function is adding/subtracting from an internal variable which I then use in the "Brightness ref." in the "Display" section of the 7 seg LED display. Works great, but the value in the internal variable should only go from 0 to 15. Is there any way that this can be accomplished? e.g. an "IF" clause like "IF $<0:$=0 ELSE $-1"...

Or - easier path... - any way to read out the panel brightness setting in PMDG 737???

Never mind - I found a way to do it via FSUIP-PMDG - Event ID (mouse up/down)

Hi TheGerman,

Welcome to MobiFlight!

The behavior you describe is normal. You manipulate direct the MAX7219 and this ship can only be "dimmed in 16 steps (0 - 15).
That can be read in the data sheet what can be downloaded here: https://www.analog.com/media/en/technical-documentation/data-sheets/max7219-max7221.pdf

Hi....
Your basic idea was OK but as you find out its not logical ....

Your Panel Brightness must be sync with SIM Brightness.
So its not a good idea to handle 2 Systems with the Encoder simultary cause the MF Var and the Sim Bright are not sync.

Solution:

Way A .... Controll the Homecockpit Brightness by read the Sim Brightness ( What you cantroll by your Encoder)
Way B ... Set with the Encoder a Mobiflight Var that controll the Homecockpit Brightness (0-15) and also use THIS Var with a "Input Action" to controll the Sim Brightness.

So.... In easy words.
Controll both with one Encoder is correct... But not controll each individual... Controll just ONE and let the other controlled by the one you set already.
