Hello@all The Multiplex Modul has an refresh problem. When I want to switch some LED one after the other and I use the Multiplex Modul then the Multiplex Modul switch all LED on but no one off. First when I change the input the Multiplex Modul show me the right LED-Picture.

Connect the output of the Counter to the second input of the Multiplex & see what happens!

Whoa... that's an old one!

The consensus was this is not a bug but the correct functioning of the primitive.

When the multiplex switches is does not send a trigger through the old connection and so the Int primitives hold the old value. But taking them out won't fix it either because your LEDs rely on a trigger to make them redraw to the correct input state. If you force a trigger from the index (or the button) to the Int or the LED you'll get the behaviour you're expecting.

As to why it's not a bug, read the discussion in the above thread.

Hi Peter,

some Hint's 4U:

Just connect the Trigger Button 2 all Led's and don't forget a Bool true 4 the Multiplexer...

Ah now! Thx@all Special thanks at oddson !!! 🙂 This was the essential hint. Now each of my LED Modules have a redraw Modul and the Trigerbutton Trigers each LED. Now it works fine. Now I think I've realy understand the Function of the Multiplex Modul and the Integer Data Componet.

Thx for helping@all ! 😀 Peter

PS: I think I must make a pause! I'm blind! I can't see any treads, no simple errors, nothing. Have anyone a white cane fore me? 😉
