Hello @felmue

the Grove2Dupont Cables arrived today.
I tried it with your example and all LEDs can be addressed and light up.

Thank you very much for the great help!

I do have some additional questions about the Pb.Hub and the VH3.96 Module in combination with my project.
Should i open another thread for it?

Hello @felmue

thank you very much for the follow up and providing a UIFlow example.
I ordered a package of Grove2Dupont Cables and will try it out as soon as they arrive.

I will post an update, when the cables arrive and i figured out how to wire them up.

Thanks!

Hello @felmue

Using some other pins is a good idea, but i think this is far beyond my competence and knowledge about micro controllers.
So i have to think about another solution for building a quiz buzzer.

Thank you very much for your good help!

Hello @felmue

thats very unfortunate.

What i was trying to achieve, to build something like a quiz buzzer where two switches are connected and the faster person to trigger the switch lights up the corresponding RGB Strip.

Is it possible to daisy-chain another module like the buzzer unit or the VH3.96 Module after the two RGB-Strips?

Or do you have another idea how can i build such a quiz buzzer?

Sorry for the many questions. This is the first time i've played around with micro controllers.

Thanks for your help

Hello @felmue,

thanks for the fast reply!
I found the thread you linked, too.
Is there any update regarding the limitations of the Pb.Hub?
So to "fix" the problem, i need to get a Pb.Hub v1.0? Or are there any other solutions?
Is it possible to connect two RGB Strips without the Pb.Hub?

In your last post in the thread you linked the TypeC2Gove Unit. Did you get it working with this unit?

Thanks for your help

Hello everyone,

i recently bought a M5Stack Atom Lite with various additional Units.
Among other things i bought two RGB LED Strips with 15 LEDs each and a PbHub Unit v1.1.

What i tried was connecting the RGB Strip to the Pb.Hub and lighting up all 15 LEDs. But when i run the code only the first LED lights up (in the right color). All other LEDs stay off.

When connecting the RGB Strip directly to the Atom lite, everything works fine. The following pseudo code works as expected:

The following pseudo code only lights up the first LED (RGB Strip connected to the Pb.Hub):

Even addressing any other LED only lights up the first LED (RGB Strip connected to the Pb.Hub):

Sometimes (i dont know what code triggered it) the Atom lite stops working completely and is showing a red light. After that i need to reset it to try it again.

When i try to donwload the code to the Atom lite to try it with out being connected to my computer, it stills lights up only the first LED:

After this, when i try to reconnect it to the PC, it wont connect to the UIFlow IDE. The only solution is re-burning the firmware.

While searching for a solutionfor my problem i found this thread:
https://community.m5stack.com/topic/5787/pb-hub-and-rgb-unit

Maybe anyone can help me with my problem (and the problem might be me :) )

Thanks for your help
