I confirm that this issue has not been resolved yet. Is there any news on this issue?

When you log-in into the rpi User Interface, you need to select an X11 based Window-Manager. Then you will be presented with the available Screengrabbers.
The current list is reduced, as Hyperion identifies that the other grabbers will not work how you currently use the system.
I have exactly the same problem and I don't know what to do. I am using the latest Raspberry Pi OS Bullseye. As far as I can see, it uses some kind of new window manager https://www.raspberrypi.com/ne…ry-pi-os-debian-bullseye/ Could you give more detailed instructions on how to get the screen capture to work? Additionally, I want to say that I use Kodi 19.3 on my Raspberry Pi 4 and would like to capture the screen from it.

Thanks a lot ReWiG. I much appreciate the quick response. PIN2 only seems to go into the level shifter but then nowhere from there. Is a wire missing in the diagram?
Thanks
Everything is as it should be -
Hi,
I'm pretty new to this but I followed the wiring diagram TPmodding posted for using one PSU to power strip and Pi4 and I got hyperion working. One thing I like to understand though is what is the connection between PIN1 and PIN4 for? What does it do and is it actually required for this setup?
Many thanks in advance!
This is completely unnecessary, it is enough to connect according to this scheme -
Did this fix the blinking issue as well? I am running ws2812 with addition of an arduino that blinks so am thinking about moving to this design.
yes, the flickering has stopped, it works! -
I've always installed hyperion via hypercon, but recently the rpi4 support has been removed from the installer.
I slightly modified the installation script to pass the processor check and hyperion on rpi4 works fine for me.
In the file https://github.com/hyperion-pr…r/bin/install_hyperion.sh
replace the line
with -
theoretically yes
Yes it works! Thank! I think this picture should be added to the wiki and the Raspberry Pi setup tutorial to close this issue permanently on this forum! -
you missed 3.3v on LV
And everything should work after that? -
it doesnt matter where your 5v comes..., you can use a second psu for that, but as i said, it is only important to have a common ground
At the moment, I have implemented a connection according to the following scheme:
But, either I soldered something wrong, or this circuit is wrong. The LED strip is not working.I see that it differs from your circuit in that the 5 volt power to the HV pin is supplied from the power supply, and not from the Raspbeerry Pi. It is fundamentally?
Do I understand correctly that my scheme should be like this?

at least you need one common ground connection between all psu
I see that this diagram uses a common power supply for the RPI and LED strip. But I want to reiterate that I have 2 separate power supplies. RPI is not powered via GPIO. I would like to get a schematic with this in mind, thanks.

I am using hyperyon.ng on my RPI4, but I have a problem, my APA102 LEDs blink randomly from time to time. I found information on this forum, this arises from the fact that the RPI GPIO pins give out 3.3 volts of voltage, and the APA102 LED strip accepts 5 volts. This can cause occasional outbreaks. I purchased a logic level converter like this to solve this problem
But I could not figure out how I should connect it to the power circuit. Most of the pictures describing its connection assume that the RPI and the LED strip will have the same power supply, but I don't need that. I want the RPI to have its own USB power supply and not depend on the LED strip power supply. At the moment I have connections according to this scheme:I would like to ask you to draw a diagram of how I should connect a logic level converter to this circuit so that everything works correctly and I have 2 power supplies, separately for the RPI and for the LED strip. Thank you in advance for your help!

My problem arises exactly when the power of the LED strip is off. Perhaps it is fed through CI and DI contacts, but how can I avoid this?
-
I use the APA102 LEDs together with RPI3.
I collected everything exactly according to the guide on this page https://hyperion-project.org/t…mbilight-no-soldering.77/Everything is working fine for me, no problems.
But when I turn off the power of the LED tape, then periodically, once in 1-2 minutes, random LEDs on my LED tape start flashing randomly. It is important that Raspberry Pi at this time remains on, 24/7.
What can I do with this? I do not want to turn off the power of Raspverry Pi, it's enough for me to turn off the power of the LED strip.
