so
GND to GND
DI to GPIO10
CI to GPIO11
right?
LEDs lassen sich nicht steuern.

Now I am pretty shure the LED stripe is broke.
All pins are connected right and die SPI output is working
And also the software is up to datejust bc I´m interrested: what do you do for a living? you know so lot about all this stuff xD

i am a technician overall in electronics and secure systems, but also work alot with software and hardware sollutions.
The Raspberry for me was a new platform when i was introduced by Hyperion, but i already knew some Linux OS
and played with that before.So i burried myself in it the same what i always do to get to bottom of things.
just alot interest a electronical background and perseverance -
sounds very nice
thank you so much for troubleshooting with me
I will get back here sometime next week, when the new LED stripe arrived -
Troubleshooting
Loopback test
This can be used to test SPI send and receive. Put a wire between MOSI and MISO. It does not test CE0 and CE1.wget https://raw.githubusercontent.…ntation/spi/spidev_test.c
gcc -o spidev_test spidev_test.c
./spidev_test -D /dev/spidev0.0

I have the same setup almost but i am running Rasbian Buster full with Hyperion.NG 2.1 as .deb package
did all the updates and upgrades
APA102 and WS2801 works out of the box on RPI3b, no resistors or Arduino or levelshifters needed.
I see it like this always; the less equipment you need the less can go broke or offlinesee you then

do you know what spi mode is
SPI mode is the kind of signal you just tested on the GPIO's, 0 is spi device0 > thats the first device output for SPI devices
you have also SPI 0.1 but that's almost never in use because default is 0 -

why did i have spi mode 4 and you had spi mode 0 ? -

True, but in this case the most important pice of equipment seems to be broke. Now it is just Ambi without light -

I have no clue maybe for max attempts or line of tested output

Hi
My LED and PSU arrived today. I am wiring everything up right now. I will send a picture when I´m done just to be sure it is correct -
Finally done with the wiring. Would be very nice if anyone could proof that its correct.

i would say; get the show on the road
