Hi all,
I am having trouble getting my SK9822 LED strip to light up correctly.
My setup is-
PC 5v 18A Power Supply
5M 60LED/M SK9822 LED Strip
Raspberry Pi 3 b+
HDMI video capture card
I have GPIO 10 connected to DI on the strip, and GPIO 11 connected to CI on the strip.
The LED lights are showing the rainbow effect, but they are flickering when the ground from the PSU to the Pi is not connected.
The rainbow effect doesn't show up at all when the ground it connected from the PSU to any of the ground pins on the Raspberry Pi.
I don't know what to do next.
