I recently decided to start my first project with raspberry Pi and wanted to set up an ambilight system for my projector screen.
I have got mi RPi3 with hyperbian, WS2815 strip with common ground to the RPi3, and data wire into GPIO 18.
NONE of the LED turn on, not even from the android app.
However, when I tried changing from GPIO 18 to GPIO 10, I got the strip to light up, but only in bright white. When trying to change the color from the android app, the color (or the effect) changes for one second, and then turns back to bright white.
I tried running hyperion as root insitead of pi (I'm a beginner user so I'm not 100% sure I'm doing this the right way), and this didn't solve my problem.
I also tried putting the audio kernel module in the blacklist as stated here : https://github.com/jgarff/rpi_ws281x#pwm
But got no luck at all.
Could it be that I need a logic level converter?
Please help me I'm desperate, and sorry for my extreme ingorance, this is my first raspberry project.
