I'm following the ambient light project by DrZzs on Youtube. I have the WS2812B strips applied the rear of the TV. All strips were applied observing the data flow direction as indicated on the strips. LED 1 is in he upper left. I have 84 on the top, 48 on each side and 85 on the bottom.
I'm powering all four strips from a 20A power supply.
I have all the capture HW installed and I can see my Roku idle screen in Hyperion's web page, so that much is working.
However, I cannot get Hyperion to light a single LED. If I unplug the pi and plug in an arduino with s test sketch on it, the LEDs light up, So it is clearly something with the pi and perhaps my selection of GPIO.
The video mentions GPIO18. I'm honestly not sure why I soldered to 12 instead of 18, but from what I've uncovered, 12 should work.
I'm also not running a level shifter as the information I've found indicated I did not need one.
Beyond indicating the GPIO in the instance is there anything else at the OS level I need to change? The process is running as root.
Happy to provide whatever I can in order to help resolve this.
Thank you in advance.
