Roku stick to 2:1 HDMI splitter (REI w/EDID), on HDMI to TV, the other HDMI to HDMI Video Capture (HDMI in and USB out), USB into Rasberry Pi B running HyperBian-lite.
The LED light strip (WS2812B) is connected to the Rasperry Pi +5 and ground and a second 5v supply is also powering the LED strip (with common ground). The LED strip data wire is connected to Raspberry Pi GPIO 18.
From my desktop, I log into the ip address of the RPi port 8090 and configure as follows:
Controller Type ws281x
LED Output ON
Max LED count 300
GPIO number 18
Hardware LED count 300
Enable USB capture
Video Capture device USB Video
USB Capture activated
Internet API Access activated
When I click the monitor icon at the top right of my screen, I see the actual content being displayed on the TV as well as the correct colors for the LED's around the screen. This "simulator" seams to indicate that the software is working but I have no activity on the LED strip.
I have also tried disconnecting all the source material and simply putting the software into a "continuous test" within the effects configurator just to see if I could get some LED's to light up but no joy.
Any ideas ???
