I originally started the project with an rpi0w, however, last night I replaced my rpi0w with an rpi3 and started from scratch. Installed OSMC (2017-09-01), installed all of the updates I could get through My OSMC. Installed Hyperion fresh again and double checked for updates and the like. I am now using Hypercon 1.03.2, which was released today.
Here's what it looks like when I try to set it to the color red (255,0,0):
For the hardware, I am using 87 LEDs total (with no gaps), connected to a 5V, 8A power supply, and corners connected using 4 pin connector cables. All of the lights are being lit up. I am using a terminal block in between all of these connections to avoid soldering. I have plans to use an HDMI splitter + USB grabber later on, once I can get the basic set up working.
I have also attached the hyperion.config.json file as well. Can someone please advice me on what to try next?
