I've been tinkering with hypercon since yesterday, using a Raspberry Pi 3b and WS2812B LEDs. I'm running an HDMI splitter to an AV converter to a USB Grabber to the Pi. The LED strip is connected to a 5V 20A external power supply, with ground running to the pi as well. Finally the Data cable is connected to GPIO 18 of the Pi. I'm using a fresh install of Raspbian stretch lite as of right now. I successfully tested the LEDs with strandtest.py, they work fine with exactly this setup. However, after creating my config.json, sending it to the Pi (seeing if it's there with " ls /etc/hyperion") and stopping and starting hyperion, nothing happens. This is the config.json : This is the Hyperion log : The thing that seems weird to me is the fact that the Pi had no problem controlling the LEDs with the external library. Any help is greatly appreciated. EDIT: Also the frame grabber is working withing Hypercon on PC, since i can take screenshots and also corrected the Crop values for the black borders.
