Hi all, I'm new here, great forum/software here! After some research I decided to buy components to build a HDMI source ambilight add-on for my TV. Had a PI 3 already, so bought the following: 5V 10A power supply HDMI Splitter HDMI2AV converter USB 2.0 video grabber (chip: UTV007) 5m 6 LED per meter WS2813 LED strip Level Shifter (3V to 5V) 74AHCT126 As you can see I want to drive the strip directly from the PI. Most projects use the WS2812B or earlier, but I wanted to have the advantages of the WS2813. They seemed to be interchangeable, but after some testing this does not seem to be the case entirely. Current setup: PI 3 with raspbian Strip cut a 188 leds PC (win10 HyperCon) > HDMI2AV > Grabber > PI Power supply > Level shifter / WS2813 (power on one side for now) PI GPIO18 > Level shifter Level shifter > WS2813 DI HyperCon: Results so far: Connection with PI is working Installed Hyperion on PI using HyperCon Without the level shifter I got some colors, but not the right ones and something that looks like the booteffect. With the level shifter I usually get "white" light with some colored leds and no boot effect. Can grab screen, seems OK. Current problems: Can't get any logical colors from the strip, tried different byte orders. Some leds are flickering. Can't get static color by use of color picker. Question: Is it possible to drive the WS2813 by using the Hyperion PWM driver? I did (eventually) read soms hints in a few threads stating the SPI driver should be used for the WS2318, is this true?
