Hello everyone,
I have some problems with my installation...
My led strip have no reaction, sometimes it lights up white, sometimes it doesn't even light up.
My hardware installation :
-RPI 4
-led Strip WS2812B (
-Alimentation 5v 10a for the led strip (
-Video capture (HDMI to USB) (
-splitter HDMI 4K 60Hz (
I have read on many tutorial that the led strip must be connected to RPI on GND pin (connected to Pin 9) and on GPIO18 for DI. But my led strip doesn't light up...
I have try to connect on a SPI pin (pin 19 GPIO10 - SPIO-MOSI) and with this configuration my led strip light up white only.
I have try many configuration of hyperion (change configuration of led strip, change video capture,...) but nothing works.
When I click on display pannel I view my TV screen and a good configuration of my led strip, but they are no adaptation of the color (excepted when I valide a change, the led strip light up in blue or green)
I have test my led strip (and his alimentation) with a arduino Uno and it works perfectly.
I have realy no more idea to solve that
Can you help me?
PS: sorry for my English, i speak french
