Hi All, I have done lot of searching but did not get any clue on what the problem is. so here are the details of my setup: Board: RPi 1 (Model B Rev2) Distro: Raspbian latest LED Type: WS2812B Count: 186 Hyperion Configuration: // DEVICE CONFIGURATION "device" : { "name" : "backdrop", "type" : "ws281x", "leds" : 186, "colorOrder" : "grb", "dmanum" : 10, "gpio" : 18, "freq" : 800000, "pwmchannel" : 0 }, Spoiler: Hyperiond log Hyperion Ambilight Deamon (573) Version : V1.03.4 (brindosch-c750c41/dc6a602-1522918225 Build Time: Apr 5 2018 01:57:25 INFO: Selected configuration file: /etc/hyperion/hyperion-pwm.config.json HYPERION INFO: ColorTransform 'default' => [0; 185] HYPERION INFO: ColorCorrection 'default' => [0; 185] HYPERION INFO: ColorAdjustment 'default' => [0; 185] LEDDEVICE INFO: configuration: { "colorOrder" : "grb", "dmanum" : 10, "freq" : 800000, "gpio" : 18, "leds" : 186, "name" : "backdrop", "pwmchannel" : 0, "type" : "ws281x" } whiteAlgorithm :: INFO: Creating linear smoothing HYPERION (CS) INFO: Created linear-smoothing(interval_ms=50;settlingTime_ms=200;updateDelay=0 EFFECTENGINE INFO: 27 effects loaded from directory /usr/share/hyperion/effects EFFECTENGINE INFO: Initializing Python interpreter INFO: Hyperion started and initialised INFO: Boot sequence 'Rainbow swirl fast' EFFECTENGINE INFO: run effect Rainbow swirl fast on channel 0 BLACKBORDER INFO: threshold set to 0 (0) BLACKBORDER INFO: mode:default started INFO: Json server created and started on port 19444 INFO: Proto server created and started on port 19445 ^CINFO: Application closed with code 0 EFFECTENGINE INFO: Cleaning up Python interpreter Shutdown WS281x PWM and DMA channel Segmentation fault I get segmentation fault when I close the hyperiond application. LEDs are not showing anything. I tested LEDs individually with current setup using example python script available in rpi_ws281x and it works fine. So I believe my setup is ok RPi PWM <--> WS2812B But the same setup does not work with hyperion. No LED is glowing, moreover hyperion remote is also not working in this case. Guys I really need help as this is kind of my dream project. Please guide me to fix this issue. I am currently clueless on where to look for the problem.
there is no fix for that, this a bug in the driver and the development of hyperion has stopped now for 5 Months so dont expect this being fixed soon. You got the option to use other led or buy a arduino nano and power the led with that.
RPi issues with clockless LEDs. Your best bet would be to get the Arduino Nano or better yet get the ESP8266/ESP32 and make the LED setup wireless.
Do you mean: Create a hyperion server somewhere and send UDP packets to the ESP8266 which was fllashed with arduino sketch as described here:? https://hyperion-project.org/thread...tension-with-esp8266-esp32-for-hyperion.3004/
