WS2812B WS2812 not working #24

Closed KSALPJan closed 5 years ago

KSALPJan commented 5 years ago

Hi I'm trying to get the WS2812 with my Raspberry pi 3B+ working. But my Raspberry pi 3B+ preferes to respond with the following answer (from the octoprint.log):

2019-07-09 16:17:02,785 - octoprint.plugins.rgb_status - ERROR - ws2811_init failed with code -11 (Selected GPIO not possible) 2019-07-09 16:17:02,788 - octoprint.plugins.rgb_status - ERROR - Error running effect: The strip object does not exist. Did it fail to initialize? 2019-07-09 16:17:02,796 - octoprint.plugins.rgb_status - INFO - Starting Idle Effect 2019-07-09 16:17:02,802 - octoprint.plugins.rgb_status - ERROR - Error running effect: The strip object does not exist. Did it fail to initialize?

Points I've done: -enabled SPI -connected the data pin from the LED strip to pin number 10 (BCM) -connected the ground of the LED strip with the Ground of the Raspberry pi -the LEDs are powered by a seperate PSU

@KSALPJan did you solve problem?

I've figured out what is the problem. It's because the Octoprint doesn't run for sudo. I don't suggest doing this. Here's why: https://community.octoprint.org/t/starting-octoprint-with-sudo-as-root-tells-me-you-should-not-run-octoprint-as-root-why/230 You'd better use GPIO10 and control via SPI.
