Neopixel with level shifter on pin 21 not working #69

Closed p8ght closed 4 years ago

p8ght commented 4 years ago

I am running Neopixels on Pin 21 (BCM21) using a level shifter. When starting octoprint with root ( ./octoprint --iknowwhatimdoing ) following shows up:

- octoprint.plugins.rgb_status - ERROR - ws2811_init failed with code -5 (mmap() failed)
- octoprint.plugins.rgb_status - ERROR - Error running effect: The strip object does not exist. Did it 
   fail to initialize?
- octoprint.plugins.rgb_status - INFO - Starting Disconnected Effect
- octoprint.plugins.rgb_status - ERROR - Error running effect: The strip object does not exist. Did it 
   fail to initialize?

-> Neopixels don't light up at all

(i am using a touchscreen which is using pin10 - spi)
