Permission Denied ???

[Gnizten]

I´m abaut to install LED Status on klipper, i reached git clone [email protected]:11chrisadams11/Klipper-WS281x_LED_Status.git Cloning into 'Klipper-WS281x_LED_Status'...

I get this error.

Sorry, I added the incorrect command there. It should be git clone https://github.com/11chrisadams11/Klipper-WS281x_LED_Status.git to not require a key. I will get the readme updated. Thanks for pointing it out.

[Gnizten]

Thanks, that helped a lot for that matter, But now to the next challenge... :-)

Is the SPI interface enabled on your Pi? https://www.raspberrypi-spy.co.uk/2014/08/enabling-the-spi-interface-on-the-raspberry-pi/

I might need to add that to the instructions as well.

[Gnizten]

yes, Because i use SPI for my Accelerometer

[Gnizten]

I think its something related to permissions, because i can start manual with SUDO

[Paragaz]

I have the same problem. I can start it with sudo and without I got permission denied. The Status led started with sudo. I tried it with gpio 10 and 18 and there wasn't any difference.

If I use the macro buttons then I got this error

20:21:44 Command {status_led} finished 20:21:44 FileNotFoundError: [Errno 2] No such file or directory: 'settings_sample.conf' 20:21:44 run() File "/home/pi/Klipper-WS281x_LED_Status/klipper_ledstrip.py", line 35, in run settings = get_settings() File "/home/pi/Klipper-WS281x_LED_Status/klipper_ledstrip.py", line 27, in get_settings with open('settings_sample.conf', 'r') as sample_settings_file: 20:21:44 Traceback (most recent call last): File "/home/pi/Klipper-WS281x_LED_Status/klipper_ledstrip.py", line 18, in get_settings with open('settings.conf', 'r') as settings_file: FileNotFoundError: [Errno 2] No such file or directory: 'settings.conf'

During handling of the above exception, another exception occurred:

Traceback (most recent call last): File "/home/pi/Klipper-WS281x_LED_Status/klipper_ledstrip.py", line 167, in 20:21:44 Settings file (settings.conf) not found. Adding sample settings. 20:21:43 Running Command {status_led}...: 20:21:43 STATUS_LED

The setting.conf is in the same directory.

[Paragaz]

And per SSH i got this error

pi@raspberrypi:~/Klipper-WS281x_LED_Status $ ./klipper_ledstrip.py Can't open /dev/mem: Permission denied Traceback (most recent call last): File "/home/pi/Klipper-WS281x_LED_Status/./klipper_ledstrip.py", line 167, in run() File "/home/pi/Klipper-WS281x_LED_Status/./klipper_ledstrip.py", line 50, in run strip.begin() File "/usr/local/lib/python3.9/dist-packages/rpi_ws281x/rpi_ws281x.py", line 131, in begin raise RuntimeError('ws2811_init failed with code {0} ({1})'.format(resp, str_resp)) RuntimeError: ws2811_init failed with code -5 (mmap() failed) Segmentation fault

[Will-wastelander]

Can you confirm that you have the name of the files correct ? You say setting.conf is in the same directory, but the filename should be settings.conf.

And per SSH i got this error

Same issue for me running it on PIN 18

[11chrisadams11]

I believe that pin 10 is the only pin allowed to run without sudo. You could either run the script manually with sudo each time or modify the service to use the root user.
