NeoPixel dependency is too old to accept customized brightness values and correct RGB-settings

[oxivanisher]

I did a clean install of the wordclock software as documented in the readme. With the current master of the https://github.com/jgarff/rpi_ws281x library, the wordlock is not working And with the mentioned commit https://github.com/jgarff/rpi_ws281x/tree/2f9e03c45ba0964029204db565ad9d6233b3a1a6, I get the following warning:

Exception AttributeError: "'Adafruit_NeoPixel' object has no attribute '_leds'" in <bound method Adafruit_NeoPixel.__del__ of <neopixel.Adafruit_NeoPixel object at 0xb633f370>> ignored
WARNING: Your NeoPixel dependency is to old to accept customized brightness values and correct RGB-settings.

Do you have another commit with these features available which you know that it is running?

Hi @oxivanisher, do you have any further details, why the clock doesn't work with the current master from rpi_ws281x? Regards, Bernd

Yes, the error is the following:

I tried hacking around for some minutes, but since I have other problems with the project, I did not investigate it deeper at the moment. 😁

Sorry for all the issues. I will upload another Swiss German variant and .STL files to 3D print the base layer once I have my setup up and running. 👍

Just merged your pull request back. Great work, @oxivanisher I especially like the 3d printing part...!

Hi @oxivanisher, I recently setup another wordclock, but did not run into this issue.... Did you make you clock run meanwhile?

Please reooen, if the issue still exists.
