Trying to initialize AllPixelMini using WS2812B. In initial test showed that RGB order needs adjustment. Used the following code:

import bibliopixel

causes frame timing information to be output

bibliopixel.log.setLogLevel(bibliopixel.log.DEBUG)

Load driver for the AllPixel

from bibliopixel.drivers.serial import *

set number of pixels & LED type here

driver = Serial(num = 10, ledtype = LEDTYPE.WS2812B, c_order = ChannelOrder.GRB)

Get the following error message:

Traceback (most recent call last):
File “.\biblioInitialTest.py”, line 8, in
driver = Serial(num = 10, ledtype = LEDTYPE.WS2812B, c_order = ChannelOrder.GRB)
NameError: name ‘ChannelOrder’ is not defined

You need to add from bibliopixel.drivers import ChannelOrder
Though, that’s also sort of the old way of doing things. Instead you can just do:

driver = Serial(num = 10, ledtype = "WS2812B", c_order = "GRB")

Then you don’t ever need to worry about importing those types.

I do, however, highly recommend using our Projects feature: https://github.com/ManiacalLabs/BiblioPixel/wiki/Projects
Then you don’t ever have to worry about imports at all. Everything is automatic.

Thanks for the quick and informative response. I am sure I will run into additional questions along the way, but this gets my LED project back on the road.
