Direction of counting pixels on rings

by geekguy on Mon Aug 12, 2019 8:20 pm

Hi,

I have two neopixel rings - 12 and 16 pixel sizes. These two rings count pixels in opposite directions. My 12 pixel ring goes clockwise, and my 16 pixel ring goes counter clockwise.

Was this intended?

It is not too difficult to change counting directions in code, but I find it odd that this is the case with these two rings.
Which way does the 24 and 60 pixel rings count pixels?

Not sure the reasoning for the differences in direction, but you can infer the direction by looking at the IN and OUT pins. The data will flow from the IN to the OUT. So that will let you know which direction the NeoPixels are arranged.
