Automatically get the number of leds

stoneWeb opened this issue · comments

Is there a way to automatically get the number of leds without setting a const variable?
Because I want to be able to access different numbers of light strips without having to re-modify the code.

Sorry. There is not. NeoPixels have no notion of how many neighbors they have, or how many total pixels exist, etc.. They simply strip off the first chunk of data in the stream, use it for themselves, and pass everything else along.
