Light_WS2812 library V2.0 – Part II: The Code

After investigating the timing of the WS2812 protocol in the previous part, the question is now how to use this knowledge for an optimized software implementation of a controller. An obvious approach would be to use an inner loop that uses a switch statement to branch into separate functions to emit either a “0” symbol or a “1” symbol. But as it is often, there is another solution that is both more elegant and more simple.
