Module neopixel_example::lib::neopixel

Welcome to the neopixel library source code!

• By: Jonathan Zurita

• Version: 0.1.0

What is the function of this library?

This library allows the user to call user-friendly functions in order to manipulate WS2812 neopixels.

IMPORTANT NOTES

Please edit the pub const variables as needed

• (e.g. change NUM_LEDS to 24 instead of default value of 8.)

Why do use a watchdog timer as an argument?

I decided to include a watchdog timer in order to protect against possible lockups in DMA transmission. Thankfully utilizing a WDT requires minimal overhead. :)
