Detailed Description

This file contains global variables.

Many of the variables in the NanoLux project are global. However, this means that thare are many variables defined that have limited use outside of a few files.

Variables that don't make sense to define in main.ino but are used globally should be first defined here.

Variable Documentation

◆ delt

double delt[SAMPLES]

Variable used to store the frequency delta between vReal and vRealHist.

◆ fbs

double fbs[5]

Global FIVE BAND SPLIT which stores changing bands based on raw frequencies
