Simple functions to calculate medians from doubles.
#include "median.h"
#include <string.h>
// Storage for the input to the median filter.
double data[MEDIAN_FILTER_SIZE];
double median_data[MEDIAN_FILTER_SIZE];
// Pointer to the next element in the median filter. Not very safe programming!

Example for the ESPBackBone library I'm writing
#include <ESP32BackBone.h>
double value1(0.0);
double value2(0.0);
// Converts the voltage value to 0-100 (used in the display code)
double progress(double inValue)

const double MIN = 0.0;
const double MAX = 3.3;
