MAX30100 Library Beat Detection Values Calculation

[Fatihalparslan]

Hello i try to develop a heart beat detection function which measure from wrist for max30101. I saw your MAX30100 Beat Detector.h library could you send me your source document/tutorial which base of defines below

#define BEATDETECTOR_INIT_HOLDOFF 2000 // in ms, how long to wait before counting
#define BEATDETECTOR_MASKING_HOLDOFF 200 // in ms, non-retriggerable window after beat detection
#define BEATDETECTOR_BPFILTER_ALPHA 0.6 // EMA factor for the beat period value
#define BEATDETECTOR_MIN_THRESHOLD 20 // minimum threshold (filtered) value
#define BEATDETECTOR_MAX_THRESHOLD 800 // maximum threshold (filtered) value
#define BEATDETECTOR_STEP_RESILIENCY 20 // maximum negative jump that triggers the beat edge
#define BEATDETECTOR_THRESHOLD_FALLOFF_TARGET 0.3 // thr chasing factor of the max value when beat
#define BEATDETECTOR_THRESHOLD_DECAY_FACTOR 0.99 // thr chasing factor when no beat
#define BEATDETECTOR_INVALID_READOUT_DELAY 2000 // in ms, no-beat time to cause a reset
#define BEATDETECTOR_SAMPLES_PERIOD 10 // in ms, 1/Fs
