Struct PpgReading 

pub struct PpgReading {
    pub index: u16,
    pub ppg_channel: usize,
    pub timestamp: f64,
    pub samples: Vec<u32>,
}

A PPG (photoplethysmography) reading from the optical heart-rate sensor.

Available on Muse 2 and Muse S only. Each notification carries 6 raw 24-bit samples at 64 Hz.

Fields

index: u16

Sequential packet index (wraps at 0xFFFF), same purpose as EegReading::index.

ppg_channel: usize

Optical channel:

• 0 = ambient (background light subtraction)
• 1 = infrared
• 2 = red

timestamp: f64

Wall-clock timestamp in milliseconds since Unix epoch for the first sample.

samples: Vec<u32>

Raw 24-bit ADC values (not scaled to physical units). 6 samples per notification at 64 Hz.
