Struct LowBatteryDetector 

pub struct LowBatteryDetector { /* private fields */ }

Tracks consecutive low-battery samples and emits a PowerIntent::PowerOff once the streak crosses the configured threshold while the device is not USB-powered.

Matches the Meshtastic behavior documented in docs/hardware/t1000e-hardware.md: the T1000-E has no confirmed hardware undervoltage cutoff, so firmware must protect the Li-ion cell by shutting down before the voltage falls too far below the OCV table’s 3.1 V floor.

Implementations

impl LowBatteryDetector

pub fn new(threshold_mv: u16, streak_required: u8) -> Self

Create a detector. threshold_mv is the floor (samples strictly below this count toward the streak); streak_required is the number of consecutive low samples while not USB-powered needed to fire.

pub fn t1000e_default() -> Self

Default per the T1000-E plan: 3.1 V floor, 10-sample streak.

pub fn observe( &mut self, sample_mv: u16, usb_powered: bool, ) -> Option<PowerIntent>

Feed one sample. Returns PowerIntent::PowerOff the first time the streak crosses the threshold; subsequent calls return None until reset is called. This lets the power task act on a single fire and ignore further samples while it tears down.

pub fn streak(&self) -> u8

Number of consecutive low-while-on-battery samples seen so far.

pub fn fired(&self) -> bool

True once the detector has fired and is suppressing further events.

pub fn reset(&mut self)

Re-arm the detector (clears the fired flag and the streak).
