Detailed Description

Gate input with Schmitt trigger hysteresis and edge detection.

Note

All public methods are ISR-safe — pure state machine with no hardware I/O.

Member Function Documentation

falling()

bool sbl::components::cv::GateInput::falling ( )

inline

True if gate just went low (falling edge)

Consuming read — resets after first read. Call once per update cycle.

Definition at line 78 of file gate.hpp.

gate()

bool sbl::components::cv::GateInput::gate ( ) const

inline

Current gate state (true = high)

Definition at line 60 of file gate.hpp.

reset()

void sbl::components::cv::GateInput::reset ( )

inline

Reset all state.

Definition at line 85 of file gate.hpp.

rising()

bool sbl::components::cv::GateInput::rising ( )

inline

True if gate just went high (rising edge)

Consuming read — resets after first read. Call once per update cycle.

Definition at line 67 of file gate.hpp.

update()

void sbl::components::cv::GateInput::update ( uint16_t  raw )

inline

Feed a new raw ADC sample.

Schmitt trigger: gate turns ON when value >= threshold_high, turns OFF when value < threshold_low. The hysteresis band between the two thresholds prevents chatter.
