Member Data Documentation

stream

lsl::stream_outlet trigger2lsl::trigger2lsl_rt_t::stream

private

Outlet stream.

rising_edge

const std::string trigger2lsl::trigger2lsl_rt_t::rising_edge

private

String to be sent when a rising edge is detected.

falling_edge

const std::string trigger2lsl::trigger2lsl_rt_t::falling_edge

private

String to be sent when a falling edge is detected.

threshold

const mha_real_t trigger2lsl::trigger2lsl_rt_t::threshold

private

Threshold for state transition.

channel

const int trigger2lsl::trigger2lsl_rt_t::channel

private

Channel number where to look for threshold crossings.

state

bool trigger2lsl::trigger2lsl_rt_t::state =false

private

Current state.

false means HIGH and true means LOW. LOW state means we are below the threshold, looking for rising edges, HIGH state means we are above, looking for falling edges.

sampling_rate

const mha_real_t trigger2lsl::trigger2lsl_rt_t::sampling_rate

private

Sampling rate of the input signal.

Needed for timestamp offeset correction

use_edge_position

const bool trigger2lsl::trigger2lsl_rt_t::use_edge_position =true

private

Flag wether to use the position of the edge within the signal block to correct the timestamp of the output marker.

min_debounce

const int trigger2lsl::trigger2lsl_rt_t::min_debounce

private

Minimum number of consecutive samples that need to cross the threshold to initiate a state transition.

debounce_counter

int trigger2lsl::trigger2lsl_rt_t::debounce_counter =0

private

Debounce counter.
