Field Documentation
◆ backing_off
| bool t_led_sync_refinement::backing_off |
Whether we're currently trying to back off a lower blink duration.
◆ current_blink_duration_ns
| time_duration_ns t_led_sync_refinement::current_blink_duration_ns |
How long the LEDs blink for, each frame.
Referenced by change_good_cutoff(), and get_search_period_locked().
◆ current_blink_fudge_ns
| time_duration_ns t_led_sync_refinement::current_blink_fudge_ns |
The amount of fudge between the latency offset and the actual blink start time, in nanoseconds, so we can place the blink at the optimal time for the exposure.
◆ current_latency_offset_ns
| time_duration_ns t_led_sync_refinement::current_latency_offset_ns |
