npr::rf::TdmSlotTimingController class final
#include <npr/phy/tdm_slot_timing_controller.hpp>

Minimal placeholder for TX timing preparation and TA lead mapping.

This intentionally avoids multi-loop control behavior. It only:

  • tracks basic timing diagnostics from observed TX events,
  • maps latest master TA sample to desired start-command lead.

The goal is a predictable baseline implementation while deeper TA control is redesigned.

Public functions

auto desired_start_cmd_lead_us() const -> int32_t
Returns desired negative offset between START_TX command issue time and slot target.
void on_master_ta_feedback(int16_t timing_advance_us, uint64_t now_us)
Applies master TA feedback sample to slowly correct desired start-command lead.
void on_tx_timing(uint64_t tx_call_us, uint64_t slot_alarm_us, uint64_t slot_target_us, uint64_t start_tx_cmd_us)
Updates controller with measured TX timing points from one slotted transmission.
void reset()
Resets controller state, adaptation gains, and accumulated diagnostics counters.
auto tx_prep_extra_us() const -> uint32_t
Returns additive preparation margin applied before slot alarm scheduling.
