Function Documentation

InitMonotonic()

void hf_time::esp32::InitMonotonic ( )

inlinenoexcept

No-op on ESP-IDF: the high-resolution timer is started by the system bootstrap before app_main runs.

Provided so callers writing portable init code can keep a single call site regardless of target.

MonotonicUs()

std::uint64_t hf_time::esp32::MonotonicUs ( )

inlinenoexcept

Microseconds since boot from the hardware-backed timer.

esp_timer_get_time() returns int64_t but is documented to be non-negative once started; widening to uint64_t matches the unsigned arithmetic used at call sites (deltas, comparisons).

Safe from any task or ISR.
