Member Function Documentation

adjust()

virtual Result< void > ersa::hal::IRtc::adjust ( const TimePoint &  time )

pure virtual

Write explicit calendar fields and report bus/chip failures.

Implemented in ersa::test::MockRtc.

diagnostics()

virtual RtcDiagnostics ersa::hal::IRtc::diagnostics ( )

inlinevirtual

Return best-effort chip status; generic implementations report current time only.

init()

virtual Result< void > ersa::hal::IRtc::init ( )

pure virtual

Initialize the chip/bus and verify that calendar reads are plausible.

Implemented in ersa::test::MockRtc.

isHealthy()

virtual bool ersa::hal::IRtc::isHealthy ( ) const

pure virtual

Report backend health; this does not guarantee the wall time is accurate.

Implemented in ersa::test::MockRtc.

now()

virtual TimePoint ersa::hal::IRtc::now ( )

pure virtual

Return a calendar snapshot; the implementation may derive epoch fields.

Implemented in ersa::test::MockRtc.

resync()

virtual void ersa::hal::IRtc::resync ( )

inlinevirtual

Force reconciliation with hardware after a wake where uptime paused.

setEpoch()

virtual Result< void > ersa::hal::IRtc::setEpoch ( uint32_t  epochSeconds )

pure virtual

Convert and write epoch seconds without exposing a chip-specific date type.

Implemented in ersa::test::MockRtc.
