Member Function Documentation

◆ feedWatchdog()

void McuNRF51::feedWatchdog ( )

overridevirtual

Watchdog reset을 방지하기 위하여 watchdog에 신호를 줍니다.

Nol.A-SDK에서는 특정 태스크의 MCU 점유 시간이 길어지는 경우 watchdog reset이 발생합니다. 따라서 postTask(), Timer 등으로 실행되는 태스크의 실행시간은 가능한 짧아야 합니다. 하지만, 간혹 busy wait를 해야 하거나 blocking 함수로 인해 실행시간이 길어질 수 있습니다. 이 경우 태스크의 중간 중간마다 이 함수를 호출하여 watchdog reset이 발생하는 것을 방지할 수 있습니다.

Implements McuGeneric.

◆ getResetReason()

uint32_t McuNRF51::getResetReason ( )

마지막으로 리셋된 원인을 가져옵니다.

마지막으로 보드가 리셋된 원인을 반환합니다. 원인이 둘 이상인 경우, OR 된 값이 반환됩니다.

Returns

리셋 원인에 대한 자세한 정보는 Nordic Semiconductor의 nRF51 Series Reference Manual의 12. Power management (POWER) 를 참고하시기 바랍니다.

◆ getTimeSinceBoot()

void McuNRF51::getTimeSinceBoot ( struct timeval * tv )

overridevirtual

보드 부팅 이후부터 현재까지의 경과 시간을 구합니다.

Parameters

tv[out] 경과 시간이 반환될 timeval 포인터

Implements RTCCalendar.
