OSTimer

OSTimerSeconds

This class requires the definition of OS_INCLUDE_OSSCHEDULER_TIMERSECONDS.

For systems equipped with a Real Time Clock (and OS_INCLUDE_32KHZ_TIMER defined), this timer runs completely independently, even when the device is in sleep or deep sleep mode. For systems not equipped with a RTC (and OS_INCLUDE_32KHZ_TIMER not defined), this time is derived from the existing OSTimerTicks.
