Power Class

Namespace: GHIElectronics.TinyCLR.Native · Assembly: GHIElectronics.TinyCLR.Native

Power-management entry points: Reset for a soft reset, Sleep() for low-power stop with wake-up, Shutdown for power-off with RTC/pin wake-up, and SetSystemClock for dynamic clock scaling.

public static class Power

Methods

Reset()

public static void Reset()

Soft-resets the device, re-running the app afterward.

Sleep()

public static void Sleep()

Enters Sleep3 (deepest sleep). Wakes on any GPIO EXTI interrupt.

Sleep(DateTime wakeupTime)

public static void Sleep(DateTime wakeupTime)

Enters Sleep3 with an optional wake time. Pass DateTime.MaxValue for "pin only".

Parameter	Type	Description
wakeupTime	DateTime

Shutdown(int wakeupPins, DateTime wakeupTime)

public static void Shutdown(int wakeupPins, DateTime wakeupTime)

Powers off until either one of the selected wake-up pins asserts or the RTC alarm fires.

Parameter	Type	Description
wakeupPins	int	OR-combined wake-up pin bit mask. Each SoC's pin-package exposes a WakeupPin class (e.g. SC20260.WakeupPin.PA0) with one int constant per pin its hardware can wake on; OR them together to allow any of those pins to wake the device. Pass 0 for RTC-only wake. A bit not routed to this SoC's wake-up peripheral throws ArgumentException. Example: Power.Shutdown(SC20260.WakeupPin.PA0 | SC20260.WakeupPin.PA2, t).
wakeupTime	DateTime	Wall-clock time at which the RTC should wake the device, or DateTime.MaxValue for "pin only".

SetSystemClock(SystemClock clock, bool persist)

public static extern void SetSystemClock(SystemClock clock, bool persist)

Switches the core-clock profile. persist stores the choice across resets.

Parameter	Type	Description
clock	SystemClock
persist	bool

GetSystemClock()

public static extern SystemClock GetSystemClock()

Returns the current core-clock profile.

Returns SystemClock

Reset(bool runCoreAfter)

public static extern void Reset(bool runCoreAfter)

Soft-resets the device. When runCoreAfter is true, the app re-runs after reset; otherwise the device boots to bootloader.

Parameter	Type	Description
runCoreAfter	bool

GetResetSource()

public static extern ResetSource GetResetSource()

Returns the reason for the most recent reset.

Returns ResetSource

Fields

WakeupEdge

public static WakeupEdge WakeupEdge

Polarity used by Shutdown when waking from a pin event. Applies to every pin set in the wake-up bit mask.
