Member Function Documentation

◆ begin()

void LowPowerClass::begin ( )

Initialize the Low Power library.

This initializes RTC library, because this library uses the RTC library.

◆ sleep()

void LowPowerClass::sleep ( uint32_t seconds)

Sleep (yield) this thread.

Parameters
[in]seconds- the sleep period

Just call the system call of sleep()

◆ coldSleep()

void LowPowerClass::coldSleep ( uint32_t seconds)

Enter the cold sleep state during the specified seconds.

Parameters
[in]seconds- the period in cold sleep

◆ deepSleep()

void LowPowerClass::deepSleep ( uint32_t seconds)

Enter the deep sleep state during the specified seconds.

Parameters
[in]seconds- the period in deep sleep

◆ bootCause()

bootcause_e LowPowerClass::bootCause ( )

Get the boot cause.

Returns
a boot cause

◆ isEnabledBootCause() [1/2]

bool LowPowerClass::isEnabledBootCause ( bootcause_e bc)

Check if the specified cause is permitted or not.

Parameters
[in]bc- a boot cause
Returns
true if permitted, otherwise return false

◆ isEnabledBootCause() [2/2]

bool LowPowerClass::isEnabledBootCause ( uint8_t pin)

Check if the cause by the specified pin is permitted or not.

Parameters
[in]pin- a pin number
Returns
true if permitted, otherwise return false

◆ enableBootCause() [1/2]

void LowPowerClass::enableBootCause ( bootcause_e bc)

Enable the specified cause as the boot cause.

Parameters
[in]bc- a boot cause

◆ enableBootCause() [2/2]

void LowPowerClass::enableBootCause ( uint8_t pin)

Enable the cause by the specified pin as the boot cause.

Parameters
[in]pin- a pin number

◆ disableBootCause() [1/2]

void LowPowerClass::disableBootCause ( bootcause_e bc)

Disable the specified cause as the boot cause.

Parameters
[in]bc- a boot cause

◆ disableBootCause() [2/2]

void LowPowerClass::disableBootCause ( uint8_t pin)

Disable the cause by the specified pin as the boot cause.

Parameters
[in]pin- a pin number

◆ getWakeupPin()

uint8_t LowPowerClass::getWakeupPin ( bootcause_e bc)

Get a wakeup pin number from the boot cause.

Parameters
[in]bc- a boot cause
Returns
a pin number.

◆ clockMode()

void LowPowerClass::clockMode ( clockmode_e mode)

Set clock mode and change system clock dynamically.

Parameters
[in]mode- the clock mode

◆ getClockMode()

clockmode_e LowPowerClass::getClockMode ( )

Get clock mode.

Returns
the clock mode

◆ getVoltage()

int LowPowerClass::getVoltage ( void )

Get the sensed battery voltage on CXD5247.

Returns
sensed voltage [mV]

◆ getCurrent()

int LowPowerClass::getCurrent ( void )

Get the sensed battery current on CXD5247.

Returns
sensed current [mA]. Negative value means discharge.
Attention
The returned value isn't time-averaged and just instantaneous value. Therefore, you can not get the strict current consumption. Please use this value as a guide.
