Enumeration Type Documentation

Enumerations for the possible microcontroller sleep modes.

  • SLEEPMODE_RUNNING Everything is active and running. In practice this mode is not used, but it is defined for completeness of information.
  • SLEEPMODE_IDLE Only the CPU is idled. The rest of the chip continues running normally. The chip will wake from any interrupt.
  • SLEEPMODE_WAKETIMER The sleep timer clock sources remain running. The RC is always running and the 32kHz XTAL depends on the board header. Wakeup is possible from both GPIO and the sleep timer. System time is maintained. The sleep timer is assumed to be configured properly for wake events.
  • SLEEPMODE_MAINTAINTIMER The sleep timer clock sources remain running. The RC is always running and the 32kHz XTAL depends on the board header. Wakeup is possible from only GPIO. System time is maintained. NOTE: This mode is not available on EM2XX chips.
  • SLEEPMODE_NOTIMER The sleep timer clock sources (both RC and XTAL) are turned off. Wakeup is possible from only GPIO. System time is lost.
  • SLEEPMODE_HIBERNATE This maps to EM4 Hibernate on the EFM32/EFR32 devices. RAM is not retained in SLEEPMODE_HIBERNATE so waking up from this sleepmode will behave like a reset. NOTE: This mode is only available on EFM32/EFR32

Function Documentation

RTCCRamData halAfterEM4 ( void )
void halBeforeEM4 ( uint32_t duration,
RTCCRamData input
)
void halCommonDelayMicroseconds ( uint16_t us )

Blocks the current thread of execution for the specified amount of time, in microseconds.

The function is implemented with cycle-counted busy loops and is intended to create the short delays required when interfacing with hardware peripherals.

The accuracy of the timing provided by this function is not specified, but a general rule is that when running off of a crystal oscillator it will be within 10us. If the micro is running off of another type of oscillator (e.g. RC) the timing accuracy will potentially be much worse.

Parameters
us The specified time, in microseconds. Values should be between 1 and 65535 microseconds.
void halCommonDisableVreg1v8 ( void )

Disable the 1.8V regulator. This function is to be used when the 1.8V supply is provided externally. Disabling the regulator saves current consumption. Disabling the regulator will cause ADC readings of external signals to be wrong. These exteranl signals include analog sources ADC0 thru ADC5 and VDD_PADS/4.

Note
: Only used when DISABLE_INTERNAL_1V8_REGULATOR is defined.
void halCommonEnableVreg1v8 ( void )

Enable the 1.8V regulator. Normally the 1.8V regulator is enabled out of reset. This function is only needed if the 1.8V regulator has been disabled and ADC conversions on external signals are needed. These exteranl signals include analog sources ADC0 thru ADC5 and VDD_PADS/4. The state of 1v8 survives deep sleep.

Note
: Only used when DISABLE_INTERNAL_1V8_REGULATOR is defined.
uint16_t halGetExtendedResetInfo ( void )

Returns the Extended Reset Cause information.

Returns
A 16-bit code identifying the base and extended cause of the reset
PGM_P halGetExtendedResetString ( void )

Calls halGetExtendedResetInfo() and supplies a string describing the extended cause of the reset. halGetResetString() should also be called to get the string for the base reset cause.

Application Usage:
Useful for diagnostic printing of text just after program initialization.
Returns
A pointer to a program space string.
bool halGetRadioHoldOff ( void )

Returns whether Radio HoldOff has been enabled or not.

Returns
true if Radio HoldOff has been enabled, false otherwise.
uint8_t halGetResetInfo ( void )

Gets information about what caused the microcontroller to reset.

Returns
A code identifying the cause of the reset.
PGM_P halGetResetString ( void )

Calls halGetResetInfo() and supplies a string describing it.

Application Usage:
Useful for diagnostic printing of text just after program initialization.
Returns
A pointer to a program space string.
void halInit ( void )

Initializes microcontroller-specific peripherals.

void halInternalDisableWatchDog ( uint8_t magicKey )

Disables the watchdog timer.

Note
To prevent the watchdog from being disabled accidentally, a magic key must be provided.
Parameters
magicKey A value ( MICRO_DISABLE_WATCH_DOG_KEY ) that enables the function.
void halInternalEnableWatchDog ( void )

Enables the watchdog timer.

void halInternalSysReset ( uint16_t extendedCause )

Records the specified reset cause then forces a reboot.

bool halInternalWatchDogEnabled ( void )

Determines whether the watchdog has been enabled or disabled.

Returns
A bool value indicating if the watchdog is current enabled.
void halPowerDown ( void )

Powers down microcontroller peripherals and board peripherals.

void halPowerUp ( void )

Powers up microcontroller peripherals and board peripherals.

void halRadioPowerDownHandler ( void )

Handler called in main context after radio has been powered off.

void halRadioPowerUpHandler ( void )

Handler called in main context prior to radio being powered on.

void halReboot ( void )

Restarts the microcontroller and therefore everything else.

void halResume ( void )

Resumes microcontroller peripherals and board peripherals.

EmberStatus halSetRadioHoldOff ( bool enable )

Enables or disables Radio HoldOff support.

Parameters
enable When true, configures ::RHO_GPIO in BOARD_HEADER as an input which, when asserted, will prevent the radio from transmitting. When false, configures ::RHO_GPIO for its original default purpose.
Returns
EMBER_SUCCESS if Radio HoldOff was configured as desired or EMBER_BAD_ARGUMENT if requesting it be enabled but RHO has not been configured by the BOARD_HEADER.
void halSleep ( SleepModes sleepMode )

Puts the microcontroller to sleep in a specified mode.

Note
This routine always enables interrupts.
Parameters
sleepMode A microcontroller sleep mode
See also
SleepModes
void halStackProcessBootCount ( void )

Called from emberInit and provides a means for the HAL to increment a boot counter, most commonly in non-volatile memory.

This is useful while debugging to determine the number of resets that might be seen over a period of time. Exposing this functionality allows the application to disable or alter processing of the boot counter if, for example, the application is expecting a lot of resets that could wear out non-volatile storage or some

EmberStack Usage:
Called from emberInit only as helpful debugging information. This should be left enabled by default, but this function can also be reduced to a simple return statement if boot counting is not desired.
void halStackRadio2PowerDownBoard ( void )

To assist with saving power when radio2 automatically powers down, this function allows the stack to tell the HAL to put pins specific to radio functionality in their powerdown state. The pin state used is the state used by halInternalPowerDownBoard, but applied only to the pins identified in the global variable gpioRadioPowerBoardMask. The stack will automatically call this function as needed, but it will only change GPIO state based on gpioRadioPowerBoardMask. Most commonly, the bits set in gpioRadioPowerBoardMask petain to using a Front End Module. This function is often called from interrupt context.

void halStackRadioPowerMainControl ( bool powerUp )

This function is called automatically by the stack prior to Radio power-up and after Radio power-down. It can be used to prepare for the radio being powered on and to clean up after it's been powered off. Unlike halStackRadioPowerUpBoard() and halStackRadioPowerDownBoard() , which can be called from interrupt context, this function is only called from main-line context.
