Function Documentation

◆ ECAP_setEventPrescaler()

static void ECAP_setEventPrescaler	(	uint32_t	base,
		uint16_t	preScalerValue
	)

inlinestatic

Sets the input prescaler.

Parameters

base	is the base address of the ECAP module.
preScalerValue	is the pre scaler value for ECAP input

This function divides the ECAP input scaler. The pre scale value is doubled inside the module. For example a preScalerValue of 5 will divide the scaler by 10. Use a value of 1 to divide the pre scaler by 1. The value of preScalerValue should be less than ECAP_MAX_PRESCALER_VALUE.

Returns: None.

◆ ECAP_setEventPolarity()

static void ECAP_setEventPolarity	(	uint32_t	base,
		ECAP_Events	event,
		ECAP_EventPolarity	polarity
	)

inlinestatic

Sets the Capture event polarity.

Parameters

base	is the base address of the ECAP module.
event	is the event number.
polarity	is the polarity of the event.

This function sets the polarity of a given event. The value of event is between ECAP_EVENT_1 and ECAP_EVENT_4 inclusive corresponding to the four available events.For each event the polarity value determines the edge on which the capture is activated. For a rising edge use a polarity value of ECAP_EVNT_RISING_EDGE and for a falling edge use a polarity of ECAP_EVNT_FALLING_EDGE.

Returns: None.

◆ ECAP_setCaptureMode()

static void ECAP_setCaptureMode	(	uint32_t	base,
		ECAP_CaptureMode	mode,
		ECAP_Events	event
	)

inlinestatic

Sets the capture mode.

Parameters

base	is the base address of the ECAP module.
mode	is the capture mode.
event	is the event number at which the counter stops or wraps.

This function sets the eCAP module to a continuous or one-shot mode. The value of mode should be either ECAP_CONTINUOUS_CAPTURE_MODE or ECAP_ONE_SHOT_CAPTURE_MODE corresponding to continuous or one-shot mode respectively.

The value of event determines the event number at which the counter stops (in one-shot mode) or the counter wraps (in continuous mode). The value of event should be between ECAP_EVENT_1 and ECAP_EVENT_4 corresponding to the valid event numbers.

Returns: None.

◆ ECAP_reArm()

static void ECAP_reArm ( uint32_t base )

inlinestatic

Re-arms the eCAP module.

Parameters

base	is the base address of the ECAP module.

This function re-arms the eCAP module.

Returns: None.

static void ECAP_enableInterrupt	(	uint32_t	base,
		uint16_t	intFlags
	)

inlinestatic

Enables interrupt source.

Parameters

base	is the base address of the ECAP module.
intFlags	is the interrupt source to be enabled.

This function sets and enables eCAP interrupt source. The following are valid interrupt sources.

ECAP_ISR_SOURCE_CAPTURE_EVENT_1 - Event 1 generates interrupt
ECAP_ISR_SOURCE_CAPTURE_EVENT_2 - Event 2 generates interrupt
ECAP_ISR_SOURCE_CAPTURE_EVENT_3 - Event 3 generates interrupt

ECAP_ISR_SOURCE_COUNTER_OVERFLOW - Counter overflow generates interrupt
ECAP_ISR_SOURCE_COUNTER_PERIOD - Counter equal period generates interrupt
ECAP_ISR_SOURCE_COUNTER_COMPARE - Counter equal compare generates interrupt
ECAP_ISR_SOURCE_HR_ERROR - High resolution error generates interrupt

Returns: None.

◆ ECAP_disableInterrupt()

static void ECAP_disableInterrupt	(	uint32_t	base,
		uint16_t	intFlags
	)

inlinestatic

Disables interrupt source.

Parameters

base	is the base address of the ECAP module.
intFlags	is the interrupt source to be disabled.

This function clears and disables eCAP interrupt source. The following are valid interrupt sources.

ECAP_ISR_SOURCE_CAPTURE_EVENT_1 - Event 1 generates interrupt
ECAP_ISR_SOURCE_CAPTURE_EVENT_2 - Event 2 generates interrupt
ECAP_ISR_SOURCE_CAPTURE_EVENT_3 - Event 3 generates interrupt

ECAP_ISR_SOURCE_COUNTER_PERIOD - Counter equal period generates interrupt
ECAP_ISR_SOURCE_COUNTER_COMPARE - Counter equal compare generates interrupt
ECAP_ISR_SOURCE_HR_ERROR - High resolution error generates interrupt

Returns: None.

◆ ECAP_getInterruptSource()

static uint16_t ECAP_getInterruptSource ( uint32_t base )

inlinestatic

Returns the interrupt flag.

Parameters

base	is the base address of the ECAP module.

This function returns the eCAP interrupt flag. The following are valid interrupt sources corresponding to the eCAP interrupt flag.

Returns

Returns the eCAP interrupt that has occurred. The following are valid return values.

ECAP_ISR_SOURCE_CAPTURE_EVENT_1 - Event 1 generates interrupt
ECAP_ISR_SOURCE_CAPTURE_EVENT_2 - Event 2 generates interrupt
ECAP_ISR_SOURCE_CAPTURE_EVENT_3 - Event 3 generates interrupt
ECAP_ISR_SOURCE_CAPTURE_EVENT_4 - Event 4 generates interrupt
ECAP_ISR_SOURCE_COUNTER_OVERFLOW - Counter overflow generates interrupt
ECAP_ISR_SOURCE_COUNTER_PERIOD - Counter equal period generates interrupt
ECAP_ISR_SOURCE_COUNTER_COMPARE - Counter equal compare generates interrupt
ECAP_ISR_SOURCE_HR_ERROR - High resolution error generates interrupt

Note: - User can check if a combination of various interrupts have occurred by ORing the above return values.

◆ ECAP_getGlobalInterruptStatus()

static bool ECAP_getGlobalInterruptStatus ( uint32_t base )

inlinestatic

Returns the Global interrupt flag.

Parameters

base	is the base address of the ECAP module.

This function returns the eCAP Global interrupt flag.

Returns: Returns true if there is a global eCAP interrupt, false otherwise.
