Function Documentation

vsf_adc_init()

vsf_err_t vsf_adc_init	(	vsf_adc_t *	adc_ptr,
		vsf_adc_cfg_t *	cfg_ptr
	)

Initialize an ADC instance.

Parameters

[in]	adc_ptr	a pointer to structure vsf_adc_t
[in]	cfg_ptr	a pointer to structure vsf_adc_cfg_t

Returns

vsf_err_t: VSF_ERR_NONE if initialization successful, otherwise returns error code

Note

It is not necessary to call vsf_adc_fini() to deinitialize.

vsf_adc_init() should be called before any other ADC API except vsf_adc_capability().

vsf_adc_fini()

void vsf_adc_fini

(

vsf_adc_t *

adc_ptr

)

Finalize an ADC instance.

Parameters

[in]

adc_ptr

a pointer to structure vsf_adc_t

Returns

none

vsf_adc_enable()

fsm_rt_t vsf_adc_enable

(

vsf_adc_t *

adc_ptr

)

Enable an ADC instance.

Parameters

[in]

adc_ptr

a pointer to structure vsf_adc_t

Returns

fsm_rt_t: FSM_RT_CPL if ADC was enabled, FSM_RT_ON_GOING if ADC is still enabling

vsf_adc_disable()

fsm_rt_t vsf_adc_disable

(

vsf_adc_t *

adc_ptr

)

Disable an ADC instance.

Parameters

[in]

adc_ptr

a pointer to structure vsf_adc_t

Returns

fsm_rt_t: FSM_RT_CPL if ADC was disabled, FSM_RT_ON_GOING if ADC is still disabling

vsf_adc_irq_enable()

void vsf_adc_irq_enable	(	vsf_adc_t *	adc_ptr,
		vsf_adc_irq_mask_t	irq_mask
	)

Enable interrupt masks of ADC instance.

Parameters

[in]	adc_ptr	a pointer to structure vsf_adc_t
[in]	irq_mask	one or more values of enum vsf_adc_irq_mask_t

Returns

none

Note

All pending interrupts should be cleared before interrupts are enabled.

vsf_adc_irq_disable()

void vsf_adc_irq_disable	(	vsf_adc_t *	adc_ptr,
		vsf_adc_irq_mask_t	irq_mask
	)

(

vsf_adc_t *

adc_ptr

)

Get the status of ADC instance.

Parameters

[in]
