Function Documentation

APDS9930_handler()

FctERR APDS9930_handler

(

APDS9930_t *const

pCpnt

)

Handler for APDS9930 peripheral.

Weak Functions

APDS9930 handler may be user implemented to suit custom needs

Note

May be called periodically to handle APDS9930 tasks

Alternately may be called when event occurs on APDS9930 pin (or by calling APDS9930_handler_it instead)

Parameters

[in]

pCpnt

- Pointer to APDS9930 component

Returns

FctERR - error code

Here is the call graph for this function:

Here is the caller graph for this function:

APDS9930_handler_all()

FctERR APDS9930_handler_all

(

void

)

Handler for all APDS9930 peripherals.

Note

May be called periodically to handle all APDS9930 tasks

Returns

FctERR - error code

Here is the call graph for this function:

APDS9930_handler_it()

FctERR APDS9930_handler_it

(

APDS9930_t *const

pCpnt

)

Handler for APDS9930 peripheral GPIO interrupt.

Note

APDS9930_INT_GPIO_Init has to be called at init before using interrupt handler function

Weak Functions

APDS9930 GPIO interrupt handler may be user implemented to suit custom needs

Note

May be called periodically to handle APDS9930 tasks through interrupts

Parameters

[in]

pCpnt

- Pointer to APDS9930 component

Returns

FctERR - error code

APDS9930_handler_it_all()

FctERR APDS9930_handler_it_all

(

void

)

Handler for all APDS9930 peripherals GPIO interrupt.

Note

APDS9930_INT_GPIO_Init has to be called at init before using interrupt handler function

May be called periodically to handle all APDS9930 tasks

Returns

FctERR - error code

Here is the call graph for this function:

APDS9930_Init_Sequence()

FctERR APDS9930_Init_Sequence

(

APDS9930_t *const

pCpnt

)

Initialization Sequence for APDS9930 peripheral.

Weak Functions

APDS9930 Init sequence may be user implemented if custom initialization sequence needed

Parameters

[in]

pCpnt

- Pointer to APDS9930 component

Returns

FctERR - error code

Here is the call graph for this function:

Here is the caller graph for this function:

APDS9930_Set_LPC()

void APDS9930_Set_LPC

(

APDS9930_t *const

pCpnt

)

Set proper LPC value (Lux per Count)

Note

Should be called after Configuration change of Integration time or Gain

Parameters
