NCA9595: Low-voltage 16-bit I²C and SMBus I/O expander

Function Documentation

NCA9595_handler()

FctERR NCA9595_handler

(

NCA9595_t *const

pCpnt

)

Handler for NCA9595 peripheral.

Weak Functions

NCA9595 handler may be user implemented to suit custom needs

Note

Handler for NCA9595 is made for example (as its implementation depends mostly on I/O used) Basically, gets inputs (if any declared) and write outputs to previously stored values (if any declared).

May be called periodically to handle NCA9595 tasks

Alternately may be called when event occurs on NCA9595 pin (or by calling NCA9595_handler_it instead)

Parameters

[in]

pCpnt

- Pointer to NCA9595 component

Returns

FctERR - error code

Here is the call graph for this function:

Here is the caller graph for this function:

NCA9595_handler_all()

FctERR NCA9595_handler_all

(

void

)

Handler for all NCA9595 peripherals.

Note

May be called periodically to handle all NCA9595 tasks

Returns

FctERR - error code

Here is the call graph for this function:

NCA9595_handler_it()

FctERR NCA9595_handler_it

(

NCA9595_t *const

pCpnt

)

Handler for NCA9595 peripheral GPIO interrupt.

Note

NCA9595_INT_GPIO_Init has to be called at init before using interrupt handler function

Weak Functions

NCA9595 GPIO interrupt handler may be user implemented to suit custom needs

Note

May be called periodically to handle NCA9595 tasks through interrupts

Parameters

[in]

pCpnt

- Pointer to NCA9595 component

Returns

FctERR - error code

Here is the call graph for this function:

Here is the caller graph for this function:

NCA9595_handler_it_all()

FctERR NCA9595_handler_it_all

(

void

)

Handler for all NCA9595 peripherals GPIO interrupt.

Note

NCA9595_INT_GPIO_Init has to be called at init before using interrupt handler function

May be called periodically to handle all NCA9595 tasks

Returns

FctERR - error code

Here is the call graph for this function:

NCA9595_Init_Sequence()

FctERR NCA9595_Init_Sequence

(

NCA9595_t *const

pCpnt

)

Initialization Sequence for NCA9595 peripheral.

Weak Functions

NCA9595 Init sequence may be user implemented if custom initialization sequence needed

Note

Weak does nothing (keeping all IOs as inputs). Can be implemented with required need for outputs and/or interrupt pin.

Parameters

[in]

pCpnt

- Pointer to NCA9595 component

Returns

FctERR - error code
