Enumeration Type Documentation

ADS1115_func

enum ADS1115_func

Function enum for ADS1115.

Enumerator

ADS1115__FUNC_MULTIPLE_DIFF	Power-down single-shot mode.
ADS1115__FUNC_SINGLE_ENDED	Power-down single-shot mode.

Function Documentation

ADS1115_handler()

FctERR ADS1115_handler

(

ADS1115_t *const

pCpnt

)

Handler for ADS1115 peripheral.

Weak Functions

ADS1115 handler may be user implemented to suit custom needs

Note

May be called periodically to handle ADS1115 tasks

Alternately may be called when event occurs on ADS1115 pin (or by calling ADS1115_handler_it instead)

Parameters

[in]

pCpnt

- Pointer to ADS1115 component

Returns

FctERR - error code

!

Note

Conversion time need to be respected, ADS1115_handler_it may be used to handle GPIO pin interrupt, or ADS1115_Get_conv_ms may be used to help ensure that without using interrupt pin.

!

Note

If single shot is required, ADS1115_Start_NextConversion can be called once at init, using ADS1115_handler_it afterwards. ADS1115_handler shall be user implemented in this case, only to get converted value when interrupt pin triggers (and eventually start another conversion with ADS1115_Start_NextConversion).

Here is the caller graph for this function:

ADS1115_handler_all()

FctERR ADS1115_handler_all

(

void

)

Handler for all ADS1115 peripherals.

Note

May be called periodically to handle all ADS1115 tasks

Returns

FctERR - error code

Here is the call graph for this function:

ADS1115_handler_it()

FctERR ADS1115_handler_it

(

ADS1115_t *const

pCpnt

)

Handler for ADS1115 peripheral GPIO interrupt.

Note

ADS1115_RDY_GPIO_Init has to be called at init before using interrupt handler function

Weak Functions

ADS1115 GPIO interrupt handler may be user implemented to suit custom needs

Note

May be called periodically to handle ADS1115 tasks through interrupts

Parameters

[in]

pCpnt

- Pointer to ADS1115 component

Returns

FctERR - error code

Note

ADS1115_RDY_GPIO_Init has to be called at init before using interrupt handler function

May be called periodically to handle all ADS1115 tasks

Returns

FctERR - error code

Here is the call graph for this function:

ADS1115_Init_Sequence()

FctERR ADS1115_Init_Sequence

(

ADS1115_t *const

pCpnt

)

Initialization Sequence for ADS1115 peripheral.

Weak Functions

ADS1115 Init sequence may be user implemented if custom initialization sequence needed
