int32_t adc_async_init(
    struct adc_async_descriptor *const descr,
    void *const hw,
    uint8_t * channel_map,
    uint8_t channel_max,
    uint8_t channel_amount,
    struct adc_async_channel_descriptor *const descr_ch,
    void *const func
)

This function initializes the given ADC descriptor. It checks if the given hardware is not initialized and if the given hardware is permitted to be initialized.

Parameters

descr

Type: struct adc_async_descriptor Struct *const

An ADC descriptor to initialize

hw

Type: void *const

The pointer to hardware instance

channel_map

Type: uint8_t *

The pointer to ADC channel mapping

channel_max

Type: uint8_t

ADC enabled maximum channel number

channel_amount

Type: uint8_t

ADC enabled channel amount

descr_ch

Type: struct adc_async_channel_descriptor Struct *const

A buffer to keep all channel descriptor

func

Type: void *const

The pointer to as set of functions pointers

Returns

Type: int32_t

Initialization status.

-1

Passed parameters were invalid or an ADC is already initialized

0

The initialization is completed successfully
