Function Documentation

nrfx_comp_ain_get()

NRFX_STATIC_INLINE nrf_comp_input_t nrfx_comp_ain_get

(

nrfx_analog_input_t

input

)

Function for getting the COMP input configuration for given generic analog input.

Parameters

[in]

input

The generic analog input to get the configuration for.

Returns

The COMP input configuration for the given analog input.

Note

The function takes into account the internal and external analog inputs. The function returns NRFX_COMP_INPUT_NOT_PRESENT for analog inputs that are not supported by the given device.

nrfx_comp_ext_ref_get()

NRFX_STATIC_INLINE nrf_comp_ext_ref_t nrfx_comp_ext_ref_get

(

nrfx_analog_input_t

input

)

Function for getting the COMP external reference input configuration for given generic analog input.

Parameters

[in]

input

The generic analog input to get the configuration for.

Returns

The COMP external reference input configuration for the given analog input.

Note

The function returns NRFX_COMP_INPUT_NOT_PRESENT for reference inputs that are not supported by the given device.
