        .interrupt_priority = LPCOMP_CONFIG_IRQ_PRIORITY                           \
    }

LPCOMP driver default configuration, including the LPCOMP HAL configuration.

Typedef Documentation

typedef void(* lpcomp_events_handler_t)(nrf_lpcomp_event_t event)

LPCOMP event handler function type.

Parameters

[in]

event

LPCOMP event.

Function Documentation

void nrf_drv_lpcomp_disable

(

void

)

Function for disabling the LPCOMP peripheral.

Before calling this function, the driver must be initialized. This function disables the LPCOMP peripheral and its interrupts.

See Also

nrf_drv_lpcomp_enable()

void nrf_drv_lpcomp_enable

(

void

)

Function for enabling the LPCOMP peripheral and interrupts.

Before calling this function, the driver must be initialized. This function enables the LPCOMP peripheral and its interrupts.

nrf_drv_lpcomp_disable()

ret_code_t nrf_drv_lpcomp_init	(	const nrf_drv_lpcomp_config_t *	p_config,
		lpcomp_events_handler_t	events_handler
	)

Function for initializing the LCOMP driver.

This function initializes the LPCOMP driver, but does not enable the peripheral nor any interrupts. To start the driver, the function nrf_drv_lpcomp_enable() should be executed after initialization.

Note

Driver will be initialized to default settings if configuration struct is not provided.

Parameters

[in]	p_config	Initial configuration. Default configuration used if NULL.
[in]	events_handler	Handler function

Return values

NRF_ERROR_INVALID_PARAM	If the configuration is invalid.
NRF_ERROR_INVALID_STATE	If the driver has already been initialized.

void nrf_drv_lpcomp_uninit

(

void

)

Function for uninitializing the LCOMP driver.

This function uninitializes the LCOMP driver. The LPCOMP peripheral and its interrupts are disabled and local variables are cleaned. After this call, you must initialize the driver again by calling nrf_drv_lpcomp_init() if you want to use it.
