◆ NRFX_RNG_DEFAULT_CONFIG

#define NRFX_RNG_DEFAULT_CONFIG

Value:

{                                                                \
    .error_correction   = true,                                  \
    .interrupt_priority = NRFX_RNG_DEFAULT_CONFIG_IRQ_PRIORITY,  \
}

RNG default configuration. Basic usage:

nrfx_rng_config_t config = NRFX_RNG_DEFAULT_CONFIG;
if (nrfx_rng_init(&config, handler)
{ ...

This configuration sets up randon number generator with the following options:

error correction enabled

Function Documentation

◆ nrfx_rng_init()

int nrfx_rng_init	(	nrfx_rng_config_t const *	p_config,
		nrfx_rng_evt_handler_t	handler )

Function for initializing the nrfx_rng module.

Parameters

[in]	p_config	Pointer to the structure with the initial configuration.
[in]	handler	Event handler provided by the user. Must not be NULL.

Return values

0	Driver was successfully initialized.
-EALREADY	Driver was already initialized.

◆ nrfx_rng_init_check()

bool nrfx_rng_init_check ( void )

Function for checking if the RNG driver is initialized.

Return values

true	Driver is already initialized.
false	Driver is not initialized.

◆ nrfx_rng_start()

void nrfx_rng_start ( void )

Function for starting the generation of random values.

New data should be handled by handler passed to the nrfx_rng_init() function.

◆ nrfx_rng_stop()

void nrfx_rng_stop ( void )

Function for stopping the generation of random values.

Function disables interrupts in peripheral and stops the generation of new random values.
