Function Documentation

nrfx_err_t 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 initial configuration.
[in] handler Event handler provided by the user. Must not be NULL.
Return values
NRFX_SUCCESS Driver was successfully initialized.
NRFX_ERROR_ALREADY_INITIALIZED Driver was already initialized.
void nrfx_rng_start ( void )

Function for starting the random value generation.

Function enables interrupts in perihperal and start them.

void nrfx_rng_stop ( void )

Function for stoping the random value generation.

Function disables interrupts in perihperal and stop generation of new random values.
