RNG driver¶
-
group
nrfx_rng Random Number Generator (RNG) peripheral driver.
Defines
-
NRFX_RNG_DEFAULT_CONFIG¶ 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
Typedefs
-
typedef void (*
nrfx_rng_evt_handler_t)(uint8_t rng_data)¶ RNG driver event handler type.
Functions
-
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
p_config – [in] Pointer to the structure with the initial configuration.
handler – [in] Event handler provided by the user. Must not be NULL.
- Returns NRFX_SUCCESS
Driver was successfully initialized.
- Returns NRFX_ERROR_ALREADY_INITIALIZED
Driver was already initialized.
-
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.
-
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.
-
void
nrfx_rng_uninit(void)¶ Function for uninitializing the nrfx_rng module.
-
struct
nrfx_rng_config_t¶ - #include <nrfx_rng.h>
Struct for RNG configuration.
