mwf_periph_rng - TRNG

mwf_periph_rng - TRNG

This implements the_rng, a peripheral object that summarizes the procedures for using the chip’s built-in random number generation hardware.

With TWENET, this is used implicitly, so no initialization procedure is required in the user’s program.

Code example

if (!mwf::the_rng) {
    mwf::rng::global_init_rng_manager();
    mwf::the_rng->init();
}

uint32_t val = mwf::the_rng->random();

class mwf::periph::rng

global_init_rng_manager(), global_deinit_rng_manager()

static void global_init_rng_manager();
static void global_deinit_rng_manager();

These functions create and destroy the the_rng class object. The class object is automatically initialized upon creation, and random values can then be obtained.

random()

uint32_t random()

Returns a random value.

class mwf::periph::rng (sys_ev_handler)

on_sleep()

Performs the TRNG stop procedure.

on_wakeup()

Performs the TRNG startup procedure.
