RNG on BCM20736S

[SaCo_2181666]

Hi all,

Does BCM20736S support a Random Number Generator? If so, which Wiced API can be used to create a random number?

Regards,

Hi Sabino,

Please check if this will be helpful:

Does the 20736 have a "hardware" random number generator?

Re: how to get a random number with the sdk?

Hi AnjanaM_61​

Thanks for your reply. Yes, I find your links useful.

Please, could you confirm that if I do:

UINT32 rand_nums[4];

ulp_rand(rand_num, 4);

this single call will generate 4 random UINT32 numbers at once?

Thanks,

Sabino

Hi SaCo_2181666​

I have seen the implementation only as below :

UINT32 rand1, rand2, init_value, toggle_value;

static ref_clock = 0;

ulp_rand(&rand1, 1);

ulp_rand(&rand2, 1);

Refer to example pwm_tones in WICED SMART ( /WICED-Smart-SDK/Apps/pwm_tones )

Not sure if any other value to the second parameter works .

Thanks,

Anjana
