Configuration:

1. In Pinout and configuration, in security > RNG Mode & Configuration, Mode should be activated.

Manual Code: 

In main.c file, we need to call function to get random number as shown below:

/* USER CODE BEGIN WHILE */


while (1)

{

HAL_RNG_GetRandomNumber(&hrng);

HAL_Delay(200);

/* USER CODE END WHILE */


/* USER CODE BEGIN 3 */
