Functions

HAL_StatusTypeDef HAL_RNG_Init (RNG_HandleTypeDef *hrng)
 Initializes the RNG peripheral and creates the associated handle.
HAL_StatusTypeDef HAL_RNG_DeInit (RNG_HandleTypeDef *hrng)
 DeInitializes the RNG peripheral.
__weak void HAL_RNG_MspInit (RNG_HandleTypeDef *hrng)
 Initializes the RNG MSP.
__weak void HAL_RNG_MspDeInit (RNG_HandleTypeDef *hrng)
 DeInitializes the RNG MSP.
HAL_StatusTypeDef HAL_RNG_GenerateRandomNumber (RNG_HandleTypeDef *hrng, uint32_t *random32bit)
 Generates a 32-bit random number.
HAL_StatusTypeDef HAL_RNG_GenerateRandomNumber_IT (RNG_HandleTypeDef *hrng)
 Generates a 32-bit random number in interrupt mode.
void HAL_RNG_IRQHandler (RNG_HandleTypeDef *hrng)
 Handles RNG interrupt request.
uint32_t HAL_RNG_GetRandomNumber (RNG_HandleTypeDef *hrng)
 Returns generated random number in polling mode (Obsolete) Use HAL_RNG_GenerateRandomNumber() API instead.
uint32_t HAL_RNG_GetRandomNumber_IT (RNG_HandleTypeDef *hrng)
 Returns a 32-bit random number with interrupt enabled (Obsolete), Use HAL_RNG_GenerateRandomNumber_IT() API instead.
uint32_t HAL_RNG_ReadLastRandomNumber (RNG_HandleTypeDef *hrng)
 Read latest generated random number.
__weak void HAL_RNG_ReadyDataCallback (RNG_HandleTypeDef *hrng, uint32_t random32bit)
 Data Ready callback in non-blocking mode.
__weak void HAL_RNG_ErrorCallback (RNG_HandleTypeDef *hrng)
 RNG error callbacks.
HAL_RNG_StateTypeDef HAL_RNG_GetState (RNG_HandleTypeDef *hrng)
 Returns the RNG state.

                     ##### How to use this driver #####
  ==============================================================================
  [..]
      The RNG HAL driver can be used as follows:

      (#) Enable the RNG controller clock using __HAL_RCC_RNG_CLK_ENABLE() macro 
          in HAL_RNG_MspInit().
      (#) Activate the RNG peripheral using HAL_RNG_Init() function.
      (#) Wait until the 32 bit Random Number Generator contains a valid 
          random data using (polling/interrupt) mode.   
      (#) Get the 32 bit random number using HAL_RNG_GenerateRandomNumber() function.
