@par Example Description
|
|
|
|
Configuration of the RNG using the HAL API. This example uses the RNG to generate 32-bit long random numbers.
|
|
|
|
At the beginning of the main program the HAL_Init() function is called to reset
|
|
all the peripherals, initialize the Flash interface and the systick.
|
|
Then the SystemClock_Config() function is used to configure the system
|
|
clock (SYSCLK) to run at 180 MHz.
|
|
|
|
The RNG peripheral configuration is ensured by the HAL_RNG_Init() function.
|
|
The latter is calling the HAL_RNG_MspInit() function which implements
|
|
the configuration of the needed RNG resources according to the used hardware (CLOCK,
|
|
GPIO, DMA and NVIC). You may update this function to change RNG configuration.
|
|
|
|
After startup, user is asked to press Tamper push-button.
|
|
The 8-entry array aRandom32bit[] is filled up by 32-bit long random numbers
|
|
at each key press.
|
|
The Random numbers can be displayed on the debugger in aRandom32bit variable.
|
|
|
|
In case of error, LED3 is toggling at a frequency of 1Hz.
|
|
|
|
|
|
@note The connection of the LCD reset pin to a dedicated GPIO PK7 instead of the STM32F469 NRST pin may cause residual display on LCD with applications/examples that do not require display.
|
|
The LCD clear can be ensured by hardware through the boards power off/power on or by software calling the BSP_LCD_Reset() function.

@par Hardware and Software environment
|
|
|
|
- This example runs on STM32F469xx/STM32F479xx devices.
|
|
|
|
- This example has been tested and validated with STMicroelectronics STM32469I-EVAL RevC board and can be
|
|
easily tailored to any other supported device and development board.
|
|
|
|
@par How to use it ?
|
|
|
|
In order to make the program work, you must do the following:
|
|
- Open your preferred toolchain
|
|
- Rebuild all files and load your image into target memory
|
|
- Run the example
