* @brief CMSIS STM32F4xx Device Peripheral Access Layer Header File. |
|||
* |
|||
* The file is the unique include file that the application programmer |
|||
* is using in the C source code, usually in main.c. This file contains: |
|||
* - Configuration section that allows to select: |
|||
* - The STM32F4xx device used in the target application |
|||
* - To use or not the peripheral’s drivers in application code(i.e. |
|||
* code will be based on direct access to peripheral’s registers |
|||
* rather than drivers API), this option is controlled by |
|||
* "#define USE_HAL_DRIVER" |

* This file provides two functions and one global variable to be called from |

* user application: |
|||
* - SystemInit(): This function is called at startup just after reset and |
|||
* before branch to main program. This call is made inside |
|||
* the "startup_stm32f4xx.s" file. |
|||
* |
|||
* - SystemCoreClock variable: Contains the core clock (HCLK), it can be used |
|||
* by the user application to setup the SysTick |
|||
* timer or configure other parameters. |
|||
* |
|||
* - SystemCoreClockUpdate(): Updates the variable SystemCoreClock and must |
|||
* be called whenever the core clock is changed |
|||
* during program execution. |

* The SystemCoreClock variable contains the core clock (HCLK), it can |

* be used by the user application to setup the SysTick timer or configure |
|||
* other parameters. |
|||
* |
|||
* @note Each time the core clock (HCLK) changes, this function must be called |
|||
* to update SystemCoreClock variable value. Otherwise, any configuration |
|||
* based on this variable will be incorrect. |
|||
* |
|||
* @note - The system frequency computed by this function is not the real |
|||
* frequency in the chip. It is calculated based on the predefined |
|||
* constant and the selected clock source: |
|||
* |
|||
* - If SYSCLK source is HSI, SystemCoreClock will contain the HSI_VALUE(*) |
|||
* |
|||
* - If SYSCLK source is HSE, SystemCoreClock will contain the HSE_VALUE(**) |
|||
* |
|||
* - If SYSCLK source is PLL, SystemCoreClock will contain the HSE_VALUE(**) |
|||
* or HSI_VALUE(*) multiplied/divided by the PLL factors. |
|||
* |
|||
* (*) HSI_VALUE is a constant defined in stm32f4xx_hal_conf.h file (default value |
|||
* 16 MHz) but the real value may vary depending on the variations |
|||
* in voltage and temperature. |
|||
* |
|||
* (**) HSE_VALUE is a constant defined in stm32f4xx_hal_conf.h file (its value |
|||
* depends on the application requirements), user has to ensure that HSE_VALUE |
|||
* is same as the real frequency of the crystal used. Otherwise, this function |
|||
* may have wrong result. |

* - The result of this function could be not correct when using fractional |

* value for HSE crystal. |
