phungductung 0:8ede47d38d10 21 [..]
phungductung 0:8ede47d38d10 22 This section provides functions allowing to configure the NVIC interrupts (IRQ).
phungductung 0:8ede47d38d10 23 The Cortex-M4 exceptions are managed by CMSIS functions.

phungductung 0:8ede47d38d10 30
phungductung 0:8ede47d38d10 31 -@- When the NVIC_PRIORITYGROUP_0 is selected, IRQ preemption is no more possible.
phungductung 0:8ede47d38d10 32 The pending IRQ priority will be managed only by the sub priority.
phungductung 0:8ede47d38d10 33
phungductung 0:8ede47d38d10 34 -@- IRQ priority order (sorted by highest to lowest priority):
phungductung 0:8ede47d38d10 35 (+@) Lowest preemption priority
phungductung 0:8ede47d38d10 36 (+@) Lowest sub priority
phungductung 0:8ede47d38d10 37 (+@) Lowest hardware priority (IRQ number)

phungductung 0:8ede47d38d10 40 *** How to configure Systick using CORTEX HAL driver ***
phungductung 0:8ede47d38d10 41 ========================================================
phungductung 0:8ede47d38d10 42 [..]
phungductung 0:8ede47d38d10 43 Setup SysTick Timer for time base.
phungductung 0:8ede47d38d10 44
phungductung 0:8ede47d38d10 45 (+) The HAL_SYSTICK_Config() function calls the SysTick_Config() function which
phungductung 0:8ede47d38d10 46 is a CMSIS function that:
phungductung 0:8ede47d38d10 47 (++) Configures the SysTick Reload register with value passed as function parameter.
phungductung 0:8ede47d38d10 48 (++) Configures the SysTick IRQ priority to the lowest value (0x0F).
phungductung 0:8ede47d38d10 49 (++) Resets the SysTick Counter register.
phungductung 0:8ede47d38d10 50 (++) Configures the SysTick Counter clock source to be Core Clock Source (HCLK).
phungductung 0:8ede47d38d10 51 (++) Enables the SysTick Interrupt.
phungductung 0:8ede47d38d10 52 (++) Starts the SysTick Counter.
phungductung 0:8ede47d38d10 53
phungductung 0:8ede47d38d10 54 (+) You can change the SysTick Clock source to be HCLK_Div8 by calling the macro
phungductung 0:8ede47d38d10 55 __HAL_CORTEX_SYSTICKCLK_CONFIG(SYSTICK_CLKSOURCE_HCLK_DIV8) just after the
phungductung 0:8ede47d38d10 56 HAL_SYSTICK_Config() function call. The __HAL_CORTEX_SYSTICKCLK_CONFIG() macro is defined
phungductung 0:8ede47d38d10 57 inside the stm32f7xx_hal_cortex.h file.
phungductung 0:8ede47d38d10 58
phungductung 0:8ede47d38d10 59 (+) You can change the SysTick IRQ priority by calling the
phungductung 0:8ede47d38d10 60 HAL_NVIC_SetPriority(SysTick_IRQn,...) function just after the HAL_SYSTICK_Config() function
phungductung 0:8ede47d38d10 61 call. The HAL_NVIC_SetPriority() call the NVIC_SetPriority() function which is a CMSIS function.
phungductung 0:8ede47d38d10 62
phungductung 0:8ede47d38d10 63 (+) To adjust the SysTick time base, use the following formula:
phungductung 0:8ede47d38d10 64
phungductung 0:8ede47d38d10 65 Reload Value = SysTick Counter Clock (Hz) x Desired Time base (s)
phungductung 0:8ede47d38d10 66 (++) Reload Value is the parameter to be passed for HAL_SYSTICK_Config() function
phungductung 0:8ede47d38d10 67 (++) Reload Value should not exceed 0xFFFFFF
