HAL_NVIC_SetPriority
Function name
void HAL_NVIC_SetPriority (IRQn_Type IRQn, uint32_t
PreemptPriority, uint32_t SubPriority)
Function description
Sets the priority of an interrupt.
Parameters
IRQn: External interrupt number. This parameter can be an
enumerator of IRQn_Type enumeration (For the complete
STM32 Devices IRQ Channels list, please refer to the
appropriate CMSIS device file (stm32f2xxxx.h))
PreemptPriority: The preemption priority for the IRQn
channel. This parameter can be a value between 0 and 15 A
lower priority value indicates a higher priority
SubPriority: the subpriority level for the IRQ channel. This
parameter can be a value between 0 and 15 A lower priority
value indicates a higher priority.
Return values
None:
HAL_NVIC_EnableIRQ
Function name
void HAL_NVIC_EnableIRQ (IRQn_Type IRQn)
Function description
Enables a device specific interrupt in the NVIC interrupt controller.
Parameters
IRQn: External interrupt number. This parameter can be an
enumerator of IRQn_Type enumeration (For the complete
STM32 Devices IRQ Channels list, please refer to the
appropriate CMSIS device file (stm32f2xxxx.h))
Return values
None:
Notes
To configure interrupts priority correctly, the
NVIC_PriorityGroupConfig() function should be called before.
HAL_NVIC_DisableIRQ
Function name
void HAL_NVIC_DisableIRQ (IRQn_Type IRQn)
Function description
Disables a device specific interrupt in the NVIC interrupt controller.
Parameters
IRQn: External interrupt number. This parameter can be an
enumerator of IRQn_Type enumeration (For the complete
STM32 Devices IRQ Channels list, please refer to the
appropriate CMSIS device file (stm32f2xxxx.h))
Return values
None:
HAL_NVIC_SystemReset
Function name
void HAL_NVIC_SystemReset (void )
Function description
Initiates a system reset request to reset the MCU.
Return values
None:
HAL_SYSTICK_Config
Function name
uint32_t HAL_SYSTICK_Config (uint32_t TicksNumb)
