Macro Definition Documentation

◆ __ALIGN_END

#define __ALIGN_END

Definition at line 130 of file stm32f7xx_hal_def.h.

◆ __HAL_LINKDMA

#define __HAL_LINKDMA (   __HANDLE__,
  __PPP_DMA_FIELD__,
  __DMA_HANDLE__ 
)
Value:
do{ \
(__HANDLE__)->__PPP_DMA_FIELD__ = &(__DMA_HANDLE__); \
(__DMA_HANDLE__).Parent = (__HANDLE__); \
} while(0)

Definition at line 65 of file stm32f7xx_hal_def.h.

◆ __HAL_LOCK

#define __HAL_LOCK (   __HANDLE__)
Value:
do{ \
if((__HANDLE__)->Lock == HAL_LOCKED) \
{ \
return HAL_BUSY; \
} \
else \
{ \
(__HANDLE__)->Lock = HAL_LOCKED; \
} \
}while (0U)

Definition at line 92 of file stm32f7xx_hal_def.h.

◆ __HAL_RESET_HANDLE_STATE

#define __HAL_RESET_HANDLE_STATE (   __HANDLE__)    ((__HANDLE__)->State = 0U)

Reset the Handle's State field.

Parameters
<strong>HANDLE</strong>specifies the Peripheral Handle.
Note
This macro can be used for the following purpose:
  • When the Handle is declared as local variable; before passing it as parameter to HAL_PPP_Init() for the first time, it is mandatory to use this macro to set to 0 the Handle's "State" field. Otherwise, "State" field may have any random value and the first time the function HAL_PPP_Init() is called, the low level hardware initialization will be missed (i.e. HAL_PPP_MspInit() will not be executed).
  • When there is a need to reconfigure the low level hardware: instead of calling HAL_PPP_DeInit() then HAL_PPP_Init(), user can make a call to this macro then HAL_PPP_Init(). In this later function, when the Handle's "State" field is set to 0, it will execute the function HAL_PPP_MspInit() which will reconfigure the low level hardware.
Return values
None

Definition at line 86 of file stm32f7xx_hal_def.h.

◆ __HAL_UNLOCK

◆ HAL_IS_BIT_SET

#define HAL_IS_BIT_SET (   REG,
  BIT 
)    (((REG) & (BIT)) == (BIT))

Definition at line 62 of file stm32f7xx_hal_def.h.
