****************************************************************************** + @verbatim + ============================================================================== + ##### How to use this driver ##### + ============================================================================== + [..] + (#) Enable and configure the peripheral to be connected to the DMA Stream + (except for internal SRAM/FLASH memories: no initialization is + necessary) please refer to Reference manual for connection between peripherals + and DMA requests . + + (#) For a given Stream, program the required configuration through the following parameters: + Transfer Direction, Source and Destination data formats, + Circular, Normal or peripheral flow control mode, Stream Priority level, + Source and Destination Increment mode, FIFO mode and its Threshold (if needed), + Burst mode for Source and/or Destination (if needed) using HAL_DMA_Init() function. + + *** Polling mode IO operation *** + ================================= + [..] + (+) Use HAL_DMA_Start() to start DMA transfer after the configuration of Source + address and destination address and the Length of data to be transferred + (+) Use HAL_DMA_PollForTransfer() to poll for the end of current transfer, in this + case a fixed Timeout can be configured by User depending from his application. + + *** Interrupt mode IO operation *** + =================================== + [..] + (+) Configure the DMA interrupt priority using HAL_NVIC_SetPriority() + (+) Enable the DMA IRQ handler using HAL_NVIC_EnableIRQ() + (+) Use HAL_DMA_Start_IT() to start DMA transfer after the configuration of + Source address and destination address and the Length of data to be transferred. In this + case the DMA interrupt is configured + (+) Use HAL_DMA_IRQHandler() called under DMA_IRQHandler() Interrupt subroutine + (+) At the end of data transfer HAL_DMA_IRQHandler() function is executed and user can + add his own function by customization of function pointer XferCpltCallback and + XferErrorCallback (i.e a member of DMA handle structure). + [..] + (#) Use HAL_DMA_GetState() function to return the DMA state and HAL_DMA_GetError() in case of error + detection. + + (#) Use HAL_DMA_Abort() function to abort the current transfer + + -@- In Memory-to-Memory transfer mode, Circular mode is not allowed. + + -@- The FIFO is used mainly to reduce bus usage and to allow data packing/unpacking: it is + possible to set different Data Sizes for the Peripheral and the Memory (ie. you can set + Half-Word data size for the peripheral to access its data register and set Word data size + for the Memory to gain in access time. Each two half words will be packed and written in + a single access to a Word in the Memory). + + -@- When FIFO is disabled, it is not allowed to configure different Data Sizes for Source + and Destination. In this case the Peripheral Data Size will be applied to both Source + and Destination. + + *** DMA HAL driver macros list *** + ============================================= + [..] + Below the list of most used macros in DMA HAL driver. + + (+) __HAL_DMA_ENABLE: Enable the specified DMA Stream. + (+) __HAL_DMA_DISABLE: Disable the specified DMA Stream. + (+) __HAL_DMA_GET_FS: Return the current DMA Stream FIFO filled level. + (+) __HAL_DMA_ENABLE_IT: Enable the specified DMA Stream interrupts. + (+) __HAL_DMA_DISABLE_IT: Disable the specified DMA Stream interrupts. + (+) __HAL_DMA_GET_IT_SOURCE: Check whether the specified DMA Stream interrupt has occurred or not. + + [..] + (@) You can refer to the DMA HAL driver header file for more useful macros. + + @endverbatim + */ + +/* Includes ------------------------------------------------------------------*/ +#include "stm32h7xx_hal.h" + +/** @addtogroup STM32H7xx_HAL_Driver + * @{ + */ + +/** @defgroup DMA DMA + * @brief DMA HAL module driver + * @{ + */ + +#ifdef HAL_DMA_MODULE_ENABLED + +/* Private types -------------------------------------------------------------*/ +/** @addtogroup DMA_Private_Types + * @{ + */ +typedef struct +{ + __IO uint32_t ISR; /*!< DMA interrupt status register */ + __IO uint32_t Reserved0; + __IO uint32_t IFCR; /*!< DMA interrupt flag clear register */ +} DMA_Base_Registers; + +typedef struct +{ + __IO uint32_t ISR; /*!< BDMA interrupt status register */ + __IO uint32_t IFCR; /*!< BDMA interrupt flag clear register */ +} BDMA_Base_Registers; +/** + * @} + */ + +/* Private variables ---------------------------------------------------------*/ +/* Private constants ---------------------------------------------------------*/ +/** @addtogroup DMA_Private_Constants + * @{ + */ +#define HAL_TIMEOUT_DMA_ABORT (5U) /* 5 ms */ + +#define BDMA_PERIPH_TO_MEMORY (0x00000000U) /*!< Peripheral to memory direction */ +#define BDMA_MEMORY_TO_PERIPH ((uint32_t)BDMA_CCR_DIR) /*!< Memory to peripheral direction */ +#define BDMA_MEMORY_TO_MEMORY ((uint32_t)BDMA_CCR_MEM2MEM) /*!< Memory to memory direction */ + +/* DMA to BDMA conversion */ +#define DMA_TO_BDMA_DIRECTION(__DMA_DIRECTION__) (((__DMA_DIRECTION__) == DMA_MEMORY_TO_PERIPH)?
