Function Documentation

◆ HAL_DMA2D_ConfigLayer()

HAL_StatusTypeDef HAL_DMA2D_ConfigLayer	(	DMA2D_HandleTypeDef *	hdma2d,
		uint32_t	LayerIdx )

#include <stm32f4xx_hal_dma2d.h>

Configure the DMA2D Layer according to the specified parameters in the DMA2D_HandleTypeDef.

Parameters

hdma2d	Pointer to a DMA2D_HandleTypeDef structure that contains the configuration information for the DMA2D.
LayerIdx	DMA2D Layer index. This parameter can be one of the following values: DMA2D_BACKGROUND_LAYER(0) / DMA2D_FOREGROUND_LAYER(1)

Return values

◆ HAL_DMA2D_ConfigCLUT()

HAL_StatusTypeDef HAL_DMA2D_ConfigCLUT	(	DMA2D_HandleTypeDef *	hdma2d,
		DMA2D_CLUTCfgTypeDef	CLUTCfg,
		uint32_t	LayerIdx )

#include <stm32f4xx_hal_dma2d.h>

Configure the DMA2D CLUT Transfer.

Parameters

hdma2d	Pointer to a DMA2D_HandleTypeDef structure that contains the configuration information for the DMA2D.
CLUTCfg	Pointer to a DMA2D_CLUTCfgTypeDef structure that contains the configuration information for the color look up table.
LayerIdx	DMA2D Layer index. This parameter can be one of the following values: DMA2D_BACKGROUND_LAYER(0) / DMA2D_FOREGROUND_LAYER(1)

Note: API obsolete and maintained for compatibility with legacy. User is invited to resort to HAL_DMA2D_CLUTStartLoad() instead to benefit from code compactness, code size and improved heap usage.

◆ HAL_DMA2D_ProgramLineEvent()

HAL_StatusTypeDef HAL_DMA2D_ProgramLineEvent	(	DMA2D_HandleTypeDef *	hdma2d,
		uint32_t	Line )

#include <stm32f4xx_hal_dma2d.h>

Configure the line watermark.

Parameters

hdma2d	Pointer to a DMA2D_HandleTypeDef structure that contains the configuration information for the DMA2D.
Line	Line Watermark configuration (maximum 16-bit long value expected).

Note: HAL_DMA2D_ProgramLineEvent() API enables the transfer watermark interrupt.; The transfer watermark interrupt is disabled once it has occurred.
