◆ LL_DMA2D_SetOutputColor()

__STATIC_INLINE void LL_DMA2D_SetOutputColor	(	DMA2D_TypeDef *	DMA2Dx,
		uint32_t	OutputColor
	)

Set DMA2D output color, expressed on 32 bits ([31:0] bits).

Note: Output color format depends on output color mode, ARGB8888, RGB888, RGB565, ARGB1555 or ARGB4444.; LL_DMA2D_ConfigOutputColor() API may be used instead if colors values formatting with respect to color mode is not done by the user code. OCOLR BLUE LL_DMA2D_SetOutputColor
OCOLR GREEN LL_DMA2D_SetOutputColor
OCOLR RED LL_DMA2D_SetOutputColor
OCOLR ALPHA LL_DMA2D_SetOutputColor

Parameters

DMA2Dx	DMA2D Instance
OutputColor	Value between Min_Data=0 and Max_Data=0xFFFFFFFF

Return values

None
