LL_DMA2D_Init() function
Initialize DMA2D registers according to the specified parameters in DMA2D_InitStruct.
Syntax
Implemented in ![]()
stm32f4xx_ll_dma2d.c:159
Return value
An ErrorStatus enumeration value: - SUCCESS: DMA2D registers are initialized according to DMA2D_InitStruct content - ERROR: Issue occurred during DMA2D registers initialization
Notes
DMA2D transfers must be disabled to set initialization bits in configuration registers, otherwise ERROR result is returned.
