Functions

void DMA_ClearFlag (uint32_t DMA_FLAG)
 Clears the DMAy Channelx's pending flags.
void DMA_ClearITPendingBit (uint32_t DMA_IT)
 Clears the DMAy Channelx’s interrupt pending bits.
void DMA_Cmd (DMA_Channel_TypeDef *DMAy_Channelx, FunctionalState NewState)
 Enables or disables the specified DMAy Channelx.
void DMA_DeInit (DMA_Channel_TypeDef *DMAy_Channelx)
 Deinitializes the DMAy Channelx registers to their default reset values.
uint16_t DMA_GetCurrDataCounter (DMA_Channel_TypeDef *DMAy_Channelx)
 Returns the number of remaining data units in the current DMAy Channelx transfer.
FlagStatus DMA_GetFlagStatus (uint32_t DMA_FLAG)
 Checks whether the specified DMAy Channelx flag is set or not.
ITStatus DMA_GetITStatus (uint32_t DMA_IT)
 Checks whether the specified DMAy Channelx interrupt has occurred or not.
void DMA_Init (DMA_Channel_TypeDef *DMAy_Channelx, DMA_InitTypeDef *DMA_InitStruct)
 Initializes the DMAy Channelx according to the specified parameters in the DMA_InitStruct.
void DMA_ITConfig (DMA_Channel_TypeDef *DMAy_Channelx, uint32_t DMA_IT, FunctionalState NewState)
 Enables or disables the specified DMAy Channelx interrupts.
void DMA_SetCurrDataCounter (DMA_Channel_TypeDef *DMAy_Channelx, uint16_t DataNumber)
