Function Documentation

void USART_DMACmd ( USART_TypeDef *  USARTx,
uint16_t  USART_DMAReq,
FunctionalState  NewState 

Enables or disables the USART's DMA interface.

USARTx,:where x can be 1, 2, 3, 4, 5 or 6 to select the USART or UART peripheral.
USART_DMAReq,:specifies the DMA request. This parameter can be any combination of the following values:
  • USART_DMAReq_Tx: USART DMA transmit request
  • USART_DMAReq_Rx: USART DMA receive request
NewState,:new state of the DMA Request sources. This parameter can be: ENABLE or DISABLE.
Return values
