HAL_USART_Transmit_DMA() function
Simplex Send an amount of data in DMA mode.
Syntax
HAL_StatusTypeDef HAL_USART_Transmit_DMA(USART_HandleTypeDef *husart,
const uint8_t *pTxData,
uint16_t Size);
Implemented in ![]()
stm32f4xx_hal_usart.c:1243
Return value
HAL status
Notes
When USART parity is not enabled (PCE = 0), and Word Length is configured to 9 bits (M1-M0 = 01), the sent data is handled as a set of u16. In this case, Size must indicate the number of u16 provided through pTxData.
