HAL_UART_Transmit() function

Sends an amount of data in blocking mode.

Syntax

from stm32f4xx_hal_uart.h:745

HAL_StatusTypeDef HAL_UART_Transmit(UART_HandleTypeDef *huart, const uint8_t *pData, uint16_t Size, uint32_t Timeout);

Implemented in stm32f4xx_hal_uart.c:1135

Arguments

huart

Pointer to a UART_HandleTypeDef structure that contains the configuration information for the specified UART module.

pData

Pointer to data buffer (u8 or u16 data elements).

Size

Amount of data elements (u8 or u16) to be sent

Timeout

Timeout duration

Return value

HAL status

Notes

When UART 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 pData.
