Member Data Documentation

◆ BaudRate

uint32_t UART_InitTypeDef::BaudRate

This member configures the UART communication baud rate.

The baud rate register is computed using the following formula:

Note

For LPUART : Baud Rate Register = ((256 * lpuart_ker_ckpres) / ((huart->Init.BaudRate))) where lpuart_ker_ck_pres is the UART input clock divided by a prescaler.

For UART :

If oversampling is 16 or in LIN mode, Baud Rate Register = ((uart_ker_ckpres) / ((huart->Init.BaudRate)))
If oversampling is 8, Baud Rate Register[15:4] = ((2 * uart_ker_ckpres) / ((huart->Init.BaudRate)))[15:4] Baud Rate Register[3] = 0 Baud Rate Register[2:0] = (((2 * uart_ker_ckpres) / ((huart->Init.BaudRate)))[3:0]) >> 1 where uart_ker_ck_pres is the UART input clock divided by a prescaler

◆ ClockPrescaler

uint32_t UART_InitTypeDef::ClockPrescaler

Specifies the prescaler value used to divide the UART clock source.

This parameter can be a value of UART Clock Prescaler.

Definition at line 92 of file stm32h7xx_hal_uart.h.

◆ HwFlowCtl

uint32_t UART_InitTypeDef::HwFlowCtl

Specifies whether the hardware flow control mode is enabled or disabled.

This parameter can be a value of UART Hardware Flow Control.

Definition at line 80 of file stm32h7xx_hal_uart.h.

◆ Mode

uint32_t UART_InitTypeDef::Mode

Specifies whether the Receive or Transmit mode is enabled or disabled.

This parameter can be a value of UART Transfer Mode.

Definition at line 77 of file stm32h7xx_hal_uart.h.

◆ OneBitSampling

uint32_t UART_InitTypeDef::OneBitSampling

Specifies whether a single sample or three samples' majority vote is selected.

Selecting the single sample method increases the receiver tolerance to clock deviations. This parameter can be a value of UART One Bit Sampling Method.

Definition at line 88 of file stm32h7xx_hal_uart.h.

◆ OverSampling

uint32_t UART_InitTypeDef::OverSampling

Specifies whether the Over sampling 8 is enabled or disabled, to achieve higher speed (up to f_PCLK/8).

This parameter can be a value of UART Over Sampling.

Definition at line 84 of file stm32h7xx_hal_uart.h.

◆ Parity

uint32_t UART_InitTypeDef::Parity

Specifies the parity mode.

This parameter can be a value of UART Parity

Note: When parity is enabled, the computed parity is inserted at the MSB position of the transmitted data (9th bit when the word length is set to 9 data bits; 8th bit when the word length is set to 8 data bits).

Definition at line 70 of file stm32h7xx_hal_uart.h.

◆ StopBits

uint32_t UART_InitTypeDef::StopBits

Specifies the number of stop bits transmitted.

This parameter can be a value of UART Number of Stop Bits.

Definition at line 67 of file stm32h7xx_hal_uart.h.

◆ WordLength

uint32_t UART_InitTypeDef::WordLength

Specifies the number of data bits transmitted or received in a frame.

This parameter can be a value of UARTEx Word Length.
