Member Data Documentation

◆ BaudRate

uint32_t USART_InitTypeDef::BaudRate

This member configures the Usart communication baud rate. The baud rate is computed using the following formula:

IntegerDivider = ((PCLKx) / (8 * (husart->Init.BaudRate)))
FractionalDivider = ((IntegerDivider - ((uint32_t) IntegerDivider)) * 8) + 0.5

Definition at line 48 of file stm32f4xx_hal_usart.h.

◆ CLKLastBit

uint32_t USART_InitTypeDef::CLKLastBit

Specifies whether the clock pulse corresponding to the last transmitted data bit (MSB) has to be output on the SCLK pin in synchronous mode. This parameter can be a value of USART Last Bit

Definition at line 75 of file stm32f4xx_hal_usart.h.

◆ CLKPhase

uint32_t USART_InitTypeDef::CLKPhase

Specifies the clock transition on which the bit capture is made. This parameter can be a value of USART Clock Phase

Definition at line 72 of file stm32f4xx_hal_usart.h.

◆ CLKPolarity

uint32_t USART_InitTypeDef::CLKPolarity

Specifies the steady state of the serial clock. This parameter can be a value of USART Clock Polarity

Definition at line 69 of file stm32f4xx_hal_usart.h.

◆ Mode

uint32_t USART_InitTypeDef::Mode

Specifies whether the Receive or Transmit mode is enabled or disabled. This parameter can be a value of USART Mode

Definition at line 66 of file stm32f4xx_hal_usart.h.

◆ Parity

uint32_t USART_InitTypeDef::Parity

Specifies the parity mode. This parameter can be a value of USART 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 59 of file stm32f4xx_hal_usart.h.

◆ StopBits

uint32_t USART_InitTypeDef::StopBits

Specifies the number of stop bits transmitted. This parameter can be a value of USART Number of Stop Bits

Definition at line 56 of file stm32f4xx_hal_usart.h.

◆ WordLength

uint32_t USART_InitTypeDef::WordLength

Specifies the number of data bits transmitted or received in a frame. This parameter can be a value of USART Word Length
