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: Baud Rate Register[15:4] = ((2 * fclk_pres) / ((huart->Init.BaudRate)))[15:4] Baud Rate Register[3] = 0 Baud Rate Register[2:0] = (((2 * fclk_pres) / ((huart->Init.BaudRate)))[3:0]) >> 1 where fclk_pres is the USART input clock frequency

Note: Oversampling by 8 is systematically applied to achieve high baud rates.

◆ 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 79 of file stm32f7xx_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 76 of file stm32f7xx_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 73 of file stm32f7xx_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 70 of file stm32f7xx_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 63 of file stm32f7xx_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 60 of file stm32f7xx_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 USARTEx Word Length.
