uint32_t USART_InitTypeDef::USART_BaudRate

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

IntegerDivider = ((PCLKx) / (8 * (OVR8+1) * (USART_InitStruct->USART_BaudRate)))
FractionalDivider = ((IntegerDivider - ((u32) IntegerDivider)) * 8 * (OVR8+1)) + 0.5 Where OVR8 is the "oversampling by 8 mode" configuration bit in the CR1 register.

uint16_t USART_InitTypeDef::USART_WordLength

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

Definition at line 56 of file stm32f4xx_usart.h.

uint16_t USART_InitTypeDef::USART_StopBits

Specifies the number of stop bits transmitted. This parameter can be a value of USART_Stop_Bits

Definition at line 59 of file stm32f4xx_usart.h.

uint16_t USART_InitTypeDef::USART_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).

uint16_t USART_InitTypeDef::USART_Mode

Specifies wether the Receive or Transmit mode is enabled or disabled. This parameter can be a value of USART_Mode

Definition at line 69 of file stm32f4xx_usart.h.

uint16_t USART_InitTypeDef::USART_HardwareFlowControl

Specifies wether the hardware flow control mode is enabled or disabled. This parameter can be a value of USART_Hardware_Flow_Control
