uint32_t UART_InitTypeDef::BaudRate

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

• IntegerDivider = ((PCLKx) / (8 * (OVR8+1) * (huart->Init.BaudRate)))
• FractionalDivider = ((IntegerDivider - ((uint32_t) IntegerDivider)) * 8 * (OVR8+1)) + 0.5 Where OVR8 is the "oversampling by 8 mode" configuration bit in the CR1 register.

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

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

uint32_t UART_InitTypeDef::OverSampling

Specifies whether the Over sampling 8 is enabled or disabled, to achieve higher speed (up to fPCLK/8). This parameter can be a value of UART Over Sampling

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).
