Member Data Documentation

BaudRate

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.

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 UART Word Length

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

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).

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

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

OverSampling

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
