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

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

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

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).

Mode

uint32_t USART_InitTypeDef::Mode

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
