Description
uint32_t
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.
uint32_t
Specifies the number of data bits transmitted or received in a frame. This parameter can be a value of USART_Word_Length.
uint32_t
Specifies the number of stop bits transmitted. This parameter can be a value of USART_Stop_Bits.
uint32_t
Specifies the parity mode. This parameter can be a value of USART_Parity.
uint32_t
Specifies whether the Receive or Transmit mode is enabled or disabled. This parameter can be a value of USART_Mode.
uint32_t
Specifies the steady state of the serial clock. This parameter can be a value of USART_Clock_Polarity.
uint32_t
Specifies the clock transition on which the bit capture is made. This parameter can be a value of USART_Clock_Phase.
uint32_t
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.
