USART Init Structure definition.
uint32_t USART_InitTypeDef::BaudRate |
This member configures the Usart communication baud rate. The baud rate is computed using the following formula: Baud Rate Register[15:4] = ((2 * fclk_pres) / ((huart->Init.BaudRate)))[15:4] Baud Rate Register[3] = 0 Baud Rate Register[2:0] = (((2 * fclk_pres) / ((huart->Init.BaudRate)))[3:0]) >> 1 where fclk_pres is the USART input clock frequency (fclk) divided by a prescaler.
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.
uint32_t USART_InitTypeDef::CLKPhase |
Specifies the clock transition on which the bit capture is made. This parameter can be a value of USART Clock Phase.
uint32_t USART_InitTypeDef::CLKPolarity |
Specifies the steady state of the serial clock. This parameter can be a value of USART Clock Polarity.
uint32_t USART_InitTypeDef::ClockPrescaler |
Specifies the prescaler value used to divide the USART clock source. This parameter can be a value of USART Clock Prescaler.
uint32_t USART_InitTypeDef::Mode |
Specifies whether the Receive or Transmit mode is enabled or disabled. This parameter can be a value of USART Mode.
uint32_t USART_InitTypeDef::Parity |
Specifies the parity mode. This parameter can be a value of USART Parity
uint32_t USART_InitTypeDef::StopBits |
Specifies the number of stop bits transmitted. This parameter can be a value of USART Number of Stop Bits.
uint32_t USART_InitTypeDef::WordLength |
Specifies the number of data bits transmitted or received in a frame. This parameter can be a value of USARTEx Word Length.
