STM32串口配置注意事项是什么？

USART_InitStructure.USART_BaudRate = 9600;


USART_InitStructure.USART_WordLength = USART_WordLength_9b;  //此处在有奇偶校验时需要9个数据位，无奇偶校验时8个数据位


USART_InitStructure.USART_StopBits = USART_StopBits_1;


USART_InitStructure.USART_Parity = USART_Parity_Even;//偶校验


USART_InitStructure.USART_HardwareFlowControl = USART_HardwareFlowControl_None;


USART_InitStructure.USART_Mode = USART_Mode_Rx | USART_Mode_Tx;


USART_Init(USART1,&USART_InitStructure);
