STM32 串口通信使用奇偶校驗

• STM32串口通信如果使用奇偶校驗，需要設置數據位長度為9bit

	
USART_InitStructure.USART_BaudRate = 9600;             
USART_InitStructure.USART_WordLength = USART_WordLength_9b;
USART_InitStructure.USART_StopBits = USART_StopBits_1;
USART_InitStructure.USART_Parity = USART_Parity_Odd;
USART_InitStructure.USART_HardwareFlowControl = USART_HardwareFlowControl_None;
USART_InitStructure.USART_Mode = USART_Mode_Rx | USART_Mode_Tx;
USART_Init( USART3, &USART_InitStructure);
