stm32f103RB的串口设置如下：
USART_InitStructure.USART_BaudRate = 19200;
  USART_InitStructure.USART_WordLength = USART_WordLength_9b;
  USART_InitStructure.USART_StopBits = USART_StopBits_1;
  USART_InitStructure.USART_Parity = USART_Parity_Even;
  USART_InitStructure.USART_Mode = USART_Mode_Rx | USART_Mode_Tx;
  USART_InitStructure.USART_HardwareFlowControl = USART_HardwareFlowControl_None;
  USART_Init(USART1, &USART_InitStructure);

  USART_ClockInitStruct.USART_Clock = USART_Clock_Disable;
  USART_ClockInitStruct.USART_CPOL = USART_CPOL_Low;
  USART_ClockInitStruct.USART_CPHA = USART_CPHA_2Edge;
  USART_ClockInitStruct.USART_LastBit = USART_LastBit_Disable;
  USART_ClockInit(USART1,&USART_ClockInitStruct);

  USART_ITConfig(USART1, USART_IT_RXNE, ENABLE);
  USART_Cmd(USART1, ENABLE);

PC端的串口调试助手设置如下：
19200,8,1,Even,nonefile:///d:/1.jpg

但是实际测试了一下就有问题了，stm32发到pc机的数据是正确的，但是从pc机发到stm32的数据就不对了，请各位高手分析一下，谢了!
