串口要怎么设置我发的是0x55 循环发送 DSP收到的是乱码（0x6633循环）是起始位和停止位的配置问题？就高手解答！！！

void USART_Configuration(void)
{
USART_InitTypeDef USART_InitStructure;             //串口设置恢复默认参数
//初始化参数设置
USART_InitStructure.USART_BaudRate = 9600;                                  //波特率9600
USART_InitStructure.USART_WordLength = USART_WordLength_8b; //字长8位
USART_InitStructure.USART_StopBits = USART_StopBits_1;                //1位停止字节
USART_InitStructure.USART_Parity = USART_Parity_No;                   //无奇偶校验
USART_InitStructure.USART_HardwareFlowControl = USART_HardwareFlowControl_None;//无流控制
USART_InitStructure.USART_Mode = USART_Mode_Rx | USART_Mode_Tx;//打开Rx接收和Tx发送功能
USART_Init(USART2, &USART_InitStructure);                                        //初始化
USART_Cmd(USART2, ENABLE); //开启USART;
}
这是串口配置
