[求助] 初学STM32的串口实验，在接收时出现以下的乱码？是什么原因呢

这是我接收到得乱码截图，请各位大侠指教下是什么原因呢？谢谢了啊

附上程序：

#include "stm32f10x.h"
GPIO_InitTypeDef GPIO_InitStructure; 

USART_InitTypeDef USART_InitStructure; 

unsigned char TxBuf1[100] = "神州三号，串口测试程序";
unsigned char i;

void gpio_init()   

{
    RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA,ENABLE);  
    GPIO_StructInit(&GPIO_InitStructure);
    GPIO_InitStructure.GPIO_Pin = GPIO_Pin_9;
    GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP;
    GPIO_Init(GPIOA , &GPIO_InitStructure);
    GPIO_InitStructure.GPIO_Pin = GPIO_Pin_10;
    GPIO_InitStructure.GPIO_Mode = GPIO_Mode_IN_FLOATING;
    GPIO_Init(GPIOA, &GPIO_InitStructure); 
}
void usart_init()   

{
    RCC_APB2PeriphClockCmd(RCC_APB2Periph_USART1,ENABLE);
 USART_StructInit(&USART_InitStructure);
    USART_InitStructure.USART_BaudRate = 115200;    //设置波特率为115200//
    USART_InitStructure.USART_WordLength = USART_WordLength_8b;   //设置数据位为8位//
    USART_InitStructure.USART_StopBits = USART_StopBits_1;     //设置停止位为1位//
    USART_InitStructure.USART_Parity = USART_Parity_No;      //无奇偶校验位//
    USART_InitStructure.USART_Mode = USART_Mode_Rx | USART_Mode_Tx;    //发送与接收//
    USART_InitStructure.USART_HardwareFlowControl =USART_HardwareFlowControl_None;   //没有硬件流控//
 USART_Init(USART1, &USART_InitStructure);  //对串口1进行初始化
 USART_ITConfig(USART1, USART_IT_RXNE, ENABLE);  //接收的中断使能打开：
    USART_ITConfig(USART1, USART_IT_TXE, ENABLE);  //发送的中断使能打开
 USART_Cmd(USART1 , ENABLE);

}

int main()   
{ 
   usart_init();
   gpio_init();
  for( i = 0; TxBuf1 != '\0'; i++) {
USART_SendData(USART1 , TxBuf1);
while(USART_GetFlagStatus(USART1, USART_FLAG_TC)==RESET);
}
 
}
