哪位朋友由STM32F030R8T6的模板用的一个模板串口死活出不来反复查看配置也没问题想换个模板试一下谢谢各位

这是我写的程序

#include "stm32f0xx.h"
#include "delay.h"

void MY_USART_Init(void)
{
GPIO_InitTypeDef GPIO_InitStructure;
USART_InitTypeDef USART_InitStructure;
NVIC_InitTypeDef NVIC_InitStructure;

RCC_APB2PeriphClockCmd(RCC_APB2Periph_USART1,ENABLE);
RCC_AHBPeriphClockCmd(RCC_AHBPeriph_GPIOB,ENABLE);

GPIO_InitStructure.GPIO_Mode=GPIO_Mode_AF;
GPIO_InitStructure.GPIO_OType=GPIO_OType_PP;
GPIO_InitStructure.GPIO_Pin=GPIO_Pin_6;
GPIO_InitStructure.GPIO_Speed=GPIO_Speed_Level_2;
GPIO_Init(GPIOB,&GPIO_InitStructure);

GPIO_InitStructure.GPIO_Mode=GPIO_Mode_IN;
GPIO_InitStructure.GPIO_Pin=GPIO_Pin_7;
GPIO_InitStructure.GPIO_PuPd=GPIO_PuPd_NOPULL;
GPIO_InitStructure.GPIO_Speed=GPIO_Speed_Level_2;
GPIO_Init(GPIOB,&GPIO_InitStructure);

USART_InitStructure.USART_BaudRate=9600;
USART_InitStructure.USART_HardwareFlowControl=USART_HardwareFlowControl_None;
USART_InitStructure.USART_Mode=USART_Mode_Rx|USART_Mode_Tx;
USART_InitStructure.USART_Parity=USART_Parity_No;
USART_InitStructure.USART_StopBits=USART_StopBits_1;
USART_InitStructure.USART_WordLength=USART_WordLength_8b;
USART_Init(USART1,&USART_InitStructure);

  USART_Cmd(USART1,ENABLE);//使能串口1

USART_ITConfig(USART1,USART_IT_RXNE,ENABLE);//开启接收中断

NVIC_InitStructure.NVIC_IRQChannel=USART1_IRQn;
NVIC_InitStructure.NVIC_IRQChannelCmd=ENABLE;
NVIC_InitStructure.NVIC_IRQChannelPriority=1;
NVIC_Init(&NVIC_InitStructure);

}

void USART1_IRQHandler(void)
{
u8 res;
   if(USART_GetITStatus(USART1,USART_IT_RXNE))
{
   res= USART_ReceiveData(USART1);
   USART_SendData(USART1,res);
  }
}

int main(void)
{

delay_init();///定时器初始化
  MY_USART_Init();
while(1);

}
