为何以下程序没有按希望的那样点亮LED，是我的思路不对么USART.C
#include"UsartSet.h"
void USARTSet(void)
{
USART_InitTypeDef USART_InitStructure;
RCC_APB2PeriphClockCmd(RCC_APB2Periph_USART1,ENABLE);
USART_InitStructure.USART_BaudRate=115200;
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);
