应该是可以的吧,但是我配置好之后,程序编译没问题,点击debug后,Peripheral里却没有外设选项,这是因为什么呢?下图是我的Op
tion配置,以及调试出现问题的界面
程序:
#include "
STM32f10x.h"
#include <stdio.h>
void RCC_Configuration(void);
void GPIO_Configuration(void);
USART_InitTypeDef USART_InitStructure;
int main(void)
{
u16 F;
u8 data='A';
RCC_Configuration();
GPIO_Configuration();
USART_InitStructure.USART_BaudRate = 9600;
USART_InitStructure.USART_WordLength = USART_WordLength_8b;
USART_InitStructure.USART_StopBits = USART_StopBits_1;
USART_InitStructure.USART_Parity = USART_Parity_No;
USART_InitStructure.USART_HardwareFlowControl = USART_HardwareFlowControl_None;
USART_InitStructure.USART_Mode = USART_Mode_Rx | USART_Mode_Tx;
USART_Init(USART1, &USART_InitStructure);
USART_Cmd(USART1,ENABLE);
for(F=0;F<20;F++)
{
USART1->DR = data;
data++;
while((USART1->SR & (1<<6))==0) ;
}
}
void RCC_Configuration(void)
{
RCC_DeInit();
RCC_HSEConfig(RCC_HSE_ON);
while(RCC_GetFlagStatus(RCC_FLAG_HSERDY) == RESET);
RCC_HCLKConfig(RCC_SYSCLK_Div1); //HCLK = SYSCLK
RCC_PCLK2Config(RCC_HCLK_Div1); //PCLK2 = HCLK
RCC_PCLK1Config(RCC_HCLK_Div2); //PCLK1 = HCLK/2
RCC_PLLConfig(RCC_PLLSource_HSE_Div1,RCC_PLLMul_9); //PLLCLK = 8MHZ * 9 =72MHZ
RCC_PLLCmd(ENABLE); //Enable PLLCLK
while(RCC_GetFlagStatus(RCC_FLAG_PLLRDY) == RESET); //Wait till PLLCLK is ready
RCC_SYSCLKConfig(RCC_SYSCLKSource_PLLCLK); //Select PLL as system clock
while(RCC_GetSYSCLKSource()!=0x08); //Wait till PLL is used as system clock source
RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA,ENABLE);
RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOC,ENABLE);
RCC_APB2PeriphClockCmd(RCC_APB2Periph_AFIO,ENABLE);
RCC_APB2PeriphClockCmd(RCC_APB2Periph_USART1,ENABLE);
}
void GPIO_Configuration(void)
{
GPIO_InitTypeDef GPIO_InitStructure;
/* Configure USARTx_Tx as alternate function push-pull */
GPIO_InitStructure.GPIO_Pin = GPIO_Pin_9;
GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP;
GPIO_Init(GPIOA, &GPIO_InitStructure);
/* Configure USARTx_Rx as input floating */
GPIO_InitStructure.GPIO_Pin = GPIO_Pin_10;
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_IN_FLOATING;
GPIO_Init(GPIOA, &GPIO_InitStructure);
}

就是我不能打开Peripheral的外设操作窗口是吗?
