mini板按键实验，遇到时钟问题。

起名巨烦

#include "sys.h"
#include "usart.h"
#include "delay.h"
#include "led.h"
#include "key.h"
#include "stm32f10x.h"

int main(void)

    LED1=!LED1;
break;
case WKUP_PRES:
    LED0=!LED0;
LED1=!LED1;
break;
default:
      delay_ms(20);

}

}



}


compiling main.c...

        Stm32_Clock_Init(9);

程序是原子哥的程序。可是编译时出现了时钟的问题。




#include "key.h"
#include "delay.h"


void KEY_Init(void)
{
    RCC->APB2ENR|=1<<2;
    RCC->APB2ENR|=1<<4;

JTAG_Set(SWD_ENABLE);  

GPIOA->CRL&=0xFFFFFFF0;
GPIOA->CRL|=0x00000008;

GPIOA->CRH&=0x0FFFFFFF;
GPIOA->CRH|=0x80000000;
GPIOA->ODR|=1<<15;

GPIOC->CRL&=0xFF0FFFFF;
GPIOC->CRL|=0x00800000;
GPIOC->ODR|=1<<5;

}

u8 KEY_Scan(u8 mode)
{
static u8 key_up=1;
if(mode)key_up=1;  
if(key_up&&(KEY0==0||KEY1==0||WK_UP==1))
{
delay_ms(10);
key_up=0;
if(KEY0==0)return KEY0_PRES;
else if(KEY1==0)return KEY1_PRES;
else if(WK_UP==1)return WKUP_PRES;
}else if(KEY0==1&&KEY1==1&&WK_UP==0)key_up=1; 
return 0;
}

这个事按键的问题。帮帮小弟~~

lycreturn

你的sys.h 是不是有问题哦    你点开看看, 是不是这些函数和宏都没有定义
