用的STM8S208（UM0482）的开发板学习的时候用的风驰的STM8的教程在学 但是学到中断的时候发现按风驰的例子我修改对应的IO来调的时候不行像教程那样。查了很久没有办法，只能发帖请各位老师帮帮忙，下面是程序 。key_exti.h
#include "key_exti.h"
void Buttom_Init(void)
{
GPIO_Init(GPIOC,Buttom0|Buttom1|Buttom2,GPIO_MODE_IN_PU_IT);
EXTI_SetExtIntSensitivity(EXTI_PORT_GPIOC, EXTI_SENSITIVITY_FALL_ONLY);
}

#include "stm8s.h"
#define Buttom0 GPIO_PIN_0
#define Buttom1 GPIO_PIN_1

void Buttom_Init(void);
#endif
led.c
#include "led.h"
void LED_Init(void)
{
GPIO_Init(GPIOH,(led1|led2|led3|led4),\
GPIO_MODE_OUT_PP_HIGH_FAST);//定义LED的管脚的模式
}
void SetLedOFF(void)
{
GPIO_Write(GPIOH, 0xff);
}
void Led_Reverse(GPIO_Pin_TypeDef LedPins)
{
GPIO_WriteReverse(GPIOH, LedPins);
}
led.h

while (1)

}
void Delay(u32 nCount)
