}
void EXTI15_10_IRQHandler(void)
{
delay_ms(10); //消抖
if(!GPIO_ReadInputDataBit(GPIOB,KEY1)){ //读按键接口的电平
GPIO_WriteBit(GPIOB,LED1,(BitAction)(1-GPIO_ReadOutputDataBit(GPIOB,LED1))); //LED取反
LED0=!LED0;
}
OneNet_SendData(); //发送数据
EXTI_ClearITPendingBit(EXTI_Line11); //清除EXTI0线路挂起位
}
还有一个问题。OneNet_SendData();不能更新数据。
