zigbee（题型整理4）

题目：Zigbee节点板通电，程序开始运行时D5闪烁，2S后该LED变常亮，其余灯灭单击模块上的SW1（按下时间不超过1秒），D5、D6、D3、D4、依次闪烁1s后变常亮；长按“SW”，所有灯灭

本题难点是判断短按还是长按，所以我使用了一个计时器来判断。
核心代码是判断，返回temp

uint8 scankey(){  if(KEY1==0)  {    delay(100);    count1=0;    if(KEY1==0)    {      while(!KEY1){        temp=count1;        if(temp==100){          break;        }       }      return 1;     }  }  return 0;}
