无线数据包的内容：#define SENDVAL 5char SendPacket[]={0x0C,0x61,0x88,0x00,0x07,0x20,0xEF,0xBE,0x20,0x50,SENDVAL};请问以上数组中0x61和0x88是什么意思？

if(temp==0xde){ i=2; }else if(temp==0xbe){i=3; } ......}怎么理解“temp=temp | tem;//按位相或取结果判断定位键值”？另外，如果将P1改为用

（总线上只有一个DS18B20）tmpwritebyte(0xbe);//从暂存器中读取数据，第一字节为温度低8位，第二字节为温度高8位tmp_L8=tmpreadbyte();//读取温度低8位tmp_H8=tmpreadbyte();//读取温度高8位temp=tmp_H8;temp=temp
