/*********************************************************************
Function: uchar Remote_Transform(uchar mode,uchar *InBuffer)
功能: 将遥感数据转化成不同模式时的数据格式
输入：mode 表示当前遥感的工作模式，InBuffer 遥感数据存放地址
输出：OutBuffer 转化以后数据输出地址
返回：转换后数据长度
描述：上层调用此函数来将遥感数据按相应模式转化成相应的数据

mode 1:遥感  -\                       
mode 2:4方向   } 游戏手柄模式下的情况  
mode 3:8方向 -/	                      
	
mode 4:4按键
	
mode 5:鼠标
output_key的低四位表示四个按键位，1表示按下，0表示弹起；其中
0 bit表示up; 1 bit表示right; 2 bit表示down; 3 bit表示left;
