/************************************************************
*GetKey
读键盘数据
建议10ms调用一次此函数，不同调用时间需要修改函数内的相关参数以达到比较好的效果
参数：
	g_ucKeyMode=1时,单次模式
	g_ucKeyMode=0时,持续模式

返回值：
   0--按键无变化
   1 --按键有按下：
   	单次模式下，当按键第一次按下才返回一次该值；
		持续模式下，按着按键不放将间隔返回该值
		g_ulKeyValue保存当前按键值
   -1 --按键有释放.不管单次模式还是持续模式，当按键释放时只返回一次
		释放后，g_ulKeyValue保存上次按下的按键值
