(0004) 	                  作者：詹卫前		
(0005) 	使用注意：1、应包含头文件slavr.h
(0006)               2、在工程选项中的Additional Lib中填入slavr
(0007) 		         使用编译器使用附加库文件libslavr.a
(0008) 			  3、使用SL-AVRAD实验设备
(0009)     接线说明：1、PA.0(PIN40)处接电平指示LED的短路块跳开
(0010) 			  2、A/D和VX之间的短路块闭合
(0011) 			  3、AREF(PIN32)和AVCC(PIN30)接VCC
(0012) 			  4、AGND(PIN31)接GND
