; 
;SLAVR综合程序
;1.LED及LCD显示程序,有自动识别LED或LCD功能
;2.键盘扫描输入程序,0-F为16个数字键,还有上档功能键,EXEC-执行键,E2PROM-读键
;SRAM-读写键,MON-返回初始状态键,LAST-上一单无地址键,NEXT-下一单无地址键
;SHIFT-转换上档功能键,先按SHIFT键,再按标名的上档键,就执上档键的命令功能
;/RST-复位键,执行程序后,要机器回到初始化状态,必须按复位键
;按数字键显示对应数字,并有小数点作为光标,提示下一步工作位置,按命令键执行相应命令
;0070H-01FFH读、写内部SRAM(监控规定SRAM读写范围)
;0000H-01FFH读写片内E2PROM数据
;0200H-歌曲-祝你生日快乐,万水千山总是情
;0300H-LED上8字循环显示
;0320H-LED上0-F字符循环显示
;0400H-逐次逼近法A/D转换(需接网络电阻,另见说明)
;0500H-LCD初始化程序
;0700H-LCD上尖头字符左右移位程序
;0740H-LCD上0-F字符循环显示
;0800H-LCD显示LCD所有字符
