(0011) 描 述：使用STK500_2 协议的bootloader，监控芯片 M16,数据通讯RS232
(0012) 已经非常精简的使用STK500_2 协议的MEGA16的bootloader.使用
(0013) ATMEL AVRStudio 4.xx STK500工具的进行软件升级。
(0014)
(0015) 本软件适合于个人学习，用于商业用途建议加加密措施
(0016)
(0017) 注意事项：在升级firmware后，进行verify，总是出错，这是正常现象
(0018) 因为升级的firmware文件不含bootloader程序，而verify时将读取整片
(0019) flash的内容，所以总是校验出错。如果你不放心，读取flash的内容和
(0020) 你烧写的firmware对比一下，看看哪里不一致就是了。
(0021)
(0022) 大家看看有没有什么写的不好的地方,请提出宝贵的意见！
