U盘文件读写示例程序

说明：  modbus通信规约的汇编程序，可供通信编程时参考使用(Modbus communication protocol compilation procedures, communications programming for the use of reference)

通过无线模块接收GPS压缩数据，并进行校验和错误恢复，恢复算法采用位判别，三中取二。(GPS compressed data received through the wireless module and the checksum error recovery, the recovery algorithm uses a bit discriminant of three samples.)

最近几天突然对红外线遥控器发生兴趣，于是上网混了一下，发现编码方式有好几种，而且同一种编码方式又有许多不同的细节，为了弄清楚手头的遥控器是出身何门，无奈手头又没有logic分析器之类可望不可及（广东话里“及”同“望”都系“睇”既意思）的东西，遂萌生了写这个软件的冲动。(Infrared logic analyzer )

RC4算法的Asm实现，实现效率高，可以很方便的用到工程中去(Asm achieve RC4 algorithm to achieve high efficiency, can be very easy to use project to)

用PIC16f1847做的流水灯，经过测试可以运行(travelling LED program)
