Intel Hex文件如下。倒数第二行的最后一个数据字节“1826”，是这个文件的CRC16校验码。
更改了文件中的某个数据字之后，在这一行最后的校验和，已经有专门的小程序可以计算出来更改。
但是，倒数第二行的1826，用网上的CRC在线计算工具，怎么也算不出来。
试过选择全部，或只选择数据区，或不要第一行（因为这块电子板的不同版本的文件，开头第一行都一样）；试过各种CRC16的算法。。。
确认“1826”是CRC16，因为有原厂家的文件说明。
哪位大侠可以提供帮助，大谢！

另外再提供另一个HEX文件，这个是在中间位置（第151行）有个CRC校验码“BE00”，是不是也应该是一样的算法（同一台设备里的不同电子板里的EPROM）？
这个文件太长（共4097行），校验码之后的全部都是FFFFFFF，所以后面的就没有复制过来。
