这里取最后三条指令，做一下检查；

:04 02B0 00 92020008 AE

:04 0000 05 08000135 B9

:00 0000 01 FF

:04 02B0 00 92020008 AE

0x04 + 0x02 + 0xB0 + 0x92 + 0x02 + 0x08 = 0x152 ~0x52 + 1 = 0xAE

~按位取反

0x04 + 0x05 + 0x80 + 0x01 + 0x35 = 0X47 ~0x47 + 1 = 0XB9

~按位取反

:00 0000 01 FF

~0x01 + 1 = 0xFF

~按位取反

hex转bin文件

资深调包侠找到一个可以使用的包；

pip install intelhex

Per example, converting content of foo.hex to foo.bin addresses from 0 to FF:

$ python hex2bin.py -r 0000:00FF foo.hex

Or (equivalent):

$ python hex2bin.py -r 0000: -s 256 foo.hex
