pip install bincopy

Example usage

Scripting

A basic example converting from Intel HEX to Intel HEX, SREC, binary, array and hexdump formats:

>>> import bincopy
>>> f = bincopy.BinFile("tests/files/in.hex")
>>> print(f.as_ihex())

The fill subcommand

Fill empty space between segments. Use --max-words to only fill gaps smaller than given size.

$ bincopy info tests/files/in_exclude_2_4.s19 | grep byte
    0x00000000 - 0x00000002 (2 bytes)
    0x00000004 - 0x00000046 (66 bytes)
$ bincopy fill tests/files/in_exclude_2_4.s19 filled.s19
$ bincopy info filled.s19 | grep byte
    0x00000000 - 0x00000046 (70 bytes)
