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())

>>> f.minimum_address

>>> f.maximum_address

>>> len(f)

>>> f[f.minimum_address]

>>> f[f.minimum_address:f.minimum_address + 1]
bytearray(b'!')

See the test suite for additional examples.

Command line tool

Print general information about given binary format file(s).

$ bincopy info tests/files/in.hex
Data address ranges:
                         0x00000100 - 0x00000140

Convert file(s) from one format to another.

$ bincopy convert -i ihex -o srec tests/files/in.hex -
