bincopy

About

Mangling of various file formats that conveys binary information (Motorola S-Record, Intel HEX, TI-TXT, Verilog VMEM, ELF and binary files).

Documentation: https://bincopy.readthedocs.io

Installation

.. code-block:: python

pip install bincopy

Example usage

Scripting

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

.. code-block:: pycon

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