Python script to calculate LPC firmware checksums

Project description

# lpc_checksum
Python script to calculate LPC firmware checksums, based on the C version by Roel Verdult. It can be used as a standalone application, or as a Python module that integrates directly in a build environment (e.g. SCons). It does not need to be compiled.

[![Build Status](https://travis-ci.org/basilfx/lpc_checksum.svg?branch=master)](https://travis-ci.org/basilfx/lpc_checksum)

## Requirements
The only requirement is Python 2.7 or Python 3.5+.

## Installation
This module can be installed from Pypi via `pip install lpc_checksum`. Alternatively, you can install the latest version by cloning this repository and run `python setup.py install`.

## Usage
There are two ways of using `lpc_checksum`.

### Standalone
When installed via Pip or from source, the command `lpc_checksum` should be available on your PATH. By default, it assumes the input file is a binary file.

`lpc_checksum <firmware.bin|hex> [--format=bin] [--readonly]`

Program exits with a non-zero error code when it failed.

### As a module
```
import lpc_checksum

checksum = lpc_checksum.checksum(input_file, [readonly=True])
```

On error, an exception will be raised.

## License
See the `LICENSE` file (MIT license).
