d-bug12 is both a Python api, and a command line interface for the Dbug-12 program flashed in Motorola's HC12 chips

d-bug12

Installation

pip install dbug12

You should have Python's user base directory in your path for the CLI to work properly. In case it's not, use python -m site --user-base to get it and add it to your system path.

Manually

Although the recommended way to install is using Python's package installer, there is an installation script (Linux only) in case you don't have pip set up.

sudo ./install
