This section covers the porting of the NetMD Python code to C and integrating it into qhimdtransfer.

Python NetMD

• command line interface only
• requires Python (version dependency)
• requires some basic knowledge on setting up Python
• not intuitively usable
• code is in some parts highly experimental

The current Python NetMD implementation allows both downloads (all NetMD models) as well digital uploads (MZ-RH1/MZ-RH200 models only) as well as titling, listing and editing of tracks as well as remote controlling NetMD units. Analog capture for upload is supported for models other than MZ-RH1/MZ-RH200. Download code contains a valid but unencumbered root key to allow necessary encryption during transfers. The download code itself is highly experimental, however.

Porting of the Python code to C was already started. The resulting tarball can be downloaded here: libnetmd.

The current NetMD implementation in Python is divided into several scripts

Utilities:

• lsmd.py - list the contents of any NetMD
• upload.py - transfer tracks from NetMD to the computer (works with MZ-RH1 Walkman only)
• downloadhack.py - allows transfer of tracks from the computer to NetMD (using unencumbered keys)
• dump_md.py - allows analogue transfers of tracks from NetMD to the computer (any NetMD Walkman)
• lsusb.py - sample implementation of lsusb command using usb1.py
• mdctl.py - pdb-based command line to test libnetmd.py methods

Libraries:

• libnetmd.py - implementation of a NetMD library in Python (core module)
• libusb1.py - Ctypes-based python wrapper around libusb1
• usb1.py - object definitions for libusb1.py functions

• Finish already provided libnetmd
• Extend QHiMDTransfer to interface the new libnetmd
• Rename QHiMDTransfer to SyncMD (maybe)
