Notes and commentaries for software developers

Fundamentals

This app interfaces hardware devices through HID feature reports. The binary format of those reports is called "data version", which is reported by the device itself. See HID notes for a complete description.

The source code includes a "module" which can be reused for custom applications. Implements all the details to enumerate and interface supported devices.

Source code

In fact, there are two different implementations for this app, as described bellow.

Python implementation

Currently active and maintained.

It was tested successfully with Python 3.12, however, PyInstaller does not work with that version. Use Python 3.11.7 for freezing.

Direct release dependencies are:

• hidapi
• NiceGUI
• appstrings

There is a "requirements.txt" file for all dependencies.

Development dependencies includes PyInstaller.

At the time of writing, it was not possible to freeze using "zipapp" with success.

Delphi implementation

Can be found in the "delphi-implementation" branch of this project. Currently not active nor maintained. However, this situation could be reverted in the future. This implementation works with data version 1.1, but not with previous ones.

Future work

The decision to continue development with one technology or another depends on the drawbacks of those technologies and may change in the future.
