USB HID Report Descriptor Parser in Python

1 Introduction

This is a similar tool as HID Descriptor Tool that is avaliable in USB-IF. Not intended to re-create the wheel, my purpose is to quickly create an utility that can parse the following USB HID Report Descriptors:

1. descriptors which are binaries
2. descriptors for an USB Sensor HUB

A script language (python) is chosen because of the need of writing it in a quick way.

Python Print String Descriptors for the USB HID Devices

1 Inctroduction

In this tutorial, we are going to write two small python programs that prints the String Descriptors for all the USB HID devices in the system. To do this, there are many choices of libraries for assistence. I will introduce two of them - PyUSB and PyWin32. PyUSB supports both Linux and Windows, and PyWin32 supports Windows only.

Writing Your First PyQt4 OpenGL Program

1 Introduction

In this tutorial, we are going to have a glimpse of OpenGL programming in Python. I will introduce several simple Qt GUI applications and show you basic OpenGL programs.
Python is a programming language that lets you work more quickly and integrate your systems more effectively. PyQt is a Python wrapper for the C++ GUI framework Qt. Qt is a framework that uses the native widgets to draw its user interfaces.
PyOpenGL is a cross-platform open source Python binding to the standard OpenGL API. OpenGL is an application program interface that is used to define 2D and 3D computer graphics.
The article is written under Debian Linux. Packages that are required will be installed using powerful APT tool. If you are not a Linux user, however, don't worry. Since Python is a cross-platform language, Qt is a cross-platform framework, OpenGL is also a cross-platform interface, all the programs in this article also work for you. Just 'translate' the package installations according to your system and have fun.
