Extio for Airspy HF+ now tested

As I received from Youssef an AirSpyHF+ engineering test unit, I managed to test the library published since past September. Really it works, as Youssef and a few volunteers promptly discovered before than me; however the library I used was a first release so it is missing of several features that in the meantime have been added.
As Youssef was so kind to send me another unit, even the multi device environment was developed and tested.
A new release that encompasses all the new features in airpsyhf lib is found clicking on the button below.

Extio for Airspy HF+

What is this software ?
It is an Extio shared library (DLL), a plugin that allows to use Airspy Hf+ radio with several SDR programs on Windows.

The Extio specification has been designed by Alberto's I2PHD ; I followed that specifications, so this module should work with Studio1, HDSDR and, hopefully, with all the extio compliant programs. Other than Studio1, I tested the module on HDSDR and with the original Alberto Di Bene I2PHD WinRad.

A shared library executable image, built using the MinGW environment, is found here. This image is just a proof of concept that I developed in order to verify the compatibility of my ExtIO framework with the new AirSPy HF+ host access library, compiled with GCC; libraries libusb-1.0 and libpthread are requested by the Airspy original code.
For my convenience I run MinGW on Windows, but it should be feasible to build it even on Unix. Moreover, probably other Windows compilers can be used.

In order to use the library, simply copy it in the same directory from where the SDR program executable is run. It shouldn't require any other additional dll.

The current executable has built-in some diagnostic code that produces a log file (named airspyhf-1.log) in the same directory where the dll is loaded from. In case you incurs in some anomaly, it is essential you provide me that file.
Make sure the user that runs the program has the write rights for that directory.

The source code will be found in the following GITHUB repository.

The code is licensed under the GPLv3 (with exception of libairspyhf code that retains its licence).

Please note that, using the git client on Windows, whilst is perfectly feasible both via CLI and GUI, is not mandatory, neither advisable, unless you want to contribute to develop the code.

So, if you want the source just in order to take a look or just for rebuild on your system, it is preferrable use the Download button present in the GitHUB repository home page previously mentioned.

Please signal any bug and feature request using the GitHub Issues page.
Do not use mailing lists, forums, Fuckbook or other, so called, social media, because I don't read them frequently (if ever).
