In attach to this post you can download the pre-version of the software to control the shield. Finished testing just now and all seems working. The included documentation and usage notes will be completed soon but the essential for the sketch architecture understanding is included, hopefully.
Soon a new update, in the meantime feel free to comment and criticise.
The illustration below (decorative) is the hardware design architecture of the shield published for the first time in the preview document of the project.
Cheers.
