Hi Cchechio,

using our Fox GM with the Fox Board, J6 and J7 headers are occupied with 
the GM board itself.
You have possibility to use some I/O through the P1 connector on the GM  
(look at the photo, it is named as "Audio in,out and general I/O".
See the schematic:
http://www.acmesystems.it/articles/00003/FOXGM_schematic.pdf

On P1 there are the following GPIO lines of port G:
IOG0    bidirectional
IOG24  bidirectional

IOG13
IOG14
IOG15  bidirectional but all three together with same direction

IOG16
IOG17
IOG18
IOG19  bidirectional but all four together with same direction

With these lines it is possible to interface several devices.

Moreover there are two pushbuttons user defined connected respectively 
to Ig2 and Ig4 that can be used as input lines.

Best regards,

Roberto Asquini
