As well as being the UK direct sales rep for SUB-20 modules, I'm a LabVIEW developer.
I'm sharing these drivers as a work-in-progress. I'd welcome any comments or suggestions.
They currently support all SUB-20 functions (I think) except:
MDIO, Bit-bang I2C, RS232/RS485, FIFO / Slave modes
I hope to add the rest in the next few weeks.
There are several examples included that should allow you to be up and running in a matter of moments.
Please note you will have to install the appropriate software package from XDIMAX first: http://www.xdimax.com/sub20/sub20.html#DLD
The drivers were developped in LabVIEW 2011, but I've down-saved them to 8.5 so people with older versions can use them.

Looking forward to your comments...

PS. We stock most SUB-20 modules and can deliver next-day to UK. Airmail to most European countries.
