I'm not sure why you are getting an exception in the Shieldbase dll, but you need to specify a pin for the Chip Select.

If you're using a device connected to GoSocket 3 you would use (Cpu.Pin)4 as can be seen in the above schematic. 

Also, I and others have run into SPI bugs when running under ~3000 kHz. So you may want to up your speed. 

Thank you yogotie.

ST updated their website - all the links fro STDFU Test links are broken and I couldn't find good ones. 

It is a little ambitious, but you can create GoBus modules using other microprocessors as "modules". In doing this, you gain all the GPIO pins of the new microprocessor. 

I have done this with a Parallax Propeller and am also doing it with a Netduino Plus 2. Unfortunately, the code isn't public yet (it will be by April). If you are not interested in the wait and want to start writing your own drivers, don't be afraid to PM me for help. 

Also, keep in mind that every GoBus is essentially a SPI bus - if you find a SPI I/O expander you could talk directly to it over the GoBus - granted, you will have to write a custom driver and will lose the benefits of GoBus 1.5/2.0. 

Good luck!

Paul you were absolutely correct, I changed the values to > 0x20 and now it's working, thanks a lot.  

Chris - not that it matters but it's the Adafruit FTDI Cable
