Once you’ve received our board kits, you’ll need to assemble them, install our software libraries on your Pi. Then you can test your assembled boards to make sure that everything is working.
Raspberry Pi Interface Board
I2C Port Extender
Software
The guide for the Quick2Wire Python API is on github.
I have received my boards and assembled them. Everything went fine until the push button test to check the status of GPIO 17, no matter what I do it’s always “1″ (high) even if I jumper it to gnd on the interface board header. I even removed the push button in the event it may have been bad.
When I test the GPIO 17 on the Raspberry Pi without the interface board attached, I am able to read it as a “1″ or “0″ so the problem must be in the interface board. What might be causing this problem? The led test went fine and I am getting other pins to read fine thru the header.
any help would be appreciated.
Thanks,
Dewy
Thanks for getting in touch. Would you mind posting this question to the discussion group?

Is there a testing guide similar to the one for the interface board for the I2C port extender? I’ve now finished putting it together and now want to get testing and using it. The testing guide was excellent to get me started on the first board, the interface board, but I’m a bit stuck on where to start with the port expander. I bought it as I need more GPIO ports for my projects. I’ve read the various stuff on I2C but don’t know how it relates specifically to the port expander. Thanks!
