Code will only return 0.0 for everything #65

Hi i am using your SerialBegin example and i can't seam to get the load cell to return any values. I am using an Intel Edison, stacked on a Sparkfun Base Block, then GPIO Block, this is wired over to a Sparkfun Load Cell Amp which is wired to a Sparkfun 200kg Load Cell. I have the right pins and i am able to compile the code and run it, but in the serial monitor it just displays 0.0 for every stage, there must be something i am doing wrong but i can't quite figure it out. Do you have any suggestions to why this is happening?

Thanks, Lewis.

sorry for the delay, did you fix the issue yet? are you sure your wiring is correct, especially the correct wiring of the clock and data pins?

In my experience, if you're getting 0.0 regardless of the input, then you've miswired it somehow. It took me several tries to get the wiring right, but once I did I got much more sensible outputs.

@LewisAstbury As others have suggested, try swapping your clk/dat lines and ensure they are connected to the right pins on your dev board.
