Ok, I think we were getting confused about the MAX45434L data sheet 
addressing and thought the address of 0x50 corresponded to the chip. I 
now see that the address should be 0x28, however I know it's soldered 
properly and I still can't see it with i2cget...am I dead in the water 
or is there possibly another way to approach this?
