That's not a stupid question because I think more people make this mistake.
In the attachment I numbered the pins how I think they should be.

As mentioned above I tried both address but they both don't work. After that I did connect the chip to a motor port to see if any of the led wen't on or off but that didn't make a different. It might be possible that I damaged the chip by doing that.
