That silly little tool really helped me understand synchronous serial communication, along with the different methods of sending the MSB. Can you hook up the scope and set the trigger for the first bit transition? Capture an image and post it on this thread. We can get this problem solved! Once we know the SX is generating something that makes sense, it'll only be a matter of getting the Prop to understand it too.
