For the AS5145B, on page 29 it says that the default firmware has the incremental mode set up for use.

Ok. Well that's just a little weird. Who names their pins Test* and then uses them in normal operation? Bizarre.

So it looks like sg999 has it right. Take a look at the WPI instructions. The only gotcha is that the CSn pin needs to be pulled low to use this feature. Then it works just like a standard encoder.

On a side note, it looks like this chip can take rotational speeds up to about 15,000 RPM. It looks like to go this fast would require putting the chip in high speed mode, but it really is unclear.

Good find!
