Second updateMethod which is blocking

While using your nice lib for the SwitecX25 today I noticed, that I have to take care for a smooth movement myself.
Therefore I added a blocking update method. While I only use one motor at this arduino, this isn't a problem. And I have pretty long, blocking waiting time in my main loop, therefore the movement with your update method wasn't that nice.

Maybe you are interested in sharing these changes.
