Romeo all in one + PLL + encoder

Development Boards Arduino

Hi,

my question is not about a product bought from sparkfun. But I as I fail to get help from the manufacturers forum, I hope to find some help here.

It is about using PLL + encoder on the Romeo all in one board.

As far as I understood it:

the encoder should directly be hooked up to the PLL control.

With PWM I need to do the control via the code. But with PLL the electronics should do it by using the encoder as speed feedback signal.

How do I set this up?

Thanks
