I am thinking of using a Stellaris Launchpad (LM4F120XL) as a robot controller. If I had something like this (http://www.pololu.com/catalog/product/1551) how would I go about interfacing with the quadrature encoders? This TI webpage says "Advanced motion control capability, with up to 16 PWM outputs and two quadrature encoder interfaces" but I cannot find the terms "quadrature encoder" or "QEI" in the Launchpad manual. Am I going to need to learn the gritty details of quadrature encoding and write my own C interface? I am very new to all this, so a gentle shove in the right direction would be awesome.
