    Lori, I need the 2-pole 2-zero controller for the CLA. It was included in the 2808 libraries but I could not find it adapted to run in the CLA. I have seen some 2-pole 2-zero code for the CLA in several Piccolo presentations, where they compare the code efficiency with the main CPU. Thank you for...
