  1. I love the functionality of the Discovery two. It does everything I need except an high performance A-B quadrature encoder state counter like what is used to count A-B outputs of optical encoders. I saw the post where you implemented a quadrature decoder and counter with scripts/code. I need the same functionality but with much greater performance (A-B edge separation of less than 40 nanoseconds). Since there is a FPGA in the Discovery 2 board is it possible to add this same function to the FPGA code to achieve greater performance? Thank you
