  1. SDRAM Testing

    With a working serial interface it was time to try bringing up the external memory. I've maxed out the available external memory on this chip, it can support up to 64MB of SDRAM on each of the two banks and that's what I've got. To hit the full 64MB capacity …

  2. Motor Control

    We've already discussed what motors we're using. These motors need some fairly hefty speed control, they have a stall current of 3.4A. They've also got magnetic encoders which means we need real-time encoder monitoring ability. Real-time stuff on the Pi is challenging, and monitoring 4 quadrature encoders with one …
