012 * Digilent DMC 60 Motor Controller.
013 *
014 * <p>Note that the DMC uses the following bounds for PWM values. These values should work
015 * reasonably well for most controllers, but if users experience issues such as asymmetric behavior
016 * around the deadband or inability to saturate the controller in either direction, calibration is
017 * recommended. The calibration procedure can be found in the DMC 60 User Manual available from
018 * Digilent.
019 *
020 * <ul>
021 *   <li>2.004ms = full "forward"
022 *   <li>1.520ms = the "high end" of the deadband range
023 *   <li>1.500ms = center of the deadband range (off)
024 *   <li>1.480ms = the "low end" of the deadband range
025 *   <li>0.997ms = full "reverse"
