012 * Playing with Fusion Venom Smart Motor with PWM control.
013 *
014 * <p>Note that the Venom 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.
018 *
019 * <ul>
020 *   <li>2.004ms = full "forward"
021 *   <li>1.520ms = the "high end" of the deadband range
022 *   <li>1.500ms = center of the deadband range (off)
023 *   <li>1.480ms = the "low end" of the deadband range
024 *   <li>0.997ms = full "reverse"
