+ * Note that the SPARK Flex uses the following bounds for PWM values. These
+ * values should work reasonably well for most controllers, but if users
+ * experience issues such as asymmetric behavior around the deadband or
+ * inability to saturate the controller in either direction, calibration is
+ * recommended. The calibration procedure can be found in the SPARK Flex User
+ * Manual available from REV Robotics.
+ *
+ * \li 2.003ms = full "forward"
+ * \li 1.550ms = the "high end" of the deadband range
+ * \li 1.500ms = center of the deadband range (off)
+ * \li 1.460ms = the "low end" of the deadband range
+ * \li 0.999ms = full "reverse"
