To reset measurements for the yaw gyro ahrs.reset().
These encoders function the same as external encoders, but are connected to the talon's encoder port and thus can be directly accessed from the talon object. To see if the encoder is stopped turning boolean stopped = sampleEncoder.getStopped().To get current direction boolean direction = sampleEncoder.getDirection().To get speed double rate = sampleEncoder.getRate().To get period between clicks double period = sampleEncoder.getPeriod().To get distance double distance = sampleEncoder.getDistance().To get count of clicks int count = sampleEncoder.get().How many samples to take (1-127) when determining the period tSamplesToAverage(7).Reverse the direction encoder counts tReverseDirection(true).How much distance is traveled every encoder pulse tDistancePerPulse(5).Minimum rate (rotation/time) before device is stopped tMinRate(10).To set max period (secs) without clicks before it is considered at rest tMaxPeriod(.1).To initialize Encoder sampleEncoder = new Encoder(0, 1, false, 4X).This is done through counting the number of "clicks", which increments or decrements with every slight rotation. To get magnitude Math.sqrt(xAxis*xAxis + yAxis*yAxis) Įncoders are used for measuring rotation.To get angle in degrees Math.atan2(xAxis, -yAxis) * 180 / Math.PI.To get angle in radians Math.atan2(xAxis, -yAxis).To get button values Joy.getRawButton(0) with boolean output.To get axis values Joy.getRawAxis(0) with value between -1 and 1.To initialize Joystick Joy = new Joystick(0).Joystick objects can receive joystick and button input. Joysticks are (misleadingly) an umbrella term for all user input devices, including gamepads, joysticks, etc. SET position CANSparkMax.getEncoder().setPosition() //used for aeroid out the encoders, and resetting field position.Get position CANSparkMax.getEncoder().getPosotion().Get velocity CANSparkMax.getEncoder().getVelocity().Set Follower CANSparkMax.follow() or CANSparkMax.follow(, ).NOTE Some motors, like NEO motors, have 3 wires AND what may look like a 4th wire, which is actually the encoder wire, inside the protective sleeve, there are 6 more wires.There are multiple control modes for different motors because some motors are BRUSHED and some are BRUSHLESS you can tell if it is brushed or brushless by counting the wires going into the motor from the controller.To intialize SparkMAX controller CANSparkMax = new CANSparkMax(, ).Set motor to follow another t(ControlMode.Follower, value) with value as the id of the other talon.Set motor absolute power t(ControlMode.PercentOutput, value) with value as double between -1 and 1.To initialize automatic deadband Motor.enableDeadbandElimination(true).To initialize motor WPI_TalonSRX Motor = new WPI_TalonSRX(6).To import control modes import .ControlMode.When given power, the motor will spin with speed proportional to the voltage and torque proportional to the current. Motors are one of the most common actuators and provide rotational motion.
