    • pushMotionProfileTrajectory

      Specified by:
      pushMotionProfileTrajectory in interface IMotorController
      Parameters:
      trajPt - to push into buffer. The members should be filled in with these values... targPos: servo position in sensor units. targVel: velocity to feed-forward in sensor units per 100ms. profileSlotSelect0 Which slot to get PIDF gains. PID is used for position servo. F is used as the Kv constant for velocity feed-forward. Typically this is hardcoded to the a particular slot, but you are free gain schedule if need be. Choose from [0,3] profileSlotSelect1 Which slot to get PIDF gains for auxiliary PId. This only has impact during MotionProfileArc Control mode. Choose from [0,1]. isLastPoint set to nonzero to signal motor controller to keep processing this trajectory point, instead of jumping to the next one when timeDurMs expires. Otherwise MP executer will eventually see an empty buffer after the last point expires, causing it to assert the IsUnderRun flag. However this may be desired if calling application never wants to terminate the MP. zeroPos set to nonzero to signal motor controller to "zero" the selected position sensor before executing this trajectory point. Typically the first point should have this set only thus allowing the remainder of the MP positions to be relative to zero. timeDur Duration to apply this trajectory pt. This time unit is ADDED to the exising base time set by configMotionProfileTrajectoryPeriod().
      Returns:
      CTR_OKAY if trajectory point push ok. ErrorCode if buffer is full due to kMotionProfileTopBufferCapacity.
    • startMotionProfile

      public ErrorCode startMotionProfile​(BufferedTrajectoryPointStream stream, int minBufferedPts, ControlMode motionProfControlMode)
      Simple one-shot firing of a complete MP. Starting in 2019, MPs can be fired by building a Buffered Trajectory Point Stream, and calling this routine. Once called, the motor controller software will automatically ... [1] Clear the firmware buffer of trajectory points. [2] Clear the underrun flags [3] Reset an index within the Buffered Trajectory Point Stream (so that the same profile can be run again and again). [4] Start a background thread to manage MP streaming (if not already running). [5a] If current control mode already matches motionProfControlMode, set MPE Output to "Hold". [5b] If current control mode does not matches motionProfControlMode, apply motionProfControlMode and set MPE Output to "Disable". [6] Stream the trajectory points into the device's firmware buffer. [7] Once motor controller has at least minBufferedPts worth in the firmware buffer, MP will automatically start (MPE Output set to "Enable"). [8] Wait until MP finishes, then transitions the Motion Profile Executor's output to "Hold". [9] IsMotionProfileFinished() will now return true. Calling application can use IsMotionProfileFinished() to determine when internal state machine reaches [7]. Calling application can cancel MP by calling set(). Otherwise do not call set() until MP has completed. The legacy API from previous years requires the calling application to pass points via the ProcessMotionProfileBuffer and PushMotionProfileTrajectory. This is no longer required if using this StartMotionProfile/IsMotionProfileFinished API.
      Parameters:
      stream - A buffer that will be used to stream the trajectory points. Caller can fill this container with the entire trajectory point, regardless of size.
      minBufferedPts - Minimum number of firmware buffered points before starting MP. Do not exceed device's firmware buffer capacity or MP will never fire (120 for Motion Profile, or 60 for Motion Profile Arc). Recommendation value for this would be five to ten samples depending on timeDur of the trajectory point.
      motionProfControlMode - Pass MotionProfile or MotionProfileArc.
      Returns:
      nonzero error code if operation fails.

      public boolean isMotionProfileFinished()
      Determine if running MP is complete. This requires using the StartMotionProfile routine to start the MP. That is because managing the trajectory points is now done in a background thread (if StartMotionProfile is called). If calling application uses the legacy API (more-complex buffering API) from previous years, than this API will not return true.
      Returns:
      true if MP was started using StartMotionProfile, and it has completed execution (MPE is now in "hold").
    • isMotionProfileTopLevelBufferFull

      Retrieve just the buffer full for the api-level (top) buffer. This routine performs no CAN or data structure lookups, so its fast and ideal if caller needs to quickly poll. Otherwise just use GetMotionProfileStatus.
      Specified by:
      isMotionProfileTopLevelBufferFull in interface IMotorController
      Returns:
      number of trajectory points in the top buffer.
    • processMotionProfileBuffer

      This must be called periodically to funnel the trajectory points from the API's top level buffer to the controller's bottom level buffer. Recommendation is to call this twice as fast as the execution rate of the motion profile. So if MP is running with 20ms trajectory points, try calling this routine every 10ms. All motion profile functions are thread-safe through the use of a mutex, so there is no harm in having the caller utilize threading.
      Specified by:
      processMotionProfileBuffer in interface IMotorController
    • getMotionProfileStatus

      Retrieve all status information. For best performance, Caller can snapshot all status information regarding the motion profile executer.
      Specified by:
      getMotionProfileStatus in interface IMotorController
      Parameters:
      statusToFill - Caller supplied object to fill. The members are filled, as follows... topBufferRem: The available empty slots in the trajectory buffer. The robot API holds a "top buffer" of trajectory points, so your applicaion can dump several points at once. The API will then stream them into the low-level buffer, allowing the motor controller to act on them. topBufferRem: The number of points in the top trajectory buffer. btmBufferCnt: The number of points in the low level controller buffer. hasUnderrun: Set if isUnderrun ever gets set. Can be manually cleared by clearMotionProfileHasUnderrun() or automatically cleared by startMotionProfile(). isUnderrun: This is set if controller needs to shift a point from its buffer into the active trajectory point however the buffer is empty. This gets cleared automatically when is resolved. activePointValid: True if the active trajectory point is not empty, false otherwise. The members in activePoint are only valid if this signal is set. isLast: is set/cleared based on the MP executer's current trajectory point's IsLast value. This assumes IsLast was set when PushMotionProfileTrajectory was used to insert the currently processed trajectory point. profileSlotSelect: The currently processed trajectory point's selected slot. This can differ in the currently selected slot used for Position and Velocity servo modes outputEnable: The current output mode of the motion profile executer (disabled, enabled, or hold). When changing the set() value in MP mode, it's important to check this signal to confirm the change takes effect before interacting with the top buffer.
      Returns:
      Error Code generated by function. 0 indicates no error.

      ordinal - 0 for remote sensor 0 and 1 for remote sensor 1.
      timeoutMs - Timeout value in ms. If nonzero, function will wait for config success and report an error if it times out. If zero, no blocking or checking is performed.
    • getFilterConfigs

      public void getFilterConfigs​(FilterConfiguration filter)
      Gets all filter persistant settings (overloaded so timeoutMs is 50 ms and ordinal is 0).
      Parameters:
      filter - Object with all of the filter persistant settings
    • baseConfigurePID

      protected ErrorCode baseConfigurePID​(BasePIDSetConfiguration pid, int pidIdx, int timeoutMs)
      Configures all base PID set persistant settings.
      Parameters:
      pid - Object with all of the base PID set persistant settings
      pidIdx - 0 for Primary closed-loop. 1 for auxiliary closed-loop.
      timeoutMs - Timeout value in ms. If nonzero, function will wait for config success and report an error if it times out. If zero, no blocking or checking is performed.
      Returns:
      Error Code generated by function. 0 indicates no error.
    • baseGetPIDConfigs

      protected void baseGetPIDConfigs​(BasePIDSetConfiguration pid, int pidIdx, int timeoutMs)
      Gets all base PID set persistant settings.
      Parameters:
      pid - Object with all of the base PID set persistant settings
      pidIdx - 0 for Primary closed-loop. 1 for auxiliary closed-loop.
      timeoutMs - Timeout value in ms. If nonzero, function will wait for config success and report an error if it times out. If zero, no blocking or checking is performed.
    • baseGetAllConfigs

      protected void baseGetAllConfigs​(BaseMotorControllerConfiguration allConfigs, int timeoutMs)
      Gets all base persistant settings.
      Parameters:
      allConfigs - Object with all of the base persistant settings
      timeoutMs - Timeout value in ms. If nonzero, function will wait for config success and report an error if it times out. If zero, no blocking or checking is performed.
