Detailed Description

Follow the differential motor output of another Talon.

If Talon is in torque control, the differential torque is copied - which will increase the total torque applied. If Talon is in duty cycle output control, the differential duty cycle is matched. If Talon is in voltage output control, the differential motor voltage is matched. Motor direction either matches leader's configured direction or opposes it based on the MotorAlignment.

The leader must enable its DifferentialOutput status signal. The update rate of the status signal determines the update rate of the follower's output and should be no slower than 20 Hz.

◆ DifferentialFollower()

ctre::phoenix6::controls::DifferentialFollower::DifferentialFollower ( int LeaderID,
signals::MotorAlignmentValue MotorAlignment )
inlineconstexpr

Follow the differential motor output of another Talon.

If Talon is in torque control, the differential torque is copied - which will increase the total torque applied. If Talon is in duty cycle output control, the differential duty cycle is matched. If Talon is in voltage output control, the differential motor voltage is matched. Motor direction either matches leader's configured direction or opposes it based on the MotorAlignment.

The leader must enable its DifferentialOutput status signal. The update rate of the status signal determines the update rate of the follower's output and should be no slower than 20 Hz.

Parameters
LeaderIDDevice ID of the differential leader to follow.
MotorAlignmentSet to Aligned for motor invert to match the leader's configured Invert - which is typical when leader and follower are mechanically linked and spin in the same direction. Set to Opposed for motor invert to oppose the leader's configured Invert - this is typical where the leader and follower mechanically spin in opposite directions.

Member Function Documentation

◆ GetControlInfo()

std::map< std::string, std::string > ctre::phoenix6::controls::DifferentialFollower::GetControlInfo ( ) const
overridevirtual

Gets information about this control request.

Returns
Map of control parameter names and corresponding applied values

Implements ctre::phoenix6::controls::ControlRequest.

◆ GetName()

std::string_view ctre::phoenix6::controls::DifferentialFollower::GetName ( ) const
inlineconstexproverridevirtual

Gets the name of this control request.

Returns
Name of the control request

Implements ctre::phoenix6::controls::ControlRequest.

◆ ToString()

std::string ctre::phoenix6::controls::DifferentialFollower::ToString ( ) const
overridevirtual

Returns a string representation of the object.

Returns
a string representation of the object.

Implements ctre::phoenix6::controls::ControlRequest.

◆ WithLeaderID()

DifferentialFollower & ctre::phoenix6::controls::DifferentialFollower::WithLeaderID ( int newLeaderID)
inlineconstexpr

Modifies this Control Request's LeaderID parameter and returns itself for method-chaining and easier to use request API.

Device ID of the differential leader to follow.

Parameters
newLeaderIDParameter to modify
Returns
Itself

◆ WithMotorAlignment()

DifferentialFollower & ctre::phoenix6::controls::DifferentialFollower::WithMotorAlignment ( signals::MotorAlignmentValue newMotorAlignment)
inlineconstexpr

Modifies this Control Request's MotorAlignment parameter and returns itself for method-chaining and easier to use request API.

Set to Aligned for motor invert to match the leader's configured Invert - which is typical when leader and follower are mechanically linked and spin in the same direction. Set to Opposed for motor invert to oppose the leader's configured Invert - this is typical where the leader and follower mechanically spin in opposite directions.

Parameters
newMotorAlignmentParameter to modify
Returns
Itself

◆ WithUpdateFreqHz()

DifferentialFollower & ctre::phoenix6::controls::DifferentialFollower::WithUpdateFreqHz ( units::frequency::hertz_t newUpdateFreqHz)
inlineconstexpr

Sets the frequency at which this control will update.

This is designated in Hertz, with a minimum of 20 Hz (every 50 ms) and a maximum of 1000 Hz (every 1 ms). Some update frequencies are not supported and will be promoted up to the next highest supported frequency.

If this field is set to 0 Hz, the control request will be sent immediately as a one-shot frame. This may be useful for advanced applications that require outputs to be synchronized with data acquisition. In this case, we recommend not exceeding 50 ms between control calls.

Parameters
newUpdateFreqHzParameter to modify
Returns
Itself
