Member Function Documentation

◆ GetAppliedControl() [1/2]

std::shared_ptr< controls::ControlRequest > ctre::phoenix6::hardware::ParentDevice::GetAppliedControl ( )

inline

Get the latest applied control.

Caller can cast this to the derived class if they know its type. Otherwise, use controls::ControlRequest::GetControlInfo to get info out of it.

This returns a shared pointer to avoid becoming a dangling pointer due to parallel operations changing the underlying data. Make sure to save the shared_ptr to a variable before chaining function calls, otherwise the data may be freed early.

Returns: Latest applied control

◆ GetAppliedControl() [2/2]

std::shared_ptr< const controls::ControlRequest > ctre::phoenix6::hardware::ParentDevice::GetAppliedControl ( ) const

inline

Get the latest applied control.

Caller can cast this to the derived class if they know its type. Otherwise, use controls::ControlRequest::GetControlInfo to get info out of it.

This returns a shared pointer to avoid becoming a dangling pointer due to parallel operations changing the underlying data. Make sure to save the shared_ptr to a variable before chaining function calls, otherwise the data may be freed early.

Returns: Latest applied control

◆ GetDeviceHash()

uint64_t ctre::phoenix6::hardware::ParentDevice::GetDeviceHash ( ) const

inline

Gets a number unique for this device's hardware type and ID.

This number is not unique across networks.

This can be used to easily reference hardware devices on the same network in collections such as maps.

Returns: Hash of this device.

◆ GetDeviceID()

int ctre::phoenix6::hardware::ParentDevice::GetDeviceID ( ) const

inline

Returns: The device ID of this device [0,62].

◆ GetGenericSignal()

StatusSignal< double > & ctre::phoenix6::hardware::ParentDevice::GetGenericSignal	(	uint32_t	signal,
		bool	refresh = true )

inline

This is a reserved routine for internal testing.

Use the other get routines to retrieve signal values.

Parameters

signal	Signal to get.
refresh	Whether to refresh

Returns: StatusSignalValue holding value

◆ GetNetwork()

const std::string & ctre::phoenix6::hardware::ParentDevice::GetNetwork ( ) const

inline

Returns: Name of the network this device is on.

inline

Returns whether the device is still connected to the robot.

This is equivalent to refreshing and checking the latency of the Version status signal.

Parameters

maxLatencySeconds The maximum latency of the Version status signal before the device is reported as disconnected

Returns: true if the device is connected

◆ LookupDimensionlessStatusSignal()

template<typename T , typename U >

◆ OptimizeBusUtilization()

ctre::phoenix::StatusCode ctre::phoenix6::hardware::ParentDevice::OptimizeBusUtilization	(	units::frequency::hertz_t	optimizedFreqHz = 0_Hz,
		units::time::second_t	timeoutSeconds = 100_ms )

Optimizes the device's bus utilization by reducing the update frequencies of its status signals.

All status signals that have not been explicitly given an update frequency using BaseStatusSignal::SetUpdateFrequency will be disabled. Note that if other status signals in the same status frame have been given an update frequency, the update frequency will be honored for the entire frame.

This function only needs to be called once on this device in the robot program. Additionally, this method does not necessarily need to be called after setting the update frequencies of other signals.

To restore the default status update frequencies, call ResetSignalFrequencies. Alternatively, remove this method call, redeploy the robot application, and power-cycle the device on the bus. The user can also override individual status update frequencies using BaseStatusSignal::SetUpdateFrequency.

Parameters

optimizedFreqHz	The update frequency to apply to the optimized status signals. A frequency of 0 Hz (default) will turn off the signals. Otherwise, the minimum supported signal frequency is 4 Hz.
timeoutSeconds	Maximum amount of time to wait for each status frame when performing the action

Returns: Status code of the first failed update frequency set call, or OK if all succeeded
