Detailed Description

Class for getting information about an available CAN bus.

Constructor & Destructor Documentation

CANBus() [1/2]

constexpr ctre::phoenix6::CANBus::CANBus ( std::string_view canbus = "" )

inlineconstexpr

Creates a new CAN bus with the given name.

Parameters

canbus

Name of the CAN bus. Possible CAN bus strings are: "rio" for the native roboRIO CAN bus CANivore name or serial number SocketCAN interface (non-FRC Linux only) "*" for any CANivore seen by the program empty string (default) to select the default for the system: "rio" on roboRIO "can0" on Linux "*" on Windows

CANBus() [2/2]

ctre::phoenix6::CANBus::CANBus ( std::string_view canbus, char const * hootFilepath )

inline

Creates a new CAN bus with the given name, and loads an associated hoot file for replay (equivalent to HootReplay::LoadFile).

Only one hoot log may be replayed at a time. As a result, only one CAN bus should be constructed with a hoot file.

When using relative paths, the file path is typically relative to the top-level folder of the robot project.

Parameters

canbus	Name of the CAN bus. Possible CAN bus strings are: "rio" for the native roboRIO CAN bus CANivore name or serial number SocketCAN interface (non-FRC Linux only) "*" for any CANivore seen by the program empty string (default) to select the default for the system: "rio" on roboRIO "can0" on Linux "*" on Windows
hootFilepath	Path and name of the hoot file to load

Member Function Documentation

GetName()

constexpr std::string_view ctre::phoenix6::CANBus::GetName ( ) const

inlineconstexpr

Get the name used to construct this CAN bus.

Returns

Name of the CAN bus

GetStatus() [1/2]

CANBusStatus ctre::phoenix6::CANBus::GetStatus

(

)

const

Gets the status of the CAN bus, including the bus utilization and the error counters.

This can block for up to 0.001 seconds (1 ms).

Returns

Status of the CAN bus

GetStatus() [2/2]

static CANBusStatus ctre::phoenix6::CANBus::GetStatus ( std::string const & canbus )

inlinestatic

Gets the status of the CAN bus, including the bus utilization and the error counters.

Deprecated

The CANBus static methods are deprecated for removal in 2026. Construct a new CANBus instance and call GetStatus() instead.

Parameters

canbus

Name of the CAN bus

Returns

Status of the CAN bus

IsNetworkFD() [1/2]

bool ctre::phoenix6::CANBus::IsNetworkFD

(

)

const

Gets whether the CAN bus is a CAN FD network.

Returns

True if the CAN bus is CAN FD

IsNetworkFD() [2/2]

static bool ctre::phoenix6::CANBus::IsNetworkFD ( std::string const & canbus )

inlinestatic

Gets whether the CAN bus is a CAN FD network.

Deprecated

The CANBus static methods are deprecated for removal in 2026. Construct a new CANBus instance and call IsNetworkFD() instead.

Parameters

canbus

Name of the CAN bus

Returns

True if the CAN bus is CAN FD
