Detailed Description

Static class for controlling the Phoenix 6 signal logger.

This logs all the signals from the CAN buses into .hoot files. Each file name starts with the CANivore serial number or "rio" for the roboRIO CAN bus, followed by the timestamp. In the header of a hoot file, the CANivore name and firmware version are logged in plain text.

During an FRC match, the log file will be renamed to include the event name, match type, and match number at the start of the file name. The match type will be 'P' for practice matches, 'Q' for qualification matches, and 'E' for elimination matches.

Member Function Documentation

◆ EnableAutoLogging()

static ctre::phoenix::StatusCode ctre::phoenix6::SignalLogger::EnableAutoLogging ( bool enable )

static

Enables or disables auto logging.

Auto logging is only supported on the roboRIO. When auto logging is enabled, logging is started at the beginning of an FRC match and stopped at the end.

Parameters

enable Whether to enable auto logging

Returns: Status of auto logging enable/disable

◆ SetPath()

static ctre::phoenix::StatusCode ctre::phoenix6::SignalLogger::SetPath ( const char * path )

static

Sets the destination for logging, restarting logger if the path changed.

If this is not called or the path is left empty, the default path will be used. The default path on the roboRIO is a logs folder on the first USB flash drive found, or /home/lvuser/logs if none is available. The default path on all other platforms is a logs folder in the current working directory.

Typical use for this routine is to use a removable USB flash drive for logging.

Parameters

path	Folder path for the log files; path must exist

Returns: Status of setting the path and restarting the log

◆ Start()

static ctre::phoenix::StatusCode ctre::phoenix6::SignalLogger::Start ( )

static

Starts logging status signals.

Starts regardless of auto logging status.

If using a roboRIO 1, we recommend setting the logging path to an external drive using SetPath to avoid running out of internal storage space.

If auto logging is enabled, the log will be stopped at the end of the match.

Returns: Status of starting the logger

◆ Stop()

static ctre::phoenix::StatusCode ctre::phoenix6::SignalLogger::Stop ( )

static

Stops logging status signals.

Stops regardless of auto logging status.

Returns: Status of stopping the logger

◆ WriteBoolean()

	)

inlinestatic

Writes the boolean to the log file.

Parameters

name	Name of the signal
