Parameters

controlWord the control word (out)

Returns: the error code, or 0 for success

◆ HAL_GetJoystickAxes()

int32_t HAL_GetJoystickAxes	(	int32_t	joystickNum,
		HAL_JoystickAxes *	axes

Returns: the error code, or 0 for success

◆ HAL_GetJoystickAxisType()

int32_t HAL_GetJoystickAxisType	(	int32_t	joystickNum,
		int32_t	axis
	)

Gets the type of a specific joystick axis.

Parameters

joystickNum	the joystick number
axis	the axis number

Returns: the enumerated axis type

◆ HAL_GetJoystickButtons()

int32_t HAL_GetJoystickButtons	(	int32_t	joystickNum,
		HAL_JoystickButtons *	buttons
	)

Gets the buttons of a specific joystick.

Parameters

Returns: the error code, or 0 for success

◆ HAL_GetJoystickDescriptor()

int32_t HAL_GetJoystickDescriptor	(	int32_t	joystickNum,
		HAL_JoystickDescriptor *	desc
	)

Retrieves the Joystick Descriptor for particular slot.

Parameters

	joystickNum	the joystick number
[out]	desc	descriptor (data transfer object) to fill in. desc is filled in regardless of success. In other words, if descriptor is not available, desc is filled in with default values matching the init-values in Java and C++ Driver Station for when caller requests a too-large joystick index.

Returns: error code reported from Network Comm back-end. Zero is good, nonzero is bad.

◆ HAL_GetJoystickIsXbox()

HAL_Bool HAL_GetJoystickIsXbox ( int32_t joystickNum )

Gets whether a specific joystick is considered to be an XBox controller.

Parameters

joystickNum the joystick number

Returns: true if xbox, false otherwise

◆ HAL_GetJoystickName()

char * HAL_GetJoystickName ( int32_t joystickNum )

Gets the name of a joystick.

The returned array must be freed with HAL_FreeJoystickName.

Will be null terminated.

Parameters

joystickNum the joystick number

Returns: the joystick name

Parameters

[in] info the match info (output)

Returns: the error code, or 0 for success

◆ HAL_GetMatchTime()

double HAL_GetMatchTime ( int32_t * status )

Returns the approximate match time.

The FMS does not send an official match time to the robots, but does send an approximate match time. The value will count down the time remaining in the current period (auto or teleop).

Warning: This is not an official time (so it cannot be used to dispute ref calls or guarantee that a function will trigger before the match ends).

The Practice Match function of the DS approximates the behavior seen on the field.

[out] status the error code, or 0 for success

Returns: time remaining in current match period (auto or teleop)

◆ HAL_ObserveUserProgramAutonomous()

void HAL_ObserveUserProgramAutonomous ( void )

Sets the autonomous enabled flag in the DS.

This is used for the DS to ensure the robot is properly responding to its state request. Ensure this gets called about every 50ms, or the robot will be disabled by the DS.

◆ HAL_ObserveUserProgramDisabled()

void HAL_ObserveUserProgramDisabled ( void )

Sets the disabled flag in the DS.

This is used for the DS to ensure the robot is properly responding to its state request. Ensure this gets called about every 50ms, or the robot will be disabled by the DS.
