Constructor & Destructor Documentation

Talon::Talon ( uint32_t  channel )

explicit

Constructor that assumes the default digital module.

Parameters

channel

The PWM channel on the digital module that the Talon is attached to.

Definition at line 41 of file Talon.cpp.

Talon::Talon	(	uint8_t	moduleNumber,
		uint32_t	channel
	)

Constructor that specifies the digital module.

Parameters

moduleNumber	The digital module (1 or 2).
channel	The PWM channel on the digital module that the Talon is attached to (1..10).

Definition at line 52 of file Talon.cpp.

Member Function Documentation

void Talon::Disable ( )

virtual

Common interface for disabling a motor.

Implements SpeedController.

Definition at line 88 of file Talon.cpp.

float Talon::Get ( )

virtual

Get the recently set value of the PWM.

Returns

The most recently set value for the PWM between -1.0 and 1.0.

Implements SpeedController.

Definition at line 80 of file Talon.cpp.

void Talon::PIDWrite ( float  output )

virtual

Write out the PID value as seen in the PIDOutput base object.

Parameters

output

Write out the PWM value as was found in the PIDController

Implements PIDOutput.

Definition at line 98 of file Talon.cpp.

void Talon::Set ( float  speed, uint8_t  syncGroup = 0  )

virtual

Set the PWM value.

The PWM value is set using a range of -1.0 to 1.0, appropriately scaling the value for the FPGA.

Parameters

speed	The speed value between -1.0 and 1.0 to set.
syncGroup	Unused interface.

Implements SpeedController.
