Detailed Description

Alias for counter class. Implement the gear tooth sensor supplied by FIRST. Currently there is no reverse sensing on the gear tooth sensor, but in future versions we might implement the necessary timing in the FPGA to sense direction.

Constructor & Destructor Documentation

GearTooth::GearTooth	(	unsigned	channel,
		bool	directionSensitive = true
	)

Construct a GearTooth sensor given a channel.

The default module is assumed.

Parameters:

	channel	The GPIO channel on the digital module that the sensor is connected to.
	directionSensitive	Enable the pulse length decoding in hardware to specify count direction.

GearTooth::GearTooth	(	unsigned	slot,
		unsigned	channel,
		bool	directionSensitive = true
	)

Construct a GearTooth sensor given a channel and module.

Parameters:

	slot	The slot in the chassis that the digital module is plugged in to.
	channel	The GPIO channel on the digital module that the sensor is connected to.
	directionSensitive	Enable the pulse length decoding in hardware to specify count direction.

GearTooth::GearTooth	(	DigitalSource *	source,
		bool	directionSensitive = true
	)

Construct a GearTooth sensor given a digital input. This should be used when sharing digial inputs.

Parameters:

	source	An object that fully descibes the input that the sensor is connected to.
	directionSensitive	Enable the pulse length decoding in hardware to specify count direction.
