Function Documentation

void debugIR ( tByteArray & data )

Print out the buffer in question to the screen using the following format:

0 11001100 0xCC

It pauses for 10 seconds between each screenful, accompanied by a beep.

Note: this function is only available when driver is compiled with _DEBUG_DRIVER_ defined.

Parameters:

data	the data to be displayed as binary/hex numbers

Definition at line 179 of file hitechnic-irlink.h.

void decToBin	(	int	number,
		int	length,
		string &	output
	)

Returns a binary representation in a string of an int with specified length

Note: this function is only available when driver is compiled with _DEBUG_DRIVER_ defined.

Parameters:

number	the number to be converted to a binary representation
length	number of bits to convert
output	the number converted to binary representation

Definition at line 156 of file hitechnic-irlink.h.

void encodeBuffer	(	tByteArray &	iBuffer,
		tByteArray &	oBuffer
	)

Encode the input buffer into a special format for the IRLink.

Note: this is an internal function and should not be called directly.

Parameters:

iBuffer	the data that is be encoded
oBuffer	output buffer for encoded data

Definition at line 344 of file hitechnic-irlink.h.

void PFcomboDirectMode	(	tSensors	link,
		int	channel,
		eCDMMotorCommand	_motorB,
		eCDMMotorCommand	_motorA
	)

Control two motors using the ComboDirectMode. This mode does not allow for fine grained speed control.

Parameters:

link	the sensor port number
channel	the channel of the receiver we wish to communicate with, numbered 0-3
_motorB	the command to be sent to Motor B
_motorA	the command to be sent to Motor A

Examples:: hitechnic-irlink-test1.c.

Definition at line 204 of file hitechnic-irlink.h.

void PFcomboPwmMode	(	tSensors	link,
		int	channel,
		ePWMMotorCommand	_motorB,
		ePWMMotorCommand	_motorA
	)

Control two motors using the ComboPWMMode. This mode allows for fine grained speed control.

Parameters:

link	the sensor port number
channel	the channel of the receiver we wish to communicate with, numbered 0-3
_motorB	the command to be sent to Motor B
_motorA	the command to be sent to Motor A

Examples:: hitechnic-irlink-test1.c.

Definition at line 249 of file hitechnic-irlink.h.

void PFMotor	(	tPFmotor	pfmotor,
		ePWMMotorCommand	_motorCmd
	)

Control one motor with no timeout. This mode allows for fine grained speed control.

Parameters:

pfmotor	the motor to which to send the command
_motorCmd	the command to send to the motor, 0-15

Examples:: hitechnic-irlink-test1.c.

Definition at line 332 of file hitechnic-irlink.h.

void PFsinglePinOutputMode	(	tSensors	link,
		ubyte	channel,
		ubyte	_motor,
		ePWMMotorCommand	_motorCmd
	)

Control one motor with no timeout. This mode allows for fine grained speed control.

Parameters:

link	the sensor port number
channel	the channel of the receiver we wish to communicate with, numbered 0-3
_motor	the motor to be controlled, 0 or 1, for A or B
_motorCmd	the command to send to the motor, 0-15

Definition at line 295 of file hitechnic-irlink.h.

void transmitIR	(	tSensors	link,
		tByteArray &	oBuffer,
		int	channel
	)

Send the command to the IRLink Sensor for transmission.

Note: this is an internal function and should not be called directly. If the driver is compiled with _DEBUG_DRIVER_, this function will call debugIR() prior to transmitting the data for debugging purposes.

Parameters:

link	the sensor port number
oBuffer	the data that is be transmitted
channel	the channel number of the receiver
