Please note this is an internal function and should not be used directly.

Parameters:

link	the nunchuck port number
_reg	the register to read
data	the tByteArray to hold the returned data

Returns:: true if no error occured, false if it did

Definition at line 172 of file dexterind-nxtchuck.h.

bool _NXTChuckInit ( tSensors link )

It's a nunchuck, innit? Initialise the nunchuck sensor.

Please note that this is an internal function and should not called directly.

Parameters:

link	the NXTChuck port number

Returns:: true if no error occured, false if it did

Definition at line 153 of file dexterind-nxtchuck.h.

bool NXTChuckReadClassicController	(	tSensors	link,
		tClassicCtrl &	controller
	)

Parameters:

link	the nunchuck port number
controller	the tClassicCtrl that holds the Classic Controller related data.

Returns:: true if no error occured, false if it did

Definition at line 274 of file dexterind-nxtchuck.h.

bool NXTChuckreadIdent	(	tSensors	link,
		tNunchuck &	nunchuck
	)

Identify the type of nunchuck sensor connected to the NXT.

Parameters:

link	the nunchuck port number
nunchuck	the tNunchuck that holds the nunchuck related data.

Returns:: true if no error occured, false if it did

Examples:: dexterind-nxtchuck-test1.c.

Definition at line 201 of file dexterind-nxtchuck.h.

bool NXTChuckreadSensor	(	tSensors	link,
		tNunchuck &	nunchuck
	)

Read the data from the nunchuck.

Parameters:

link	the nunchuck port number
nunchuck	the tNunchuck that holds the nunchuck related data.

Returns:: true if no error occured, false if it did

Examples:: dexterind-nxtchuck-test1.c.
