This file is an example of how to use the wiiuse library.

Function Documentation

handle_ctrl_status()

void handle_ctrl_status

(

struct wiimote_t *

wm

)

Callback that handles a controller status event.

Parameters

wm	Pointer to a wiimote_t structure.
attachment	Is there an attachment? (1 for yes, 0 for no)
speaker	Is the speaker enabled? (1 for yes, 0 for no)
ir	Is the IR support enabled? (1 for yes, 0 for no)
led	What LEDs are lit.
battery_level	Battery level, between 0.0 (0%) and 1.0 (100%).

This occurs when either the controller status changed or the controller status was requested explicitly by wiiuse_status().

One reason the status can change is if the nunchuk was inserted or removed from the expansion port.

handle_disconnect()

void handle_disconnect

(

wiimote *

wm

)

Callback that handles a disconnection event.

Parameters

wm	Pointer to a wiimote_t structure.

This can happen if the POWER button is pressed, or if the connection is interrupted.

handle_event()

void handle_event

(

struct wiimote_t *

wm

)

Callback that handles an event.

Parameters

wm	Pointer to a wiimote_t structure.

This function is called automatically by the wiiuse library when an event occurs on the specified wiimote.

handle_read()

void handle_read	(	struct wiimote_t *	wm,
		byte *	data,
		unsigned short	len
	)

Callback that handles a read event.

Parameters

wm	Pointer to a wiimote_t structure.
data	Pointer to the filled data block.
len	Length in bytes of the data block.

This function is called automatically by the wiiuse library when the wiimote has returned the full data requested by a previous call to wiiuse_read_data().

You can read data on the wiimote, such as Mii data, if you know the offset address and the length.

The data pointer was specified on the call to wiiuse_read_data(). At the time of this function being called, it is not safe to deallocate this buffer.

main()

int main	(	int	argc,
		char **	argv
	)

main()

Connect to up to two wiimotes and print any events that occur on either device.
