Detailed Description

General internal wiiuse stuff.

Since Wiiuse is a library, wiiuse.h is a duplicate of the API header.

The code that would normally go in that file, but which is not needed by third party developers, is put here.

So wiiuse_internal.h is included by other files internally, wiiuse.h is included only here.

Function Documentation

int wiiuse_read_data_cb	(	struct wiimote_t *	wm,
		wiiuse_read_cb	read_cb,
		byte *	buffer,
		unsigned int	addr,
		unsigned short	len
	)

Read data from the wiimote (callback version).

Parameters:

	wm	Pointer to a wiimote_t structure.
	read_cb	Function pointer to call when the data arrives from the wiimote.
	buffer	An allocated buffer to store the data as it arrives from the wiimote. Must be persistent in memory and large enough to hold the data.
	addr	The address of wiimote memory to read from.
	len	The length of the block to be read.

The library can only handle one data read request at a time because it must keep track of the buffer and other events that are specific to that request. So if a request has already been made, subsequent requests will be added to a pending list and be sent out when the previous finishes.

int wiiuse_send	(	struct wiimote_t *	wm,
		byte	report_type,
		byte *	msg,
		int	len
	)

Send a packet to the wiimote.

Parameters:

	wm	Pointer to a wiimote_t structure.
	report_type	The report type to send (WIIMOTE_CMD_LED, WIIMOTE_CMD_RUMBLE, etc). Found in wiiuse.h
	msg	The payload.
	len	Length of the payload in bytes.

This function should replace any write()s directly to the wiimote device.

void wiiuse_send_next_pending_read_request

(

struct wiimote_t *

wm

)

Send the next pending data read request to the wiimote.

Parameters:

wm

Pointer to a wiimote_t structure.

See also:

wiiuse_read_data()

This function is not part of the wiiuse API.

int wiiuse_set_report_type

(

struct wiimote_t *

wm

)

Set the report type based on the current wiimote state.

Parameters:

wm

Pointer to a wiimote_t structure.

Returns:

The report type sent.

The wiimote reports formatted packets depending on the report type that was last requested. This function will update the type of report that should be sent based on the current state of the device.
