Padscore.rpl

This library handles communication with controllers other than the Gamepad. It includes functions for the Wii Remote (WPAD), the Wii Balance Board (WBC), and a higher-level abstraction (KPAD). Unlike vpad.rpl for the Gamepad, this library appears to be optional, being loaded much closer to the application binary.

Functions

Wii Remote

Name	Prototype	Description
WPADInit	void WPADInit(void);	Initializes the library
WPADShutdown	void WPADShutdown(void);	Cleans up after the library
WPADProbe	int WPADProbe(int chan, void * buffer);	This function checks if there is a controller connected to chan (between 0 and 3 for four total controllers). Possible return values include 0 (connection success), -1 (remote not connnected) and -2 (remote is pairing with the console). The values will sometimes flicker due to connection issues with the controller. Be sure to call this BEFORE WPADRead so that you can avoid reading fake data from disconnected controllers.
WPADRead	int WPADRead(int chan, void *buffer);	Stores raw controller data for the specified Wii Remote in buffer
WPADIsMotorEnabled	bool WPADIsMotorEnabled(void);	Get's the status of the WPAD motor
WPADGetAcceptConnection	bool WPADGetAcceptConnection(void);	Returns true if we allow new wpad's to connect
WPADSetAcceptConnection	bool WPADSetAcceptConnection(bool acceptConnections);	Set's whenever or not we allow new connectins

Structures

Wii Remote Data

Can be gotten using WPADRead().
