|chan||One of the
|callback||Callback function to notify about the result. Notification processing is omitted if
|WPAD_ERR_NONE||The WPAD library received the command.|
|WPAD_ERR_NO_CONTROLLER||The connection was broken.||WPAD_ERR_BUSY||The WPAD library was unable to receive the command. Wait a short time and call the function again.|
Controls the specified Wii Balance Board. This function registers Wii Balance Board control commands with the WPAD library. The WPAD library processes registered commands when other commands are not running.
The different commands are defined as follows.
|WPAD_BLCMD_OFF||Stops the Wii Balance Board.|
|WPAD_BLCMD_ON||Starts the Wii Balance Board.|
|WPAD_BLCMD_UPDATE_TEMP||Updates the temperature value for the Wii Balance Board.|
When a callback function has been set, the callback function is called together with the processing result. When the return value is
WPAD_ERR_NONE, the callback function is called when the process is completed. Otherwise, it is called before the function escapes. The following error codes are passed to the callback function.
|WPAD_ERR_NONE||The command was processed normally.|
|WPAD_ERR_BUSY||The WPAD library was unable to receive the command. Wait a short time and call the function again.|
|WPAD_ERR_TRANSFER||A communication error prevented normal processing of the command.|
|WPAD_ERR_NO_CONTROLLER||The connection was broken.|
|Background||Do not call this function from the background.|
|Interrupt handler||Do not call this function from any interrupt handler.|
|Exception handler||Do not call this function from any exception handler.|
|Multiple Cores||Do not call this function from more than one Core.|

2009/09/24 Explained the timing of the call to the callback function.
2007/09/11 Removed the command to obtain remaining battery power and added the command to obtain temperature.
