wiiconnect — Reads data from a number of external Nintendo Wiimote controllers.
Initialization
itimeout -- integer number of seconds the system should wait for all Wiimotes to be connected. If not given it defaults to 10 seconds.

Please note that these opcodes are currently only supported on Linux. |
Every control cycle each Wiimote is polled for its status and position. These values are read by the wiidata opcode. The result returned is 1 in most cases, but will be zero if a Wiimote disconnects,
Example
Here is an example of the wii opcodes. It uses the file wii.csd.
