wiiconnect — Reads data from a number of external Nintendo Wiimote controllers.


Opens and at control-rate polls up to four external Nintendo Wiimote controllers.


ires wiiconnect [itimeout, imaxnum]


itimeout -- integer number of seconds the system should wait for all Wiimotes to be connected. If not given it defaults to 10 seconds.

imaxnum -- maximum number of Wiimotes to locate. If not given it defaults to 4.

Initially each Wiimote has its numeric allocation indicated by lighting one of the four LEDs.

ires -- return value is 1 if sucess or zero on failure.


[Note] Note

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,


Here is an example of the wii opcodes. It uses the file wii.csd.
