</div>
<div class="refsect1" title="Initialization">
<a id="idp54026688"></a>
<h2>Initialization</h2>
<p>
<span class="emphasis"><em>itimeout</em></span> -- integer number of seconds the
system should wait for all Wiimotes to be connected. If not
given it defaults to 10 seconds.
</p>
<p>
<span class="emphasis"><em>imaxnum</em></span> -- maximum number of Wiimotes to locate. If not
given it defaults to 4.

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

on failure.

Every control cycle each Wiimote is polled for its status and
position. These values are read by
the <span class="emphasis"><em>wiidata</em></span> opcode. The result returned is
1 in most cases, but will be zero if a Wiimote disconnects,
