<h3>Summary</h3>
|
||
|
|
<div class=tooltipinfo>
|
||
|
|
<p>Play audio data provided by the Arduino sketch. This object provides
|
||
|
|
functions to allow the sketch code to push data into the audio system.</p>
|
||
|
|
</div>

<h3>Audio Connections</h3>

|

<tr class=top><th>Port</th><th>Purpose</th></tr>

<h3>Functions</h3>
|

|
|
<p class=func><span class=keyword>play</span>(int16);</p>
|
||
|
|
<p class=desc>not yet implemented
|
||
|
|
</p>
|
||
|
|
<p class=func><span class=keyword>play</span>(int16[], length);</p>
|
||
|
|
<p class=desc>not yet implemented
|
||
|
|
</p>
|
||
|
|
<p class=func><span class=keyword>getBuffer</span>();</p>
|
||
|
|
<p class=desc>Returns a pointer to an array of 128 int16. This buffer
|
||
|
|
is within the audio library memory pool, providing the most efficient
|
||
|
|
way to input data to the audio system. The buffer is likely to be
|
||
|
|
populated by previously used data, so the entire 128 words should be
|
||
|
|
written before calling playBuffer(). Only a single buffer should be
|
||
|
|
requested at a time. This function may return NULL if no memory is
|
||
|
|
available.
|
||
|
|
</p>
|
||
|
|
<p class=func><span class=keyword>playBuffer</span>();</p>
|
||
|
|
<p class=desc>Transmit the buffer previously obtained from getBuffer().
|
||
|
