<h3>Summary</h3>
<p>Receive 16 bit stereo audio from an I2S device using I2S slave mode.</p>
<h3>Audio Connections</h3>
<table class=doc align=center cellpadding=3>
<tr class=top><th>Port</th><th>Function</th></tr>
<tr class=odd><td align=center>Out 0</td><td>Left Channel</td></tr>
<tr class=odd><td align=center>Out 1</td><td>Right Channel</td></tr>
</table>
<h3>Functions</h3>
<p>This object has no functions to call from the Arduino sketch. It
simply streams data from the I2S hardware to its 2 output ports.</p>
<h3>Hardware</h3>
<p>The I2S signals are used in "slave" mode, where the I2S device controls
data timing.</p>
<table class=doc align=center cellpadding=3>
<tr class=top><th>Pin</th><th>Signal</th><th>Direction</th></tr>

<tr class=odd><td align=center>13</td><td>RX</td><td>Input</td></tr>
<tr class=odd><td align=center>23</td><td>LRCLK</td><td>Input</td></tr>
</table>
<p>Slave mode I2S <b>should not used in the same project as ADC, DAC and
PWM</b> signals. Differences in timing between the I2S device and
Teensy's clock can cause occasional audio glitches when I2S slave mode
is used together with other input or output objects based on Teensy's
timing.</p>
