	<h3>Summary</h3>
	<div class=tooltipinfo>
	<p>Receive 16 bit stereo audio from the
	<a href="http://www.pjrc.com/store/teensy3_audio.html" target="_blank">audio shield</a>
		or another I2S device, using I2S master mode.</p>

	<h3>Audio Connections</h3>

	<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 align=center><img src="img/audioshield_backside.jpg"></p>
	<p>The I2S signals are used in "master" mode, where Teensy creates
		all 3 clock signals and controls all 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>9</td><td>BCLK</td><td>Output</td></tr>
		<tr class=odd><td align=center>11</td><td>MCLK</td><td>Output</td></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>Output</td></tr>
	</table>
	<p>Audio from
		master mode I2S may be used in the same project as ADC, DAC and
		PWM signals, because all remain in sync to Teensy's timing</p>

	<h3>Notes</h3>
	<p>Normally, this object is used with the Audio Shield, which
		is controlled separately by the "sgtl5000" object.</p>
	<p>Only one I2S input and one I2S output object may be used.  Master
		and slave modes may not be mixed (both must be of the same type).
	</p>
	<p>I2S master objects can be used together with non-I2S input and output
		objects, for simultaneous audio streaming on different hardware.</p>
