<h3>Summary</h3>
|
|
<div class=tooltipinfo>
|
|
<p>Control the AK4558 chip on the <a href="https://hackaday.io/project/8567-hifi-audio-codec-module" target="_blank">HiFi Audio CODEC Module</a>
|
|
in slave mode, where the Teensy controls all I2S timing.</p>
|
|
</div>
|
|
<h3>Audio Connections</h3>
|
|
<p>This object has no audio inputs or outputs. Separate I2S objects
|
|
are used to send and receive audio data.
|
|
</p>
|
|
<h3>Functions</h3>
|
|
<p class=func><span class=keyword>enable</span>();</p>
|
|
<p class=desc>Enables the CODEC to work with 44.1 KHz - 16 bit data. This function does not enable the ADC/DAC modules.
|
|
</p>
|
|
<p class=func><span class=keyword>enableIn</span>();</p>
|
|
<p class=desc>Enables the ADC module.
|
|
</p>
|
|
<p class=func><span class=keyword>enableOut</span>();</p>
|
|
<p class=desc>Enables the DAC module.
|
|
</p>
|
|
<p class=func><span class=keyword>disable</span>();</p>
|
|
<p class=desc>Disables the ADC and the DAC modules.
|
|
</p>
|
|
<p class=func><span class=keyword>disableIn</span>();</p>
|
|
<p class=desc>Disable the ADC module.
|
|
</p>
|
|
<p class=func><span class=keyword>disableOut</span>();</p>
|
|
<p class=desc>Disable the DAC module.
|
|
</p>
|
|
<p class=func><span class=keyword>volume</span>(level);</p>
|
|
<p class=desc>Accepts a float in range 0.0-1.0 and sets the line output volume accordingly.
|
|
</p>
|
|
<p class=func><span class=keyword>volumeLeft</span>(level);</p>
|
|
<p class=desc>Accepts a float in range 0.0-1.0 and sets the left line output volume accordingly.
|
|
</p>
|
|
<p class=func><span class=keyword>volumeRight</span>(level);</p>
|
|
<p class=desc>Accepts a float in range 0.0-1.0 and sets the right line output volume accordingly.
|
|
</p>
|
|
<p class=func><span class=keyword>inputLevel</span>(level);</p>
|
|
<p class=desc>NOT SUPPORTED BY THE AK4558
