<h3>Summary</h3>
|
||
|
|
<div class=tooltipinfo>
|
||
|
|
<p>Control the TLV320AIC3206 chip that is at the heart of the Tympan audio interface.
|
||
|
|
The TLV320AIC3206 is used in slave mode, where Teensy controls
|
||
|
|
all clocks and I2S timing in order to get the audio data to and from the chip.

<h3>Audio Connections</h3>
|
||
|
|
<p>This object has no audio inputs or outputs. Separate i2s objects
|
||
|
|
are used to send and receive audio data. I2S master mode objects
|
||
|
|
must be used, because this object configures the TLV320AIC3206 in slave
|
||
|
|
mode, where it depends on Teensy to provide all I2S clocks.
|
||
|
|
This object controls
|
||
|
|
how the TLV320AIC3206 will use those I2S audio streams.</p>
|
||
|

<h3>Functions</h3>
|
||
|
|
<p>These are the most commonly used TLV320AIC3206 functions.</p>
|
||
|
|
<p class=func><span class=keyword>enable</span>();</p>
|
||
|
|
<p class=desc>Start the TLV320AIC3206 with default configuration settings.
|
||
|
|
This function should be called first.
|
||
|
|
</p>
|
||
|
|
<p class=func><span class=keyword>volume_dB</span>(float value_dB);</p>
|
||
|
|
<p class=desc>Set DAC output volume level. Range is -63.6dB to +24dB, in
|
||
|
|
0.5dB steps. Decimal values that are not increments of 0.5 will be rounded
|
||
|
|
to the nearest step.
|
||
|
|
</p>
|
||
|
|
<p class=func><span class=keyword>inputSelect</span>(int value);</p>
|
||
|
|
<p class=desc>Select which input to use:</p>
|
||
|
|
<p class=desc>TYMPAN_INPUT_JACK_AS_MIC - Use Mic Jack, turn MIC BIAS on @2.5V</p>
|
||
|
|
<p class=desc>TYMPAN_INPUT_JACK_AS_LINEIN - Use Mic Jack as Line In - MIC BIAS off</p>
|
||
|
|
<p class=desc>TYMPAN_INPUT_ON_BOARD_MIC - use on-board microphones, BIAS off</p>
|
||
|
|
<p class=desc>TYMPAN_INPUT_LINE_IN - use the IN1 solder pads on the TYMPAN</p>
|
||
|
|
<p class=func><span class=keyword>setInputGain_dB</span>(float value_dB);</p>
|
||
|
|
<p class=desc>When using the microphone input, set the amplifier gain.
|
||
|
|
Range is 0dB to 47.5dB in 0.5dB steps. Decimal values that are not
|
||
|
|
increments of 0.5 will be rounded to the nearest step.
