| or another I2S device.</p> | |||

| </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 align=center><img src="audioshield_inputs.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> | |||
