&lt;p&gt;&amp;nbsp;No, I think you&amp;#39;re good for I2S.&lt;/p&gt;
[quote user=""] how do I determine the frequency that i need for the lrclk and the bclk?&amp;nbsp;[/quote]
&lt;p&gt;&amp;nbsp;That depends on the signal sample rate of the signal and the I2S&amp;#39;s&amp;nbsp;&lt;a title="  Electrical specification  " href="https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf52832.ps.v1.1/i2s.html?cp=4_2_0_43_10#unique_1928782723"&gt;Electrical specification&lt;/a&gt;.&amp;nbsp;&lt;/p&gt;
[quote user=""]also how do I program the nrf52832 to transfer data over i2s as a slave?[/quote]
&lt;p&gt;&amp;nbsp;First you read&amp;nbsp;&lt;a href="https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf52832.ps.v1.1/i2s.html?cp=4_2_0_43#concept_z2v_24y_vr"&gt;I2S — Inter-IC sound interface&lt;/a&gt;, then the&amp;nbsp;&lt;a title="I2S driver" href="https://infocenter.nordicsemi.com/topic/sdk_nrf5_v17.0.2/group__nrfx__i2s.html?cp=7_1_6_8_0_15_1"&gt;I2S driver&lt;/a&gt;&amp;nbsp;API doc, then you try the&amp;nbsp;&lt;a title="I2S Loopback Example" href="https://infocenter.nordicsemi.com/topic/sdk_nrf5_v17.0.2/i2s_example_loopback.html?cp=7_1_4_6_15"&gt;I2S Loopback Example&lt;/a&gt;.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
