| :relevant-api: i2s_interface |
| |
| Process an audio stream to codec. |
| |
| Overview |
| ******** |
| |
| This sample demonstrates how to use an I2S driver in a simple processing of |
| an audio stream. It configures and starts from memory buffer or from DMIC to |
| record i2s data and send to codec with DMA. |
| |
| Requirements |
| ************ |
