| |
| Status: |
| version 1.0.0 |
| |
| Purpose: |
| This Library is used to decode and reconstruct the audio signal |
| produced by ST MEMS microphone (MP45Dxxx, MP34Dxxx). |
| |
| Description: |
| This library, written by STMicroelectronics, is used to convert an audio |
| stream from PDM format to PCM format through a signal filtering and |
| decimation. |
| |
| Library APIs: |
| - Open_PDM_Filter_Init() /* Init the OpenPDM2PCM library */ |
| - Open_PDM_Filter_64() /* Filter and decimate stream by 64 */ |
| - Open_PDM_Filter_128() /* Filter and decimate stream by 128 */ |
| |
| |
| Dependencies: |
| This library depends by Zephyr mpxxdtyy driver and is linked statically. |
| This library will be used by a standard Zephyr microphone driver |
| (./drivers/audio/). |
