Dear @SMitt ,
In order to activate I2S in master mode with DMA you need to:
- Activate I2S3 and choose between Half-duplex/Full-duplex under multimedia.
- Add DMA under System core and choose I2S_EXT_RX.
After that you will have i2s master configured with DMA.
Hope that this solve your issue,
Kind regards,
Houssem
