SAI witH CODEC SGTL5000

[DYann.1]

Hello,

I would like to know how to recover acquisition data ​​and save the data to an SD card. I have this configuration

I can compile and communicate with I2C to configure the SGTL5000 CODEC, I enabled DMA too. No errors for this moments.

Thank you for your helps.

I have this code below but I don't know how does it work ?

 HAL_SAI_RegisterCallback(&hsai_BlockB1, HAL_SAI_TX_HALFCOMPLETE_CB_ID, HAL_SAI_TxHalfCpltCallback);
 HAL_SAI_RegisterCallback(&hsai_BlockB1, HAL_SAI_TX_COMPLETE_CB_ID, HAL_SAI_TxCpltCallback);
 fresult= HAL_SAI_Init(&hsai_BlockB1);
 if (fresult != HAL_OK)
	{
 	return HAL_ERROR;
	}
 fresult = HAL_SAI_Transmit_DMA(&hsai_BlockB1, (uint8_t *)playbuf , (sizeof(playbuf))/4);

Do you have a idea how to get the acquisition values ?
