S32K3 + SGTL5000 SAItoI2S Codec

[iverson3ya]

I encountered some issues during testing when sending, as shown in the image below.

I2s_MasterRequest.bufferSize = 260760;//SAI_IP_MAX_NO_OF_FRAMES-1;

If it exceeds SAI_IP_MAX_NO_OF_FRAMES (32767UL), it seems to have this issue.

There appears to be a limitation underneath Sai_Ip_Send, but I checked the demo code, and this restriction 'DevAssert(u32Count < SAI_IP_MAX_NO_OF_FRAMES);' is not there.

So, I commented it out. If this limitation is indeed necessary, how can I play the complete audio file?

void SGTL5000_SAI_test1(void)

{

    volatile boolean bStatus = TRUE;

    /* Create Master/Slave request */

    I2s_MasterRequest.bufferSize = 260760;//SAI_IP_MAX_NO_OF_FRAMES-1;

    I2s_MasterRequest.dataDirection = I2S_SEND_DATA;

    I2s_MasterRequest.pDataBuffer = (I2s_DataType (**))SendData;

    I2s_MasterRequest.autoDisableClock = true;

    I2s_SlaveRequest.bufferSize = BUFF_SIZE - 1U;

    I2s_SlaveRequest.dataDirection = I2S_RECEIVE_DATA;

    I2s_SlaveRequest.pDataBuffer = (I2s_DataType (**))RecvData;

    /* Init buffer data */

    for (int i = 0; i < BUFF_SIZE; i++)

    {

        SendData1[i] = i + 1U;

        RecvBuff1[i] = 0U;

    }

//  pRequest = &I2s_SlaveRequest;

//  Ret = I2s_AsyncTransmit(I2S_SAI_RX, pRequest);

//    if (E_NOT_OK == Ret)

//    {

//        bStatus = FALSE;

//    }

     /* Start sending data */

    pRequest = &I2s_MasterRequest;

    Ret = I2s_AsyncTransmit(I2S_SAI_MASTER, pRequest);

    if (E_NOT_OK == Ret)

    {

        bStatus = FALSE;

    }

   vTaskDelay(10000);

    I2s_GetStatus(I2S_SAI_MASTER, &transferStatus);

    if ((I2S_STATUS_COMPLETED != transferStatus.status) || (0U != transferStatus.byteRemainCount))

    {

        bStatus = FALSE;

    }

}

Additionally, how can I configure SAI0 in the same group to be able to receive as well? Changing the direction using 'I2s_SlaveRequest.dataDirection = I2S_RECEIVE_DATA;' doesn't seem to work.

thanks!

Hello @iverson3ya,

What is the RTD package you are using?

Best regards,

I am using RTD3.0.0, and I have already resolved the thread issue. However, I am now facing a new problem where interrupts often do not trigger.

After I2S reinitialization, it will work properly

void I2s_ReceiverNotification(Sai_Ip_ReportType event)

{

    RxEven = event;

    if( event == SAI_IP_RX_COMPLETE){

        RxFlag = TRUE;

    }

}

    volatile boolean bStatus = TRUE;

    uint32 timeout = 100000000U;

    /* Create Master/Slave request */

    I2s_MasterRequest.bufferSize = BUFF_SIZE - 1U;

    I2s_MasterRequest.dataDirection = I2S_SEND_DATA;

    I2s_MasterRequest.pDataBuffer = (I2s_DataType (**))RecvData;

    // I2s_MasterRequest.autoDisableClock = true;

    I2s_SlaveRequest.bufferSize = BUFF_SIZE - 1U;

    I2s_SlaveRequest.dataDirection = I2S_RECEIVE_DATA;

    I2s_SlaveRequest.pDataBuffer = (I2s_DataType (**))RecvData;

    // I2s_SlaveRequest.autoDisableClock = true;

    /* Init buffer data */

    for (int i = 0; i < BUFF_SIZE; i++)

Hello @iverson3ya,

Could you show me the value of SAI registers when interrupts does not trigger?
