S32K3 + SGTL5000 SAItoI2S Codec

iverson3ya — Fri, 03 Nov 2023 09:22:19 GMT

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,

Dan

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;

}

void SGTL5000_SAI_PlayRecord(void)

{

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++)

{

//SendData1[i] = i + 1U;

RecvBuff1[i] = 0U;

}

start:

for (int i = 0; i < 10; i++){

pRequest = &I2s_SlaveRequest;

Ret = I2s_AsyncTransmit(I2S_SAI_RX, pRequest);

if (E_NOT_OK == Ret)

{

bStatus = FALSE;

}

while (!RxFlag && timeout){

timeout--;

if(timeout <= 0){

I2s_AbortTransmit(I2S_SAI_RX);

I2s_Init(&I2s_xConfig_VS_0);

printf("RX timeout and init I2S\r\n");

goto start;

}

timeout = 100000000U;

I2s_AbortTransmit(I2S_SAI_RX);

RxFlag = FALSE;

switch(RxEven)

{

case SAI_IP_RX_COMPLETE:

printf("RX SAI_IP_RX_COMPLETE\r\n");

break;

case SAI_IP_SYNC_ERROR:

/* Start sending data */

pRequest = &I2s_MasterRequest;

break;

case SAI_IP_SYNC_ERROR:

printf("TX SAI_IP_SYNC_ERROR\r\n");

break;

default:

break;

}

I2s_GetStatus(I2S_SAI_MASTER, &transferStatus);

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

I2s_GetStatus(I2S_SAI_MASTER, &transferStatus);

}

I2s_AbortTransmit(I2S_SAI_RX);

I2s_AbortTransmit(I2S_SAI_MASTER);

if(gUart_Cmd_ISR_Flag == true){

gUart_Cmd_ISR_Flag = false;

break;

}

Hello @iverson3ya,

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

Best regards,

Dan
