CC2564MODA: Metallic troubles in the audio files shared with my phone and problems with pairing

Nicolas,

This could be due to improper I2S line configuration.

Can you share which I2S/PCM parameters are you using on both CC2564MODA and TLV320ADC3101 side?

Best regards,
Vihang

Hello Vihang,

About the parameters, they are configured as follow:


For TLV320ADC3101:



static void ConfigureCodecTLV(void)
{
/* Start of TLV320ADC3101 Interfaces Setup */
/* AUD_nRESET, I2C */
// TLV320ADC3101 AUD_nRESET - P1.7
P1DIR |= BIT7; // P1.7 = Output
P1OUT &= ~BIT7; // P1.7 = Low (TLV320ADC3101 OFF)
// TLV320ADC3101 I2C IOs - MSP_SDA P3.0, MSP_SCL P3.1
P3SEL |= (BIT0 + BIT1); // P3.0,1 = USCI_B0 Mode, SDA and SCL
// TLV320ADC3101 I2C Module - USCI_B0
UCB0CTL1 |= UCSWRST; // Hold module in reset state
UCB0CTL0 = UCMST + UCMODE_3 + UCSYNC; // I2C Master, 7-bit Address, Synchronous Mode
UCB0CTL1 = UCSSEL_2 + UCSWRST; // SMCLK Source, keep SW reset
UCB0BR0 = 19; // fSCL = SMCLK/20 = 400kHz
UCB0BR1 = 0; // fSCL = 8MHz/20 = 400kHz
UCB0I2CSA = 0x18; // Slave Address is 018 -> 0011 000
UCB0CTL1 &= ~UCSWRST; // Enable module
UCB0IE |= UCTXIE; // Enable USCI_B0 TX interrupt
UCB0IE |= UCRXIE; // Enable USCI_B0 RX interrupt
/* End of TLV320ADC3101 Interfaces Setup */

// Turn TLV320ADC3101 device On
__delay_cycles(800000); // Wait 100ms before turning TLV320ADC3101
P1OUT |= BIT7; // P1.7 = High (TAS2505 ON)
}






For Bluetooth, this is my main thread (HFP communication):

static void MainThread(void)
{
int Result;
BTPS_Initialization_t BTPS_Initialization;
HCI_DriverInformation_t HCI_DriverInformation;
HCI_HCILLConfiguration_t HCILLConfig;
HCI_Driver_Reconfigure_Data_t DriverReconfigureData;

/* Flag that sleep is not currently enabled. */
SleepEnabled = FALSE;

/* Configure the UART Parameters. */
HCI_DRIVER_SET_COMM_INFORMATION(&HCI_DriverInformation, 1, 115200, cpHCILL_RTS_CTS);
HCI_DriverInformation.DriverInformation.COMMDriverInformation.InitializationDelay = 100;

/* Set up the application callbacks. */
BTPS_Initialization.GetTickCountCallback = GetTickCallback;
BTPS_Initialization.MessageOutputCallback = DisplayCallback;

/* Initialize the application. */
if((Result = InitializeApplication(&HCI_DriverInformation, &BTPS_Initialization)) > 0)
{
/* Save the Bluetooth Stack ID. */
BluetoothStackID = (unsigned int)Result;

/* Register a sleep mode callback if we are using HCILL Mode. */
if((HCI_DriverInformation.DriverInformation.COMMDriverInformation.Protocol == cpHCILL) || (HCI_DriverInformation.DriverInformation.COMMDriverInformation.Protocol == cpHCILL_RTS_CTS))
{
HCILLConfig.SleepCallbackFunction = HCI_Sleep_Callback;
HCILLConfig.SleepCallbackParameter = 0;
DriverReconfigureData.ReconfigureCommand = HCI_COMM_DRIVER_RECONFIGURE_DATA_COMMAND_CHANGE_HCILL_PARAMETERS;
DriverReconfigureData.ReconfigureData = (void *)&HCILLConfig;

/* Register the sleep mode callback. Note that if this */
/* function returns greater than 0 then sleep is currently */
/* enabled. */
Result = HCI_Reconfigure_Driver(BluetoothStackID, FALSE, &DriverReconfigureData);
if(Result > 0)
{
/* Flag that sleep mode is enabled. */
SleepEnabled = TRUE;
}
}

HAL_SetLedState(BT_WAIT_t);

/* Add the idle function (which determines if LPM3 may be entered)*/
/* to the scheduler. */
if(BTPS_AddFunctionToScheduler(IdleFunction, NULL, 0))
{
BTPS_AddFunctionToScheduler(StateFunction, NULL, 100);
/* Loop forever and execute the scheduler. */
while(1)
{
BTPS_ExecuteScheduler();

}
}
}
}


Do you need anything else? (If not published, I can send to you my whle project if needed)

Nicolas,

The code above does not cover the call to HCI_VS_Codec_Config command, which configures the I2S interface of the CC2564.

Moreover, the ConfigureCodecTLV() function above is just configuring the I2C interface of the MSP430 to control the TLV320ADC3101. What I2S parameters does the TLV320ADC3101 use?

I sent you connection request on e2e portal. You can share your project privately from there.

Moreover, can you please do a PCM loopback test to check if the noise still exists?

Best regards,
Vihang

Hello Vihang,

I want to send you my whole project, but did not find the way to "share my project privately". I can't see what is you request on E2E portal. Could you please tell me how to do precisely?

Thank you,

With Regards,

Nicolas

Dear Vihang, 

Thank you for your proposal,

I will test and see if the behaviour is now improved, as done as it happened "some times" only. 

With Regards,
