RTOS/AWR1642: Read temperature from the temp sensor in awr1642

Cassie

Part Number: AWR1642

Tool/software: TI-RTOS

Hello,

experts, I'm working on getting the chip temperaturte when awr1642 is working. I know in the demo, there is rlRfGetTemperatureReport() API which we can call to make it. And i add this API into the sdk_01_01_00_02 as follow:

static int GetTemperature(void)
{
   rlRfTempData_t   TempData;
   rlRfGetTemperatureReport(RL_DEVICE_MAP_INTERNAL_DSS_MSS, &TempData);
   UART_writePolling (gMmwMssMCB.loggingUartHandle, (uint8_t*)&TempData,sizeof(TempData));

   return 0;
}

static void GetTemperatureTask(UArg arg0, UArg arg1)
{
   while(1)
   {
       if(GetTemperature() < 0)
       {
       //   DBG("Failed");
           System_printf("Error in getting temperature!");
       }
       Task_sleep(1000);
   }
}

And then I create a task in the MmwDemo_mssInitTask():

    Task_Params_init(&taskParams);
    taskParams.priority = 7;
    taskParams.stackSize = 1024;
    Task_create(GetTemperatureTask, &taskParams, NULL);

But the data received is all 'FF',as show in the screenshot.

Could you offer some help?

Thanks a lot,

Cassie

Hi Cassie,

Could you make sure that getTemprature API returns success? And try to print individual parameters of tempData structure as suggested in following code snippet.

    rlRfTempData_t tempData = {0};
    while(1)
    {
        errCode = rlRfGetTemperatureReport(RL_DEVICE_MAP_INTERNAL_BSS, &tempData);
        if(errCode < 0)
        {
            CLI_write("GetTemp API failed \n");
        }
        else
        {
            CLI_write("Temperature: %d, %d, %d, %d, %d, %d, %d, %d \n", tempData.tmpRx0Sens, tempData.tmpRx1Sens,
                                                                        tempData.tmpRx2Sens, tempData.tmpRx3Sens, 
                                                                        tempData.tmpTx0Sens, tempData.tmpTx1Sens,
                                                                        tempData.tmpPmSens, tempData.tmpDig0Sens);
        }
        
        Task_sleep(1000);
    }

Hi Jitendra,
Thank you for your answer.I've tried as you suggested and I got the API failed.The errorCode is -2(RL_RET_CODE_INVALID_INPUT). are the device map RL_DEVICE_MAP_INTERNAL_BSS and RL_DEVICE_MAP_INTERNAL_DSS_MSS valid in Awr1642 Boost1.0? Or is there anything needed to be initialized?

Best wishes,
Cassie.

Hi Cassie,

You are getting negative return value as you may not have intialized the mmwave module in the application.

Here is the code reference based on mmw demo (mss_main.c) which you can use in your application.

Event_Handle eventHandleNotify_0;

void MmwDemo_mssMmwaveStartCallbackFxn(MMWave_CalibrationCfg* ptrCalibrationCfg)
{
    /* Post an event to main data path task. 
       This function in only called when mmwave_start() is called on DSS */
    gMmwMssMCB.stats.datapathStartEvt ++;

    /* Post event to start is done */
    Event_post(gMmwMssMCB.eventHandleNotify, MMWDEMO_DSS_START_COMPLETED_EVT);

    //TODO  along with this point, add next line of code in the same file wherever 'MMWDEMO_DSS_START_COMPLETED_EVT' event is getting posted (Event_post).
    Event_post(eventHandleNotify_0, MMWDEMO_DSS_START_COMPLETED_EVT);
}


void Mmwdemo_mssInitTask(...)
{
   .....
   .....
    eventHandleNotify_0 = Event_create(NULL, &eb);
    if (eventHandleNotify_0 == NULL) 
    {
        MmwDemo_mssAssert(0);
        return ;
    }

    .....
    .....
    
    MmwDemo_CLIInit();

    /*****************************************************************************
     * Benchmarking Count init
     *****************************************************************************/
    /* Configure banchmark counter */
    Pmu_configureCounter(0, 0x11, FALSE);
    Pmu_startCounter(0);
   
    rlRfTempData_t tempData = {0};
    
    /* Pend on the START NOTIFY event */
    Event_pend(eventHandleNotify_0, 
                          Event_Id_NONE, 
                          MMWDEMO_DSS_START_COMPLETED_EVT,
                          BIOS_WAIT_FOREVER);
                          
    while(1)
    {
        errCode = rlRfGetTemperatureReport(RL_DEVICE_MAP_INTERNAL_BSS, &tempData);
        if(errCode < 0)
        {
            CLI_write("GetTemp API failed \n");
        }
        else
        {
            CLI_write("Temperature: %d, %d, %d, %d, %d, %d, %d, %d \n", tempData.tmpRx0Sens, tempData.tmpRx1Sens,
                                                                        tempData.tmpRx2Sens, tempData.tmpRx3Sens, 
                                                                        tempData.tmpTx0Sens, tempData.tmpTx1Sens,
                                                                        tempData.tmpPmSens, tempData.tmpDig0Sens);
        }
        
        Task_sleep(1000);
    }    

}

Hope this will help you to resolve this issue.

Jitendra
