Compiler/TMP102: Using TMP102 with MSP430fr6989

I apologize the not being too clear.

In the power up process, I’m initializing the sensor to disabling it. This is before my first attempt to read temperature sensor. I repeatedly send word to configuration register and read back; and sensor returns with OS (one-shot) bit set to HIGH. According to manual, I need to disable sensor before I set to OS to read temperature if I do not want sensor to in continual read mode. You’re welcome to view my codes sent to you offline for your review. I can’t copy and paste my code here due to size of coding and that I have several library of my own that is crazy to tying to copy and paste in the text box.

this is what I do in the main 

void main(void)

{

   Init_GPIO();

   Init_Sys_Clock();

       Init_Timer_A1(); 

       #if defined(UART_A0_SERIAL_COMMUNICATION) || defined(UART_A1_SERIAL_COMMUNICATION)

              UART_Init();

              // test UART communication

              UART_transmitString(szTitleText);

              __delay_cycles(5000000);

              //delay_mSec(5000);

              // clear screen

              UART_transmitString("\ec");

       #endif

       #ifdef BUILTIN_LCD_DISPLAY

              LCD_Init();

       #endif

       #ifdef I2C_SENSOR_ATTACHED

              Init_TMP102();

       #endif

   while(1)

   {

      // set to LPM3 mode, enable interrupt

       __bis_SR_register(LPM3_bits + GIE);

       if (temperature_Read_OneShot == true)

       {

             temperature_Read_OneShot = false;

             set_TMP102_OneShot_Read();

             __delay_cycles(50000);

             displayTemperature();

       }

   }

}

and in separate TMP102 class library.
