[Shimmer-users] Add in the internal temperature

[jackey gong]

Dear all,

I am trying to add the value from the internal temperature sensor of MSP430
in Shimmer2R. So, I change some values in the BTstream firmware, in the
shimmerAnalogSetupP.nc, I change the value of

  command void shimmerAnalogSetup.addGyroInputs() {
   // uint8_t new_chans[] = { 1, 6, 2 };    // x, y, z
   uint8_t new_chans[] = { 1, 10, 2 };    // x, internal temp, z
    addNewChannels(new_chans, 5);

    initADC12MEMCTLx();

    TOSH_MAKE_ADC_1_INPUT();
    TOSH_SEL_ADC_1_MODFUNC();

 //   TOSH_MAKE_ADC_6_INPUT();
 //   TOSH_SEL_ADC_6_MODFUNC();

    TOSH_MAKE_ADC_2_INPUT();
    TOSH_SEL_ADC_2_MODFUNC();
  }

Since the temperature sensor do not need configure any channel of the ADC,
so I delete the PORT configuration for ADC.

But I did not get the right temperature value, it seems like some noise
from other channels. Especially when I rotate the Gyro module, the
temperature value also have some variations on it.

Would you like to help me out?

Thanks,
Jackey
