CCS/MSP430F6438: msp430f6438

Part Number: MSP430F6438

Tool/software: Code Composer Studio

this is my code

#include <msp430.h>
#include<math.h>
#include<stdio.h>

//sample RTD code for wheatstone Bridge as per schematic A0




#define GAIN 31.14 //gain of opamp
#define VSOURCE 3.3 //vsource
#define R0 100 //resistance of rtd at 0
#define Temp_Coeff 0.00385 //tempreture coeff is for the platinum

void init_adc() //no interrupts
{

ADC12CTL0 = ADC12SHT02|ADC12ON; //1.selects the 16 cycle per sample 2.adc on|ADC12MSC
ADC12CTL1 = ADC12SHP|ADC12CONSEQ_2; //1.signal source from the sampling timer 3.repeate single channel
ADC12CTL2 = ADC12TCOFF|ADC12RES_2; //1.make internal temp senser off 2.select 12 bit resolution
ADC12MCTL0 =ADC12SREF_2 ; //1.To make External Ref Enable for the channel A0


}


int main(void)
{
WDTCTL = WDTPW | WDTHOLD; // stop watchdog timer


P6SEL |= BIT0;


init_adc();//initlialize the ADC


float Vout,Rrtd,X,Temp,LSB;

//while(1)
//{

ADC12CTL0 |=ADC12ENC|ADC12SC;//enable the adc and sampling and conversion start

while (!(ADC12IFG & BIT0));

LSB=33/40950;


Vout =ADC12MEM0;
Vout = Vout*LSB/GAIN;
Vout = Vout*1000;

printf("vout %f\n",Vout);

X=((Vout/VSOURCE)-0.5);//X=(Vout/Vsource-1/2)
printf("X== %f\n",X);

Rrtd= ((X*R0/(1-X)));
printf("value of RTD %f\n",Rrtd);

Temp=((Rrtd-R0)/(R0*Temp_Coeff));


//}


printf("Tempreture of is -------> %f\n",Temp);

return 0;
}

the float value does not print on to the console

the output i get on the console as

Vout 

X==

Rrtd

Temp 

float value not get printed help with this..

thank you.
