Hey sorry for the delay in the kode and translation.
Has been a lot of work for a while now, but now I'll grab this.
It is Temp1 and Temp2 value I want into Labveiw.
#include <stdio.h>

Timer1.initialize(1000000); // initialize timer1, and set a 1 second period
oldmilli = millis();
}

{
double res1,res2,res3; // denne kan bare stå sånt i tilfelle du vil ha 3 pt100 senere

pumpetemp = Temp1;

/* timer loop sees that it will only be sent information on a certain interval */
milli = millis();
if (milli > oldmilli + 50) // 500 is 1/2 sec delay between data packets

}
if(startindex!=-1) {
nOff=width[startindex]+width[startindex+1];
nAB=width[startindex+2];
nCD=width[startindex+3];
nBC=width[startindex+4];

Sorry but the code is not integrated with Lifa right now
