multiple max6675 thermocouples

[fatmat]

Hello

I'm having problems trying to creating a vi for 3 max6675 thermocouples. I have created a vi for one without a problem. This is my sketch, which works on the arduino serial monitor.

#include "max6675.h"
int ktcSO = 8;
int ktcCS = 9;
int ktcCS2 = 11;
int ktcCS3 = 12;
int ktcCLK = 10;
MAX6675 ktc(ktcCLK, ktcCS, ktcSO);
MAX6675 ktc2(ktcCLK, ktcCS2, ktcSO);
MAX6675 ktc3(ktcCLK, ktcCS3, ktcSO);

void setup() {
Serial.begin(9600);
// give the MAX a little time to settle
delay(500);
}
void loop() {
// basic readout test
Serial.print("First = ");
Serial.println(ktc.readCelsius());
Serial.print("Second = ");
Serial.println(ktc2.readCelsius());
Serial.print("Third = ");
Serial.println(ktc3.readCelsius());
delay(500);
}

is this possible ?

Thanks

Does anyone know if this is possible? Is there way that labview can read the thermocouples individually ? If not I'll try something different.

Not possible,

You should add digitalwrite("anotherCS pins",HIGH);
