Max6675 for k-type thermocouple temperature reading using arduino and labview

Hi; I am trying to measure temperature using arduino mega +labview 2013 +k-type thermocouple+max6675.

I am using LIFA interface.

The circuit digram  and labview file is attatched

I am stuck on spi read/write palet. How to read 12 bit max reading and convert it to temperature in degree celcious?

Max6675 produce output in 12 bit, and measure 0-1023 centegrade. According to this the

Temperature (C0)= max6675 output (12bit)* 0.25. how to set this formula in labview?

Pin connections are

Max6675 breakout board pins

Arduino Maega Pins

GND

VCC

5 VOLTS

You need to convert the string you get into an integer (i.e. Scan From String) and then you can apply the scaling.

If you continue to have problems, provide the exact string that you get back.

Sorry, I misunderstood you. I thought you had code that already read the arduino. I don't have one.

Hola pedro_16,

 

Dado que éste foro tiene ya un par de años, te recomiendo colocar tu pregunta como un tema nuevo en los foros dedicados al uso de Arduino en LabVIEW: LabVIEW Interface for Arduino Discussions

 

Si prefieres soporte en español, puedes preguntar en la comunidad hispanohablante: Discusiones sobre Productos NI

 

Mucho éxito en tu proyecto! Un saludo,
