Read data from MAX31856 using LINX

Hi everyone,

I am new to labview and arduino.

 

Currently I need to read the temperature from MAX31856.
Now I have use arduino code to test and it work well. The problem is I don't know how to do it by Labview.

Figure below is the program I have written now.
According to the manual of MAX31856, send the register 1(default 03h) could check the type of thermocouple and C(default 00h), D(default 00h), E(default 00h) for temperature.
However, it turns out something weird.
I now for temperature, I need to turn binary into decimal, but from the result of register 1, it does not make sense. So I didn't do that further.

May anyone give me some suggestions how to do it in right way?

Thank you guys in advance.

Hi,

 

Welcome to the Community!

 

Actually, there are a lot of examples and tutorials how to read temperature data with Arduino and LabVIEW.

Check out this video. LabVIEW LINX Arduino Temperature Sensors.

I also created a Converter VI that converts binary into decimal (see attached). Hope you can use the same logic in your project.

I wish I could do more, but for now, I haven't needed hardware to run your code.

 

Have a nice day!
