Hello World! 🙂
this is Nino. First of all thanks for accepting me in this community!
I am trying to read the temperature of a K-thermocouple interfaced with a MAX6675 SPI, using Arduino and Labview.
However, I could not find any information / tutorial on how to make this project working and I have no Idea on how to do this.
I am using:
My MAX6675 is connected with the following PINs
Could you, please, post a working VI for this project or Post some instructions I can refer to?
Thanks in advance for reading my post and for your kindness
Unfortunatelly i do not have this solution made yet.
However there is an example of linx communication with arduino usint the PmodTC1 in the examples folder called LINX -PmodTC1.vi
the PmodTC1 also uses maximintegrated IC, but the MAX31855 instead of MAX6675.
I believe that with some of non work arounds you may be able to change that code to fit your needs.
Thanks a lot, that was very helpful ! 🙂
Something I did not get is this:
To use the MAX31855 with PmodTC1 VI it is still necessary to modify the LIFA BAse?
Does it work just with the original LINX LIFA?
I tried out yesterday with another SPI chip, just changed the subvi parameters to set clock mode and channel, worked ok.
now i believe that you don't need LIFA anymore, since it has been substituted by LINX officially.
Could you send me your vi and explain which parameters should be changed, please? I'd just like to try ho it works..
Thanks for your time, I appreciate it very much
I was also searching for the same. If you found the answer, please share it with me also.
In the meantime what I did to make it work is, I uploaded the Arduino sketch for reading the temperature using the Arduino app and serial printed the temperature value. After that, I acquired the value in LabVIEW using a serial read from Arduino. And it worked well.
Just let me know if you require the Arduino sketch and LabVIEW vi.
actually i modify the pmod TC1.vi and can read the temperature of max 6675 but i have problem because i think i have a error at the temperature convert
now i try to check the temperature with an other instrument to verify the data
actualy i am working on this vi
i have to check the temperature to verify that is correct but i think is ok
if anybody see a error please tell me
