Hello,
I should use Labview to measure temperature via a four wire Pt100, with a MAX31865 sensor that use an SPI intarface.
Unfortunately Labview does not have an example VI for this sensor and I have not found anything working online.
I know a little about Labview but nothing about Arduino
I have read everything I found on the SPI and Arduino but I can't solve the problem.
Using Arduino IDE (with the attached scetch) the system works, so the hardware is OK.
On Labview I am using LINX, (loading LINX firmware for Arduino Uno) but I can only read constant values that vary according to the values of the bytes I write in the register.
Probably I make mistakes in writing the configuration on the Arduino register, but given my experience it could be anything else! From what I understand, reading the sensor data sheet, the library and the Arduino schetch and looking online, in registers from 7 to 0 Byte 10100011 must be written.
I've tried all the ways but can't get reasonable measurements.
Can anyone give me some tips?
I attach the VI labview
Thank you very much
