Good day, I'm quite a beginner user of LabVIEW and wish to request some help from this forum regarding SPI communication. I have a K-type thermocouple connected to a MAX6675 (cold junction compensated digital converter). It requires SPI communication and I connected the pins accordingly. MAX6675 Arduino Uno ----------- -------------- VCC 5V pin GND GND pin SCK digital pin 13 SO digital pin 12 CS digital pin 10 1. I've loaded the LINX firmware into Arduino Uno. 2. Built the following block diagram. 3. Set the SPI configuration as followed. When I run the program in LabVIEW, nothing shows up in the "Read data" array. Can anyone shed some light on what's wrong with my design?? Thank you.
