SPI Read/Write using LabVIEW for MAX31865

[inder_chawla]

Hi!

We need to connect MAX31865 with LabVIEW. To do so, we have to provide some kind of address register and configuration register through digital input SDI. Can anyone please tell me how to do it? Any help would be appreciated.

You need to get LabVIEW to communicate using the SPI Protocol.  Please see Understanding the SPI Bus with NI LabVIEW for some ideas.  You will probably need some additional hardware ...

you need additional hw to implement that. NI has an SPI module, you can also use arduino/Teensy type of microcontroller LabVIEW MakerHub • View topic - Teensy SPI with LabVIEW

I am connecting MAX31865 to BNC2110 and the same is read using LabVIEW DAQ PCIe6323. The problem is to start the data read from MAX31865, I need to send a signal (address register) from LabVIEW to MAX31865. I am not really sure how to do so. Can you guide me on how to give the digital signal (address register) to the SDI Line of MAX31865?

I have not done it myself, check this post to see if your board would be able to do SPI
