I am trying to read a MAX31855 SPI thermocouple. There is no input only an output I tried using read write but it never returned a result. I noticed that in SPISendRecive.vi that it used SPI Data to determine how many "Bytes to Read" from SendRevive.vi and pulled the wire and added a varible equal to the word size. I now get an output but the data isn't what I expected. anyone have some advice?This is what I did to make it read without having to send data.this is the board I designed and am testing with.

With this setup it is doing everything even the errors
