firts you have to load the linxs firmware on to arduino nano

late you have to conect the arduino with max6675 remember

arduino digital 13----sck -----to sck of max6675

arduino digital  12--- miso ---to miso of max 6675

arduino digital  3---- cs ----- to cs of max6675 (*)

you can use pin 3, 5,6,9,10,11  (PWM pins)

use my VI and  slect the COM of comunication betwen arduino and pc

select the SPI chanel default 0

select CS is the number of you use to conect arduino wtih max6675

i dont use arduino nano but i think thats the same
