title: Multiple thermocouples on raspberry pi
body: <p>I am pretty new to the GPIO part of the raspberry Pi.  When I need pins I normally just use Arduino.  However I would really like this project to be consolidated to one platform if possible, I would like to do it all on the PI.  </p>
  
  <p>So I have three (3) <a href="https://datasheets.maximintegrated.com/en/ds/MAX31855.pdf" rel="noreferrer">MAX31855</a> boards and type K Thermocouples.  I just don't know where to go with hooking up the other two.  I don't know if I can just use any other pins (besides power and ground pins) for the MISO, CSO, and SCLK pins.  This may sound like a rookie question but like I said I'm used to using arduino for this stuff.  Any input is appreciated.  Thanks in advance.</p>
  
  <p>I'm using code from <a href="https://github.com/Tuckie/max31855" rel="noreferrer">https://github.com/Tuckie/max31855</a></p>
  
  <pre><code>from max31855 import MAX31855, MAX31855Error
  
  cs_pin=24
  clock_pin=23
  data_pin=22
  unit="f"
  thermocouple1=MAX31855(cs_pin, clock_pin, data_pin, units)
  print(thermocouple.get())
  thermocouple.cleanup()
  </code></pre>
