-<!--Sample code:
-<code>
-signed int getTemp(pSCK, pMISO, pCS) {
-    unsigned char buffer[4];
-    buffer[0] = shiftIn(pMISO, pSCK, MSBFIRST);
-    buffer[1] = shiftIn(pMISO, pSCK, MSBFIRST);
-    buffer[2] = shiftIn(pMISO, pSCK, MSBFIRST);
-    buffer[3] = shiftIn(pMISO, pSCK, MSBFIRST);
-    if(buffer[1] & 0x01) // error!
+MAX31855 is somewhat backwards compatible with the MAX6675 however it is 32 bits instead of 16 bits. I shall test to see if this poses a problem.
-    {
-         // short to VCC
+Have to take the "MAX6675_SS" lines from the RAMPS section of pins.h and transpose it to Sanguinololu section.
-         // short to GND
-         // open circuit
+under <code>#define SDSS    31</code> write <code>#define MAX6675_SS    31"</code>.
-    }
-    return 0; // temperature
-}
