00008 NOTES
00009 
00010 no point in specifying a port- all the different temp sensors we have must be on a particular port. The MAX6675 must be on the SPI, and the thermistor and AD595 must be on an analog port.
00011 
00012 we still need to specify which analog pins we use in machine.h for the analog sensors however, otherwise the analog subsystem won't read them.
