#define FOO BAR, and then do
char something = "FOOBAR", will that string compile as BARBAR?
Initially, I had planned to use GPIO16 for the DS18B20 one-wire interface. That would have physically routed all the pins used for the sensors on one side of the ESP8266. This would not work, however, since GPIO16 can be used as an input or an output, but does not have the INPUT PULLUP, and OUTPUT_OPEN_DRAIN capability of the other GPIO pins. That feature is needed for the one-wire interface.
