  Initial revision.


II - Application description
============================

 This application reads the current temperature on a MAXIM MAX 6662 device
(temperature sensor), plugged on the SPI bus.

 First it uses the AT+CGMR command to get the product version, to automatically
set SPI parameters according to the product (SPI chip select, and SPI clock
speed).

 Then it opens the SPI bus and start a 1s cyclic timer.
 
 Each time the timer occurs, the current temperature is read, and if it is
different from the previous read value, it is displayed in a debug trace, and
in a "+TEMP: ..." unsolicited response on the serial link.
