+** ChibiOS/RT port for ARM-Cortex-M0+ Freedom Board KL25Z. **
+*****************************************************************************
+
+The demo runs on an Freescale Freedom KL25Z board and demonstrates
+the usage of the ADC.
+
+It reads the internal temperature sensor. If the temperature drops
+below 20C (68F) it turns on the blue LED. If the temperature rises
+above 27C (81F) it turns on the red LED. Otherwise the green LED is
+illuminated.
+
+The internal bandgap voltage reference is used to calibrate the
+results returned from the temperature sensor.
