4.1.3 Demo 3 - Voltage trimming and LED level indication
1 Initialises the pins as follows:
2 Reads the A/D converter data register, and turns on a LED according to the Voltage value
Adjusting the voltage trimmer (marked 6 on the Starter Kit board diagram on page 11) turns on
the appropriate LED.
4.1.4 Demo 4 - Temperature Control

ceeds the value that was stored at reset, a LED is turned on indicating the difference be-
tween the two values. The higher the difference is between the stored value and the read
value, the higher LED number is turned on (roughly in steps of LD( n +1) for each additional
degree difference).
