pled and displayed on alternating cycle with the date readings. Therefore, the date and temperature
automatically and continuously alternates on the display. The temperature display can be alternated
between °C and °F by pressing the "+" or "-".
Contrast Adjustments
To adjust the contrast dynamically, the project calls the adjust bias API call provided by the Segment
LCD component. The higher the bias level set in the call to the API the higher the contrast. The API
allows a selection between 0 and 127 with 127 corresponding to the maximum contrast level.
Enter a relative value between 0 and 10; the code maps the contrast setting into bias voltage values
within the range 47 to 67 (3.23V to 3.78V).
LCD Demonstration
To demonstrate all the segments of LCD glass, the project sequentially demonstrates the various
display sections. Refer to

Project Design and Setup
Analog I/O
Thermistor Reference Voltage
The thermistor reference voltage analog connection is configured as an input but is actually an out-
put. The VDAC generates a fixed constant output voltage on the analog port. This reference voltage
is also sent through the AMUX to be sampled by the Delta-Sigma ADC during temperature calcula-
tion periods.
The output is configured for 1-pin width mapping and Hi-Z Analog during Power-On Reset. The port
pin is set for High Impedance Analog. The default Built-In settings are used.
