* THERMISTOR LOGGING (aka Temperature Log)
|
|
*
|
|
* This watch face automatically logs the temperature once an hour, and
|
|
* maintains a 36-hour log of readings. This watch face is admittedly rather
|
|
* complex, and bears some explanation.
|
|
*
|
|
* The main display shows the letters “TL” in the top left, indicating the
|
|
* name of the watch face. At the top right, it displays the index of the
|
|
* reading; 0 represents the most recent reading taken, 1 represents one
|
|
* hour earlier, etc. The bottom line in this mode displays the logged
|
|
* temperature.
|
|
*
|
|
* A short press of the “Alarm” button advances to the next oldest reading;
|
|
* you will see the number at the top right advance from 0 to 1 to 2, all
|
|
* the way to 35, the oldest reading available.
|
|
*
|
|
* A short press of the “Light” button will briefly display the timestamp
|
|
* of the reading. The letters at the top left will display the word “At”,
|
|
* and the main line will display the timestamp of the currently displayed
|
|
* data point. The number in the top right will display the day of the month
|
|
* for the given data point; for example, you can read “At 22 3:00 PM” as
|
|
* ”At 3:00 PM on the 22nd”.
|
|
*
|
|
* If you need to illuminate the LED to read the data point, long press the
|
|
* Light button and release it.
