/*
|
|
* Aperture-priority Light Meter Face
|
|
*
|
|
* Tested with the "Q3Q-SWAB-A1-00 Temperature + Test Points + OPT3001" flexboard.
|
|
* This flexboard could use a revision:
|
|
*
|
|
* - The thermistor components should be moved west a mm or flipped to the backside
|
|
* to avoid stressing the flexboard against the processor so much.
|
|
* - The 'no connect' pad falls off easily.
|
|
*
|
|
* Controls:
|
|
*
|
|
* - Trigger a measurement by long-pressing Alarm.
|
|
* Sensor integration is happening when the Signal indicator is on.
|
|
*
|
|
* - ISO setting can be cycled by long-pressing Light.
|
|
* During integration the current ISO setting will be displayed.
|
|
*
|
|
* - EV measurement in the top right: "LAP" indicates "half stop".
|
|
* So "LAP -1" means EV = -1.5. Likewise "LAP 13" means EV = +13.5
|
|
*
|
|
* - Aperture in the bottom right: the last 3 main digits are the f-stop.
|
|
* Adjust this number in half-stop increments using Alarm = +1/2 and Light = -1/2.
|
|
*
|
|
* - Best shutter speed in the bottom left: the first 3 digits are the shutter speed.
|
|
* Some special chars are needed here: "-" = seconds, "h" = extra half second, "K" = thousands.
|
|
* "HI" or "LO" if there's no shutter in the dictionary within 0.5 stops of correct exposure.
|
|
*
|
|
* - Mode long-press changes the main digits to show raw sensor lux measurements.
