AutoLight V2.2

HTC Topaz (Diamond 2) auto adjust backlight function is a good idea with a not very good implementation. It must be said to HTC excuse that the light sensor is very noisy, especially at low light conditions.
Some alternatives do exist but are not very good or are Compact Framework application (not a very good idea for background application).
AutoLight is supposed to be a better implementation for the auto adjust backlight function.

Requirements and compatibility

AutoLight was developed for HTC Topaz (Diamond 2) with WM6.1 and it critically depends on HTCSensorSDK.dll, HTCUtil.dll and on a 10 levels backlight starting from value 1.
It has been reported to work on Rhodium (Touch Pro 2) and it might works on some other HTC phone but the test is up to you. I do not think it can work on non-HTC phones.
AutoLight is a native application with a very low memory usage. On the other hand the Configurator requires Compact Framework 2 but it should be closed after the use.
The Configurator is designed for WVGA screens.

Install

Run AutoLight.cab and install in main memory (not in storage card), run AutoLight.Config.cab and install where you like, then softreset (this should also disable the native auto adjust backlight function, check for that in the Control Panel Power applet).

Uninstall

To uninstall AutoLight use the Configurator to stop it, then use Remove Programs in Settings.
AutoLight can be also be stopped running the AutoLightStop utility.
To uninstall AutoLight Configurator use Remove Programs in Settings.

Configurator

AutoLight working depends on parameters it gets from registry. For details on parameters see ReadMe.txt, AutoLight.reg.txt and AutoLigth.reg
The Configurator gives a more user friendly access to these parameters. Nevertheless, the configuration process is quite complex and should be done after thoroughly reading AutoLight.reg.txt.
The second tab of the Configurator contains a graphical representation of the calibration table used to convert light sensor to backlight values. Note that:
- the horizontal scale is not linear but goes according to square root of the light sensor value;
- the horizontal red segments represent the ranges of light sensor values assigned to every backlight level;
- the horizontal red segment whose backlight level is selected (with the control on top of the second tab) turns blue;
- the small rectangles connecting the segments are the hysteresis;
- the vertical blue line is the current light sensor value (only available when AutoLight is running);
- the horizontal blue line is the current backlight level (only available when AutoLight is running).

User offset change

If you are not satisfied with the backlight level as computed by AutoLight you can rapidly adjusting it by going to the Control Panel Power applet and changing it (feature is disabled by default, details inside ReadMe.txt).

Increment/decrement backlight command line utility

Using ChangeLight.exe and a hardware button mapper you can change backlight without opening the Control Panel (details inside ReadMe.txt).
