Map 3000-6500 to 0-255

[HitFrostbite]

Hi,
I've created a skin to control the brightness and color temperature of my smart bulb via command line.
But the problem is that the values to control the color temperature range from 3000-6500,
I have set a scroll function using clamp to achieve that:

Code: Select all

MouseScrollDownAction=[!SetVariable Brightness (Clamp(#CT#-#CTIncrement#,3500,6500))][!CommandMeasure SetCT "Run"] [!Update]
MouseScrollUpAction=[!SetVariable Brightness (Clamp(#CT#+#CTIncrement#,3500,6500))][!CommandMeasure SetCT "Run"] [!Update]

But the x position of the slider on my skin needs to move from 0-255.

Is there any way to map the 3000-6500 to 0-255?

Thanks

Divide your range by 256 to find a divisor of the brightness variable to use in your formula.

If your range is 3000 (according to your scroll formula: 6500-3500), then you can set the X value to X=(floor(#Brightness#/11.71875))

If you want the range to be 3500 (6500-3000), then set X=(floor(#Brightness#/13.671875))

Add DynamicVariables=1 to the meter to use the current value of #Brightness#.

Thanks I'll try it out.

It worked!
Thanks a lot!
