Features of lighting-capable Logitech Gaming mice and keyboards

Different devices have different capabilities. They range from full single-key RGB support to single color only. Details for supported devices are found further below in “Features of lighting-capable Logitech Gaming mice and keyboards”. The SDK has a single function to set the backlighting color and takes values for R(ed), G(reen), B(lue). The way it deals with single color devices is to take whichever of the R, G, and B values is the highest and apply it. This is important to remember, because if for example rotating through colors, the game should make sure to alternate the maximum numbers as it rotates so that the effect on a single color device would be noticeable too.

This crate will try to locate and load LogitechLed.dll at runtime. We start by looking up the CLSID in the Windows registry, if it’s found we load the library with a call to LoadLibrary() with the full path. If it fails we call LoadLibrary() with just the DLL name. This will search your PATH for the library.

The SDK allows only one client to control backlighting at any given time. In case two applications try to initialize the SDK, the latest one will take over control.
