问题
I'm trying to get Logitech's own LED SDK working with my G502, but I can't. I'm using SDK version 8.82.7, which is, as of now, the most recent version. I also couldn't find anything on SO or the rest of the internet, so I'm asking here.
Here's my LogitechGSDK.cs:

My color changing code basically amounts to
LogitechGSDK.LogiLedInit();
LogitechGSDK.LogiLedSetTargetDevice(LogitechGSDK.LOGI_DEVICETYPE_ALL);
LogitechGSDK.LogiLedSetLighting(255, 127, 0);
which should set my mouse's LEDs to a nice orange, but in reality does nothing. It's worth noting that Logitech's own samples, which are included in the SDK .zip, do not work. I can set the LED color with Logitech's Gaming Software, but that's not what I want.
Is Logitech's SDK broken? If not, what can I do to get it working?
Edit: I should probably mention that I do own the RGB version of the G502.
回答1:
In your code the Arguments of LogitechGSDK.LogiLedSetLighting(255, 127, 0);
are incorrect as they exceed the value limitation.
They are supposed to be percentages not RGB values.
Enter a number between 0 and 100 for it to work.
Also replace your code:
LogitechGSDK.LogiLedSetTargetDevice(LogitechGSDK.LOGI_DEVICETYPE_ALL);
With:
LogitechGSDK.LogiLedSetTargetDevice(LogitechGSDK.LOGI_DEVICETYPE_RGB);
Or remove it all together.
Here is an example of orange:
LogitechGSDK.LogiLedSetLighting(100, 30, 0);
Remember to give enough time for the code to initialize.
