Unable to set colors for some keys

[antonpup]

I am experiencing an issue where I cannot set color for some keys on a Corsair Strafe RGB and I cannot change the color of the DPI indicator on Corsair Sabre RGB. I am able to change color of other lights on both the keyboard and mouse, but not the Windows Lock, Brightness, and mouse DPI lights.

//Do not work, keys stay black.
keyboard[CorsairKeyboardKeyId.Brightness].Led.Color = color;
keyboard[CorsairKeyboardKeyId.WinLock].Led.Color = color;

Is this an issue with CUE or on my end?

[RobertBeekman]

Hey, I've asked Corsair about the DPI indicator before. It's intended to not be changeable through the sdk, sadly :c

[DarthAffe]

I couldn't reproduce this so far but I'm using a K95 and this could be keyboard related.
Could you try to run the 'color_pulse'-example provided with the CUE-SDK and check if the keys are correctly colored there? This would be the easiest way to see if it has something to do with CUE/SDK.

In case you don't have the SDK-code I just created a binary from it http://wyrez.org/uploads/color_pulse_example.zip

All keys are properly lit up in the provided example.

[DarthAffe]

Ah I was able to reproduce the behavior you described, but it's nothing related to some special keys.
Could it be that you use some brush which contains the brightness- and winlock-key?
If so you can't access the keys afterwards directly since the brush will always overwrite it. This could be workarounded by using the 'IsLocked'-Flag but the preferred way would be something like this:

CueSDK.Initialize();
CorsairKeyboard keyboard = CueSDK.KeyboardSDK;
if (keyboard == null)
    throw new WrapperException("No keyboard found");

keyboard.Brush = new SolidColorBrush(Color.Black);
keyboard.Update();

IKeyGroup specialKeyGroup = new ListKeyGroup(keyboard, CorsairKeyboardKeyId.Brightness, CorsairKeyboardKeyId.WinLock);
specialKeyGroup.Brush = new SolidColorBrush(Color.Aqua);

// Replacing the specialKeyGroup with this won't work even if it seems to be the same
//keyboard[CorsairKeyboardKeyId.Brightness].Led.Color = Color.Aqua;
//keyboard[CorsairKeyboardKeyId.WinLock].Led.Color = Color.Aqua;

keyboard.Update();

Let me know if this helps. If not we would need to investigate a bit further if the strafe uses different IDs or something.

[antonpup]

I don't use brushes, I set each key individually as shown prior. How would IsLocked workaround work?

But let me try making brushes for those two keys.

[DarthAffe]

Just set IsLocked to true before updating the keyboard like this: (And remember to unlock it first if you ever want to change the color.)

keyboard[CorsairKeyboardKeyId.Brightness].Led.Color = Color.Aqua;
keyboard[CorsairKeyboardKeyId.Brightness].Led.IsLocked = true;
keyboard[CorsairKeyboardKeyId.WinLock].Led.Color = Color.Aqua;
keyboard[CorsairKeyboardKeyId.WinLock].Led.IsLocked = true;
keyboard.Update();

But I'm pretty sure this will not help if you don't use brushes.

[antonpup]

I just tried with creating two brushes, one for winlock other for brightness. Same result, keys are not set.

[DarthAffe]

Ok this is weird ... could you please run something like this

foreach (CorsairKey key in keyboard)
    Debug.WriteLine(key.KeyId + ": " + (int)key.KeyId + " - " + key.KeyRectangle);

and post me the result?

I don't get it - looks good as far as I can tell.
One last test. Please run

CueSDK.Initialize(true);
CorsairKeyboard keyboard = CueSDK.KeyboardSDK;
keyboard.Brush = new SolidColorBrush(Color.Aqua);
keyboard.Update();
Thread.Sleep(5000);

All keys on the keyboard should be aqua then - how many/which ones stay black?

[antonpup]

That turned the whole keyboard aqua. I then tried this:

CueSDK.Initialize(true);
CorsairKeyboard keyboard = CueSDK.KeyboardSDK;
keyboard[CorsairKeyboardKeyId.Brightness].Led.Color = Color.Aqua;
keyboard[CorsairKeyboardKeyId.Brightness].Led.IsLocked = true;
keyboard[CorsairKeyboardKeyId.WinLock].Led.Color = Color.Aqua;
keyboard[CorsairKeyboardKeyId.WinLock].Led.IsLocked = true;
keyboard.Update();
Thread.Sleep(5000);

And the two keys stayed aqua color, as opposed to previously black. But I don't lock any keys in my original code, so I don't see why they won't set to another color.

[DarthAffe]

ok - at least there is a way to make it work. With he code like this it should work without the lock too.
You could take the code that is verified to work and only remove the 'true' parameter from initialize. If it doesn't work after that you have something running (a second SDK-program or a special profile in CUE) which forces these buttons to be black.

[antonpup]

Alright, problem resolved. Issue was on my side. My apologies.
