Level 20 Mouse Pad

[JesseHolwell]

Hey, first off - this software looks fantastic, amazing job.

I have a ThermalTake Level 20 RGB Extended Gaming Mouse Pad that I am trying to integrate into my home automation system so that I can set the lights with a batch file, and the IPC server trigger looks like it's going to get me there.

However the device is not supported, so I have attempted to add support to your codebase but I am hitting a wall and not sure how to proceed. I am assuming I have not configured the device correctly and am hoping you can give me some guidance.

First time using wireshark, but I can see the packet that is setting the setup data, just unsure which values are important here.

Here is my Debug Report:
I only have the one TT product, and if I remove the mousepad then all four 0x9007 lines disappear.

Here is my wireshark dump.
I went through plugging in the mouse pad, starting iTAKE engine, and setting all three LEDs to red
level20mousepad.zip

Thanks!

That wireshark dump looks really quiet, can you post another one where you change the color more? Maybe set each led to a seperate color or maybe run some effects.
It also looks like the mouse pad might operate using reports and not just sending raw data. It that case it might be difficult to figure out the full report layout.

Also for some reason its detected 4 times? Do you have 4 mouse pads?

[JesseHolwell]

Here is another wireshark dump where I go through the same as above and then switch profiles and go through different effects and colors

I'm unsure about the 4 showing up, only have the one mousepad.

Really appreciate your assistance

Yeah I dont think I will be able to implement this without actual mouse pad to test any time soon.

First you would have to add WriteReport/ReadReport to IHidDeviceProxy and implement them in HidDeviceProxy using HidSharp
Then use those methods in Init and SetRgb methods in custom Level20MousePadControllerProxy class.
The set rgb data seems to be 09 00 12 ?? 00 00 00 00 00 00 4646b9 4646b9 4646b9 4646b9 00 but not sure why only 4 colors, from pictures the mouse pad seems to have more. Not sure which reports will be the initialization ones.

[JesseHolwell]

Right so it uses a different technology than the other TT devices? I am regretting buying this mousepad more and more as time goes on 😅

Thanks for the write up about how to implement reports that is very helpful, I'll see what I can do.

Regarding the zones, the mousepad has 3 LEDs: 1 in the logo and 2 that go around the edges. It uses an optic fibre cable to carry the light all the way around and just blends the two colors together.
