NOT pitchfork worthy yet but, interesting none the less. Personally i only want one color at a time so I would care less either way if i had one. FURTHER more I have seen cases where circuit designers get contracted on to companies for products, get in big trouble when it hits shelves fails to work and it turns out the Chinese manufacturer cut out out a ton of components with out conferring with the original designer.
First Samsung 840s then the keyboard. whats happened to QA lately?

If that were the case, then instead of it being the green channel that doesn't support 256 colors, it is the alpha channel (which I'm pretty sure isn't present, just uses HSB) - still the same issue of not having a smooth transition. I'm pretty sure I also tried what you described to no avail, as well.
Based on what I'm seeing, a byte sent to the device covers two keys instead of one. Take "0x77" for example with keys "F8" and "8":
When it is set to "0x07", the "F8" key will have one of its channels maxed out while the "8" key will be 0.
When it is set to "0x70", it is the opposite.
Now, had it been that "0xFF" (for example) was a value for ONE key, it would indeed support 16.7 million colors. As it stands, we don't even know if the device itself can support 16.7 or if it is a firmware limitation.

It depends how they plan to implement the Lua scripting. Depending on how powerful the processor is on the keyboard, it is potentially possible that the Lua code would be interpreted and ran directly on the keyboard's chip instead of on the PC (with resulting data being piped to the keyboard). If that's the case, it would bypass the 3-bit USB limit. This, of course, is extremely wishful thinking... Assuming the chip is a fit-for-purpose display controller (which I think was announced) then I doubt it can run custom software (i.e. not able to run a Lua environment).

We need a teardown of this thing so we can see exactly what chips are inside. That would clear up the hardware software question pretty quick. My guess is a dedicated LED matrix driver along with a general purpose microcontroller, ARM has been mentioned before, that interfaces the key matrix, LED driver, and USB together. How the Lua implementation works will depend upon the memory and speed of that microcontroller. They already mentioned that the micro doesn't have much memory for HW profiles, so unless the Lua engine is already in the firmware I doubt they'll have room to add it. My guess is that everything continues to be PC-side driven, but being able to run scripts on the keyboard's processor would be great if true. The interface for moving custom data inputs to the embedded side would also be a mess in that case.

Again, NONE OF THIS IS CONFIRMED, it's just my quick electronics engineering detective investigation given the limited information we have available, but this puzzle fits together all too well. If someone has already ripped the logo off their K70 (or K65/K95) to reveal the screw likely hidden beneath it and wants to completely tear it down I'd really love to know if this is indeed the chip being used. As far as I can tell it's the only Panasonic LED matrix IC that fits the bill.
