[help] CM Storm liberation device

[nanu]

Hey guys, I've been out of the scene for a long while. Quite easy to do when you're feeling satisfied.

I recently picked up a CM Storm Quickfire Stealth. I would rather its Fn key be a proper Apps/Context Menu key.
So I want to replace the daughterboard on it much like bpiphany's HID Liberation Device, for Filcos. The current plan is to cleanly and minimally wire it to a Teensy++ 2.0 which I have, and then put hasu's or Soarer's firmware on it.

I could also get behind the idea of possibly treating the App key as a Fn key for accessing a layer for keypad keys and the like.

Here's what I have figured out so far, here.

Code: Select all

Cooler Master Quickfire Rapid Stealth pinout and matrix

I lurk the following relevant, recent thread but I'm sort of lost, there, too:
http://deskthority.net/workshop-f7/filc ... t5751.html

What's the next step? I'm looking at various tmk_keyboard ./keyboard examples.
Am I free to pick which pins on the Teensy++ I can map these pins to?

Thoughts in my head:
I think I need 4 PORTs worth of pins.
Is there a GUI or script or the like that can generate the relevant C code?

Just fyi, I believe bpiphany is working on a daughterboard for it already, or at least he intended to recently. I even belive someone sent him one for him to work on along with a rosewill I believe. I'd check up on that before continuing. If he stopped that, I fully support your endeavor.

It's going to be real on Monday I hope, if I didn't botch anything up... The matrix is already mapped out here in the wiki =)

[nanu]

Thanks for letting me know! I normalized my matrix and it matches (at least as wired to a tenkeyless).

BTW, pins 40 and 10 (blank in the matrix on the wiki) route to the Fn key which I desire to be a working APP key.

Fill it in ;) It will of course be accessible since it is a hole in matrix rows and columns used for other keys. I'm only writing really basic firmwares myself. I leave those tasks to other people =)

Done: I added a note below, because depending on reader's intent, the matrix is strictly the layout, or, what key code the original controller sends.

To that end, if they wanted to reuse the original controller, then someone ought to label all the Fn's... I might end up doing that myself, but it's not yet planned..

[bpiphany]

It works! =D Only a few bugs that came out easily...

Heh, I love that design.
