Very Large Matrix Build.

I'm building a very large keyboard. It has 25 columns and 6 rows. I wired up a Teensy++ 2.0 because of its many pins.
I'm having a bit of trouble finding some code which I can adapt. I attempted to follow matt3o's tutorial on modifying Hasu's code, but I think I have too many columns. I've never been very good at C, so I tried using the stock Arduino code, and again ran into the problem of having too many columns.
Why so many columns? Most people seem to want very compact keyboards, but I never seem to have enough keys. I wanted a keyboard with many keys such as F13-F24, media, power control, numpad, and I didn't want to use any stabilizers. I also didn't want a space-bar, so I put a row of thumb keys in its place. The key-count grew quite large.
I'm using a variety of Cherry MX switches: browns for the regular keys, blues for the function type keys, reds for backspaces, and a few others peppered about.
Does anyone have any code for a Teensy++ 2.0 with a matrix of at least 25 x 6?
Thank you,
SalsaVerde

Awesome board. I'm a fan of big boards even though I don't typically use the numpad. I know you're looking for firmware help in this thread but I've got to ask, What kind of a case are you planning to use? and how exactly are you mapping that bottom row?

I'll look into it. Thanks for the lead.

Thank you.
I'm building this one as a prototype, so I'll just cut some maple to close the bottom. I have some fancier plans for a wedge-like aluminum case which I will fabricate.
The thumb row is laid out like this:
Control OS ALT Function Backspace Delete Space Enter ALT OS Context Control

With hasu's code you could use a 13x12 matrix (significant resoldering required). The controller matrix doesn't have to follow the physical layout. It's easier if it does but not very efficient. 25x6 needs 31 ports, 13x12 only 25.

Yup. Squarer matrices are more efficient on pin use. (Add the rows and columns.) But what you save in pins, you pay for in complexity when figuring out exactly where the switches are.
As a fellow C- student, I recommend Soarer's Controller as well. That thing's magic. Here's the config for my custom 60%. See if you can grok it. The matrix is defined at the top. That's all you really need. There's a load of macros and remaps in this too!

No code required with Soarer. There's a firmware for the Teensy++ as well as the little one I use in his zip file.

Thanks for the code. I'll review this and report my progress.

Gentlemen, I got it working with Soarer's controller.

(Sorry for the mess. Looks like tabs didn't get translated well.)
One thing I haven't been able to figure out yet is getting a single button to do a macro, I guess. I want one of the switches to trigger a CTRL-ALT-DEL. I couldn't see exactly how to from the examples. Thoughts?
Thanks,
SV

You define a key to issue some nonsense code, say F20... then define F20 to be the macro.

I'm actually using F13-24, so I chose an AUX code for that macro, which worked. Thank you.
Code: Select all
macro AUX1
MAKE LCTRL
MAKE RALT
MAKE DELETE
BREAK LCTRL
BREAK RALT
BREAK DELETE
endmacro
Now, I'm trying something a little different. I'm trying to send Unicode characters by ALT and keypad numbers. For example, this one sends an acute accent:
Code: Select all
macro AUX3
MAKE LALT
PRESS PAD_0
PRESS PAD_1
PRESS PAD_8
PRESS PAD_0
BREAK LALT
endmacro
Code: Select all
macro AUX3 SHIFT
CLEAR_META all
MAKE LALT
PRESS PAD_0
PRESS PAD_1
PRESS PAD_6
PRESS PAD_8
BREAK LALT
endmacro
In this one, I'm attempting to send an umlaut using SHIFT and the AUX key, but the shift is preventing the number keypad from sending numbers. I tried various ways of cancelling out the depressed shift key, but I can't get it to be ignored. Is there a way to ignore any physically pressed keys while a macro is executing?

How about sending
BREAK LSHIFT
BREAK RSHIFT
at the beginning of the macro? It's analogous to how I do it in AutoHotkey, only in my case the modifier in question is the right Windows key.

I found a workaround, but it's clunky. It assumes and requires that NUM_LOCK be on (which it always is for me).
Code: Select all
macro AUX3 SHIFT
PRESS NUM_LOCK
MAKE RSHIFT
MAKE LALT
PRESS PAD_0
PRESS PAD_1
PRESS PAD_6
PRESS PAD_8
BREAK LALT
BREAK RSHIFT
PRESS NUM_LOCK
endmacro
This turns off NUM_LOCK, presses and holds shift (which makes the keypad work for ALT+###), then punches in the unicode for an umlaut, then restores.
If anybody thinks of a better way, I'm all ears.

I closed the case with some maple and a 1.5mm sheet of laser-cut stainless. It's ridiculously heavy. I ruined a countersink bit drilling in the stainless, so the screws aren't totally flush. Stainless steel is really tough stuff.
I found some 1.5mm thick clear rubber feet on amazon.com.
The next one will be aluminum, and a little fancier, but this turned out alright for functionality.
The two light gray keys are space. They were black before, but I needed a way to orient myself while I get used to the layout.
The machine screws hold the wood frame solidly.

This is so awesome. I love battleship builds.
