How to build your very own keyboard firmware

[Halvar]

Congratulations on getting it to work, that looks like a very nice keyboard. Beautiful keycaps!

IMO it's better to do the mapping on the side of the PC operating system. You could write macros for it in the firmware (i have no experience with this yet, but I know it's possible), but its much more of a hassle and rather unelegant if you ask me. There's a short documentation for that in Hasu's code repository.

It is quite a beauty!
I would personally do this in firmware, because then I will only have to do it once
TMK can't do that out of the box if you want shift reported to the OS normally, but it's 20 lines of code or so if your shift-layer is accessible on a normal keyboard with shift (as "+" is on the Numpad, i believe). On the OS-side though, you can do are not restricted by existing keyboard layouts.

But are the printed legends enough anyways? you might want to have tab and alt somewhere. Together with that awesome caps/func key.

Hey everyone,

Need a bit of help with loading my tmk keymap unto a keyboard.

I've just finished defining a keymap for a planck that I have coming in the mail. I don't have any of the other files, as the seller told me that they're already burned into the planck's controller. I followed some guides on how to define a keymap, and looked at examples of others, so as of now, all I have is this, in .txt form.

Code: Select all

#include "keymap_common.h"

const uint8_t PROGMEM keymaps[][MATRIX_ROWS][MATRIX_COLS] = {
[0] = KEYMAP( /* QWERTY BASE */
  TAB,		Q,		W,		E,		R,		T,		Y,		U,		I,		O,		P,		BSPC,

  LSFT,		Z,		X,		C,		V,		B,		N,		M,		COMM,	DOT,		SLSH,	FN3,		
  ESC,		CAPS,	LGUI, 	LALT,	FN1,		SPC,				FN2,		LEFT,	DOWN,	UP,		RGHT),

[1] = KEYMAP( /* FN1 numbers, hold */
  TRNS,		1,		2,		3,		4,		5,		6,		7,		8,		9,		0,		TRNS,
  TRNS,		TRNS,	TRNS,	TRNS,	TRNS,	TRNS,	TRNS,	TRNS,	TRNS,	MINS,	EQL,		TRNS,

[2] = KEYMAP( /* FN2 numpad, toggle */
  TRNS,		NO,		UP,		NO,		TRNS,	TRNS,	TRNS,	7,		8,		9,		MINS,	TRNS,
  TRNS,		LEFT,	DOWN,	RIGHT,	TRNS,	TRNS,	TRNS,	4,		5,		6,		FN4,		TRNS,

};

const uint16_t PROGMEM fn_actions[] = {
    [1] = ACTION_LAYER_MOMENTARY(1),
    [2] = ACTION_LAYER_TOGGLE(2),
    [3] = ACTION_LAYER_MOMENTARY(3),
    [4] = ACTION_MODS_KEY(MOD_LSFT, KC_EQL),
    [5] = ACTION_MODS_KEY(MOD_LSFT, KC_SCLN),
};

What are my next step's from here? If my understanding is correct, the last step would be to load a hex version of this unto the teensy using the loader. But I'm quite unsure as to how to transform this into the hex file.

[Ray]

with tmk, you have to compile the whole thing – not only the keymap – to a .hex (you should be able to find info of how to do that)
that's different e.g. with soarer's, where the keymap is not part of the firmware itself, but more like a configfile for it.

You need to compile the code. If you look at the start of the first part of the guide it says to download and install WinAVR, and near the end of the second part it talks about compiling with the command make -f Makefile in a command prompt, that will produce the hex file.

Key caps are double-shot ABS, the orange BASIC function legends on the front are dye-sub or something like that. The switches are inverted cross futaba's, so close to MX mount but too fat.

Well my project is to turn the Acorn Electron into a computer with a Raspberry Pi 2 in it (maybe a Intel NUC later on), converting the keyboard to USB is the first part of that. I also plan to wire up a switching USB cable so the keyboard can be used for the Pi, or as a standalone keyboard on any other PC with a USB-B or Mini-USB port on the back.
So with that in mind i wanted it all in firmware so it can be used on anything.

I'll try and do it in firmware as i'd prefer it that way as well, i'll just have to play around and see what i can do.
I know about the OS side being more flexible with stuff like AHK, i use it on my main board since i have DSA Dolch caps on a UK board so i made a program so the output matches the caps.

There aren't really enough keys for a fully functional layout but it's good enough. I probably won't be using the board a lot, i just like doing projects and this was part of the larger one i'm doing.

[Caeyden]

I see! So even though I've made the keymap myself, I still have to run through the entire process using the guide? That shouldn't be too hard then.

[XRA]

this thread has helped a ton getting things setup here, but I think I'm hitting a wall & not sure if it's a simple thing I'm overlooking or more complicated.

I'm working on using a Teensy 2.0 w/ Hasu's firmware to convert a Toshiba T3100e keyboard to USB,
it has a 22 pin ribbon cable off the keyboard, according to the T3100e manual it looks to have 11 columns and 8 rows (& 3 common grounds). It also has the column pins are marked as OUT and rows are IN. (im assuming SC is column and RTN is row)



I checked continuity for all the keys with the 22 pins and determined the key layout in rows/columns in a spreadsheet, i need to finish marking the keys K** to match up with my code...


When I first tested the keyboard using 11 columns and 8 rows, I got no keys working, and also no voltage drops at a row's pin, when a row is trigged by pressing the relevant key.

So because of that I assumed the diodes are facing the opposite way..

so then swapped around the rows and columns in code, so it has 11 rows and 8 columns:

this is the current keymap_common.h

Code: Select all

#define KEYMAP( \

Now with that change, some keys do things, but none of them are correct, and the only unique character/codes i can get are the following (I tested all keys), they don't seem to relate to any sort of pattern in the rows/columns either...

3 f d n e b 4 a g , END 5 F6
(I also highlighted them blue in the spreadsheet above)

When I check the voltage on the row pins, it is dropping correctly when a row is activated- so for example I can press any key of a specific row, and that row's pin on the Teensy pcb will drop in voltage, which I believe means my wiring is correct/

But as far as where to go from here, I'm feeling stuck, I've been doing changes in code, like reversing the ordering of rows or columns but having no luck so far..

I've also tried disabling NKRO and enabling matrix_has_ghost and playing around with other config options

any suggestions are extremely appreciated!!

Now with that change, some keys do things, but none of them are correct, and the only unique character/codes i can get are the following (I tested all keys), they don't seem to relate to any sort of pattern in the rows/columns either...

well, that's strange. If it is on software or on hardware, either way, it would be related to rows/columns…

Can you check that the pins in matrix.c are the actual ones connected to the ribbon cable?

keymap_common.h looks good enough, as does keymap.c
as long as it compiles, your problem doesn't sit there.

to sum it up:
you got a keyboard matrix where you tested every switch for continuity at the ribbon cables. You double checked the rows/colums while doing so.
you got a KEYMAP that fits that.
only 13 keys register something.

at that point I would double check my wireing and soldering.
and check if my changes in code are actually compiled.

thanks for the suggestions! I started making sure it was compiling my changes, I ended up clearing some unused files, (all the keymap c's i wasnt using since i started with the gh60), as a result I modified the makefile to point to just the specific keymap.c

there still wasn't a difference, but then while looking in the makefile I tried commenting out these lines:

Code: Select all

#BOOTMAGIC_ENABLE = yes	# Virtual DIP switch configuration(+1000)
#MOUSEKEY_ENABLE = yes	# Mouse keys(+4700)
#EXTRAKEY_ENABLE = yes	# Audio control and System control(+450)

and now everything works as expected, all keys are fine, just one column pin has a loose connection that i'll fix

I'm not exactly sure why those build options were causing trouble for me, but I'm really glad it is working finally!

Can someone help me with this configuration problem:

IMG_0168.JPG (50.92 KiB) Viewed 7225 times

My guess would be, that it has to do with hexadecimal counting, because col17 and col18 don't work anymore. All the other keys on the keyboard work. It is a software problem, no hardware problem, because the same hardware worked flawlessly before with Soarer's firmware. Here my configuration files.

[hasu]

Probably this code are handled 16bit integer and col16 and col17 bit are ignored.

Thanks for any help!

[shaymdev]

In your key map file after each keymap(...) you need a semicolon.

[ambergrismonger]

I put semicolons where you described and I got:

keymap_poker.c:8: error: expected '}' before ';' token
make: *** [obj_gh60_lufa/keymap_poker.o] Error 1

[ambergrismonger]

Figured it out thanks to you Shaymdev, there were supposed to be comma's after each (...) on the poker_keymap. Time to flash, cross your fingers for me!

[shaymdev]

Oh yeah commas, I totally meant commas. I ran into the same issue earlier this week. [SMILING FACE WITH SMILING EYES]

[ambergrismonger]

So, I flashed the firmware and the keyboard goes crazy firing random keys and freaking out in general. Here are all of the files that I edited. Thanks for any help!

[Boywonder]

Could Someone help me compile my code? I have no clue how to and I honestly don't understand how I would go about compiling it. Any help or advice or tutorial would be greatly appreciated. I modified all the code in the gh60 directory and the poker keymap directory, just like the tutorial, however I don't know how or what to do to open the GNU GCC compiler or terminal and then turn it into a hex file.
Thanks

[ambergrismonger]

I figured out my first issue and got my keyboard working! Unfortunately the fn buttons aren't working. When I press the FN1 key it registers as an 8 keypress and when I press FN2 it registers as g. Any idea what's going on here? Everything else seems to be firing right.

[Boywonder]

So I figured out how to compile my code, however now I get errors saying that say this

No idea what its doing and I've tried getting the newest firmware from github, still no success.

[Halvar]

The important part are the first error messages shown:

Code: Select all

In file included from keymap_poker.c:1:
keymap_poker.c:5: warning: implicit declaration of function 'KEYMAP'

So what's going on in your keymap_poker.c file around line around line 5?

Show us the first 10 lines or so...

Thanks for responding! So I got all the code to compile now however, after loading it onto my teensy, the bottom three rows dont work! The top two work fine, yet the last three arn't working properly. Instead of normal output, some of the keys open the start menu, while others are acting as arrow keys. I checked all the wiring and I can't find a short.

Here is all my code

I have no clue what is wrong, and I've looked over my code so many times. Slowly I am learning

Thanks for any and all help!

This part looks suspicious, although I think it doesn't fit the problem you see:

Which pins are you using, D0 D1 D2 D3 D5 as it says in the comment, or F0 F1 F2 F3 F5 as it says in the code? Also seems like you're "unselecting" the wrong bits.

I'm using f0 f1 f4 f5 f6, the row pin config was from the software that i downloaded, but its greened out (annotation)

[Halvar]

OK, then check the select_row() function. You're setting F0 F1 F2 F3 F5 there at the moment.

Ahh success..... almost. so now almost everything works, except row 3 is firing 1qaz(alt), b doesn't work, and when i press g it also triggers a

Where could these problems originate from?

[flabbergast]

@Boywonder: I'm not sure this will solve your problem (which might be a diode backwards?), but you should also initialise the C7 pin you're using for column 15:

Code: Select all

    DDRC  &= ~(1<<7);
    PORTC |=  (1<<7);

in the init_cols function.

EDIT: (What I wrote before in the edit was completely wrong.)

Thank you very much! I'm typing on it right now!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! woooooooooo except my B key doesn't work might e a ad switch

No worries. Glad it helped!

For the 'B': check the diode, and the switch by itself with a multimeter.
