How to build your very own keyboard firmware

RtG · 09 Oct 2015, 14:32

Now I feel stupid - why didn't I think of that myself.
Thank you

HzFaq · 09 Oct 2015, 14:48

No probs, I only recently found out how much useful stuff is in there myself

.

Got any pics of what you're working on?

RtG · 09 Oct 2015, 18:44

Sorry no pics at the moment, all parts are scattered all over the place.
But I am building on a PC-MOD. Its a PC but it looks like a Laptop.
The last two pieces are about to get in place. Display and Keyboard.

Please update with pics!

I promise there will be pics.
My plan is to open a new tread with pics and explaining s.
Since a work accident I'm not the fastest worker any more.

If I wanted to hand wire a numpad, could I just use the lightpad TMK firmware and use all of the same pins on a teensy? The Lightpad also uses ATmega32u4 right?

Yes. (It's specified in Makefile.lufa in the lightpad directory.) (You can read off the pins used in matrix.c.)

Hey guys, Thanks for the help with this, all of you. I just wanted to show what I have so far, and hopefully I could inspire someone else to try. I have little to no experience with CAD software, and the code was very easy for me to change and modify to what I wanted.

The aperture on my phone is broken, so I apologize for the darkness of these images.
You can see the wires from the diodes are uncovered, but they do not contact the column wires (which are insulated by some sort of copper colored paint, so if they did contact, it would not matter any way. I took this insulation off the areas that I soldered to the switches). I am building a case for this as well, but for now (during testing) I am using motherboard standoffs. I also have a tip for anyone who is having trouble wiring the rows and columns to the teensy, you don't have to do it like I did, and send the wires to the end of each row/column you can hook them anywhere in that row/column. I just did it this way, and a lot of other people do too, because it was easier to trace the wires and figure out where they belong.
My Matrix (sorry about orientation)

Closer picture of matrix. You can also see my plate. It is aluminum that has been bead blasted in my college shop. I made the plate with a 1/16th inch end mill with help from some people from the Mech department at my school.

Here is image of my layout (or what it will be... also I just noticed the second "END" key... Will have to come up with something else to put there)The red outlined keys will be one color, and the green will be another. I am thinking Grey for the green section and a red for the red section. I have another design getting worked on right now, I will check back soon.

I will post more pictures, and update this post as time goes on, but this is what I have for now. Thanks for checking it out.
----------------NINJA EDIT----------------------------
This was originally a help request... I made very silly mistakes in code. I had b's where d's should have been.

Can someone please make the hex-file for me?

i dont get it!

Thanks!

flabbergast · 30 Oct 2015, 08:37

Well, you had a couple of typos in your sources. I'm attaching the fixed sources, and the dir also contains the compiled hex file. Not sure that it'll do what you expect it to do - I didn't actually check the C code, apart from fixing the typos that generated compilation error. Feel free to ask if there's more problems.

Tiny · 03 Nov 2015, 04:29

Can someone take a look at my files? For some reason I can"t seem to be able to type anything after flashing the micro.

nexaddo@gmail.com · 08 Nov 2015, 00:35

Hey guys,
I'm trying to make a small keyboard but I'm stuck at making the firmware. For some reason I get this error when I run make -f makefile

: Error Makefile.JPG (256.52 KiB) Viewed 6273 times

I've duble-triple checked all the code in the H60 folder but I don't seem to see any problem with it (considering that I mostly copy/paste-ed everyting....the tutorial was almost exactly with what I had in mind 15 columns and 5 rows.

gh60.zip: (17.8 KiB) Downloaded 141 times

I've attached the files if someone is nice enough to look at them and/or just compile them. Also I have Windows 10 installed so I'm not sure if that's the problem considering that make.exe had it's last update some 5 years ago.

gogusrl · 08 Nov 2015, 00:54

Hehe, a fellow romanian. I got stuck there as well earlier today and decided to try my luck with Soarer's (and failed there as well).

keymap_common.h:44:68: error: parameter name missing

This line says the error is on line 44, column 68 in keymap_common.h. You either have a missing parameter or extra comma. Assuming it's an extra comma, removing the comma and recompiling gives this error:

Code: Select all

keymap_common.h:45:75: error: macro parameters must be comma-separated

Going to line 45, column 75 in keymap_common.h you'll notice that there's a missing comma between the K4D and K4E parameters. Adding the comma and recompiling gives this error:

Code: Select all

keymap_poker.c:25:1: error: expected '}' before 'RNS'

Going to line 25 in keymap_poker.c you'll notice that there's a space between the 'T' and 'RNS'. Removing the space allows the code to compile successfully.

nexaddo@gmail.com · 08 Nov 2015, 03:05

well....I feel stupid...there I was trying to make a boot-able linux stick (which I plan on doing anyway just to have it)....Thank you joc, it actually worked.
@gogusrl...nice to see other keyboard-obsessed Romanians

Hey, I keep getting these errors on the cmd when I compile, even when I try to compile the gh60 right from the source.

Is that with the unchanged source?

The error message

looks like a pretty normal error in your keymap_poker.c file. If this is your code and you don't find the error, post your poker.c file.

Hey Halvar, thanks for your quick response. I tried that with my own source. Here is my poker.c file:

F0 in your first layer is an undefined keycode. Maybe you mean FN0?

You can look up the available codes in the file /common/keycode.h

Yes!!!
That was my mistake - I wrote my function keys as "Fx" instead of "FNx"!

Thank you, Halvar!

Halvar · 09 Nov 2015, 21:00

You're welcome! Does the keyboard work?

Tomer · 11 Nov 2015, 11:05

Halvar wrote: ↑You're welcome! Does the keyboard work?

After a few days of programming and re-soldering what apparently was a non-functioning diode, the keyboard works perfectly!
Thanks again for the help.
Now I need to figure out how to program toggle LEDs on my two toggle function keys and on my CAPS lock key.

zoomx19 · 24 Nov 2015, 02:45

I did all the steps and assigned everything correctly but for some reason all the keys arent mapped to the right switches, idk what to do help.

rockosmodlife · 15 Dec 2015, 06:38

hey guys, I have an issue that I cant seem to shake here.

Code: Select all

obj_gh60_lufa/common/keyboard.o: In function `keyboard_set_leds':
C:\Users\Administrator\Downloads\tmk_keyboard-master\tmk_keyboard-master\keyboard\gh60/../../tmk_core/common/keyboard.c:176: undefined reference to `led_set'
obj_gh60_lufa/common/keymap.o: In function `action_for_key':
C:\Users\Administrator\Downloads\tmk_keyboard-master\tmk_keyboard-master\keyboard\gh60/../../tmk_core/common/keymap.c:36: undefined reference to `keymap_fn_to_action'
make: *** [gh60_lufa.elf] Error 1

The above is what cmd spits out after trying to compile. I do not wish to include any LEDs or a FN layer. What items need to be edited to reflect a keyboard that does not have a FN layer or LED array?

I am no coder by any amount, but I assume that there are empty variables that are causing this error because I have not defined the led_set or a fn key or layer.

Thanks

Halvar · 15 Dec 2015, 11:25

Hi, welcome to DT!

Did you delete or edit the file led.c? Or the file keymap_common.c? Because these are the files where the function belong that cannot be found.

If you don`t want to use LEDs, you can empty the function led_set(), but you should not delete it.

Code: Select all

void led_set(uint8_t usb_led)
{
}

I would leave keymap_fn_to_action() untouched.

Code: Select all

/* translates Fn keycode to action */
action_t keymap_fn_to_action(uint8_t keycode)
{
    return (action_t){ .code = pgm_read_word(&fn_actions[FN_INDEX(keycode)]) };
}

Good evening all, has anyone any experience using any of the other members of the Teensy family? or possibly with an Arduino? I have a Teensy 3.1 and an Arduino Mini Pro. Wondering if it's worth pursuing these or wait for a Teensy 2. As a side to this, has anyone developed Bluetooth capabilities? I have an RN42HID on its way which I'll hopefully look to integrate into a project next year.

Thanks

Nic
