deskthority

You're right, I am thinking of a wooden case and plastic sheets to ensure insulation. Also I've got elongated nuts, which I can put on the bottom of the plate to leave space to the wires. Dunno if they are long enough! I'll show here the polished result

Here it is:

@Anakey, @Laser and @matt3o, you are my gods…

EDIT : I've edited the title to show that the keyboard is done.
EDIT 2 : You were right @matt3o, I got shorts

OK !! Now this is a success. I am currently writing these lines on my brand new keyboard. I am not acquainted yet with the orthogonal matrix, but it comes fastly. :-))
I need to perfect it, because for now I have no arrow keys, Windows or Del key (only backspace) . But this is already a good result ...

Wow! As simple as a macro. @Anakey, love forever :-)
@Muirium: You've got your answer!

I think I'll have to adapt this because I forgot I have flipped the keyboard upwards, so that Row 5 is actually Row 0. So it I guess it would become:

#define KEYMAP( \
K00, K01, K02, K03, K04, K05, K06, K07 ...

So I've produced a keymap showing translation into the actual matrix:

OK, issue posted on Github.

Thank you @anakey! I will look into this!

I see! the matrix stings my eyes

Maybe I should ask the qmk developers themselves.

@matt3o thanks for your answer. I will cut the wires.
@muirium @Laser thank you both for your answers!

Now I've got a question about my mapping. My mapping is quite messy (although I understand it well). But it will become a headache to transform my key mappings into the tables in the keymap.c file ...

Yooohooo! Got working at last.

What I did:

- I added "BOOTLOADER = caterina" in the rules.mk file.
- I ran "make lebarde:bepo:avrdude" as simple user. Had errors, then:

~/dev/qmk_firmware$ avrdude -p atmega32u4 -P /dev/ttyACM1 -c avr109 -U flash:w:lebarde_bepo.hex
Connecting to programmer ...

@Laser Thank you for your answer!

So, I have tested quite a good things. I even think I had started to brick my Pro Micro card. It seems it is now OK.

1. It seems dfu-programmer never finds the board. How to target it?

root# dfu-programmer atmega32u4 erase
dfu-programmer: no device present.


2 ...

I've got quite far now. I have git-cloned qmk and created my own keyboard directory. QMK is building fine, the Pro Micro card is recognized, but I get this with Avrdude:

~# make lebarde:bepo:avrdude # with user ROOT
QMK Firmware 0.6.266
Making [1mlebarde[0m with keymap [1mbepo[0m and target ...

OK now I have wired everything. Normally it should be OK.

I realize I made a little mistake. I misplaced the diodes as they are on the rows and not on the columns (see the former photo). In that way the current matrix should be OK: I only have to cut the rows to get the last 4 switches together, cut Row 3 in two, and reformat the columns.

If I have not ...

OK! Here is a mapping I imagined. Don't hesitate to open the picture in full format because it is a bit tiny.

A little explanation: the rows (turquoise blue) don't have to be ordered because there is no diode on them. This is why I could choose C1R7 to be at that place. If I wanted to follow the ...

Oh thank you very much matt3o, I think I understand now.

So, I currently have 15 columns and 5 rows, i.e. 15×5 = 75 keys, and 15+5 = 20 in/outs.
I want to have up to 18 in/outs with at least 75 keys.

$ 15×3 = 45
$ 14×4 = 56
$ 13×5 = 65
$ 12×6 = 72
$ 11×7 = 77 (bingo!)
$ 10×8 = 80 (OK)
$ 9×9 = 81 ...

Thank you for your answers! For now, I think I will:
1. Try the hard solution (re-wire the switches), but I don't know how to proceed to do what matt3o suggested with the diodes.
2. If I don't understand / cannot do it due to pins limitations / don't manage to do it, I think I will go to Arduino ...

Thanks for your answer, but I don't see what to do with the diodes...

Yeah, cool! Actually I only have to add 10 wires, this should not be too coarse... And then I will have to dive into the controller response and testing...

Thank you matt3o, I think you saved my day

What do you think of this wiring?

I am currently redesigning a shape I want to submit to you

EDIT: Thank you @laser, if I cannot get out of this I will likely go to that...

Thank you matt3o for your answer. Actually the wiring is done (I could undo it if really needed) and the last row is used a lot...

And what about a silicone drop from your best glue gun?

What I have done is to put different keycap shapes on that keys. For instance, I put some upper Fn keycaps which I turn left for F and right for J. In that way, when I place my hands on the keyboard I can feel those keys going a little upper than the others. This is discreet.

But in my case, the ...

OK, now I am ready to go on this project, but I am stuck with one problem that prevents me from going on.

My new keyboard has 15 columns and 5 rows. If I understand well, my controller needs to have 15 outs and 5 ins (or reverse). But if I am using a Pro Micro, it has only 18 pins if I except three ...

Hello my friends. I received the plate and pro micro board, so I assume I am ready now to flash the firmware. I work under Linux, so I will have to dive into the flashing process for an arduino board, or find how I can fully flash the arduino firmware (in that case the board would not be recognized ...

Thank you. I will dive into that, ship some boards and tell you here.

Hello,
I purchased copies of Arduino-nano boards on aliexpress. As they were around 1-2€ each, I purchased 3 of them, should I burn one into flames. :evilgeek:

The cards went with separate pins I had to solder. Here is in the bottom what I got.

Now, I would like to use the QMK firmware, but I don ...

Hello,
Thank you both for your messages. Actually I have received the keycaps, microcontroller card and blank keycaps. So now I could start and build it. I will have to get into the case dimensions and make decisions on design! I will write back here my experience.

I just got a bunch of switches from Massdrop. I ordered Kaihua copper switches. They are tactile. I shall see if that's good for a typist keyboard!

I got 120 switches for 32 €. To be continued!
