You shouldn't need to, since we're not using micropython. The stm32f4 has 3 native ways of programming it, that is dfu, serial, or swd

Thanks. it is an ender 3 v2

yes, these are just for pulling up the floating pins

did u try to connect to it with an stlink?

@@dewe1144 okay so i got it to work i had the black pill i changed the name and it worked but im using a 84 keys im a little confused on what to do to change out the buttons but rn i got 16 by 6 not 5 by 15 where do i changed the key outputs is it only in keymap.h??

@@dewe1144 if you got a discord channel i can send you how i got it wired up

how to you add another row? i got it to work but im tryingto add the F keys to pa11 and it keeps failing

i am currently typing on the keyboard =)

i didn't have the stl for low profile keycaps

Would you be able to modify one if I gave it to you? Of course I would pay you for your efforts

I would love to see a dye-sublimation process video! Those blank white caps came out amazing and definitely have an appeal all their own, i've just been interested in making my own keycap set, so i've been interested in the dye-sub process (there's not many super informative YT videos going from the design process to the finished product).

a 3d printed mouse or a 3d printed keyboard switch that works (hint) optical switches as they dont need copper they just need a spring

@@bobbyhutter5654 Hmm, I didn't know much about that, but from what i've seen, it requires a decently high heat for the ink to soak through the plastic, and i'm not quite sure that a 3d printed PLA plastic can withstand that amount of heat since it melts at 60C. But thanks for the suggestion.

@Yakko Does Stuff I've just recently bought a PMW3360, but haven't tested it or designed the pcb yet. So maybe in the future

@@dewe1144 ahhhh I didn't think this through 😅

which upper wire? if you want the schematic diagram, you can find it in the GitHub link in the description

Thanks!

Thanks. The source code is under the github link in the video. you can change the keycode mapping in src/keymap.c with the key definition macros provided in include/keyboard_usb.h. and the position of the FN key in src/main.c. Although you would need to pay attention to the wiring

it was an ender 3 v2, 0.4mm nozzle, 0.2mm layer height

i think it was around $7 - $10. I used cheap sunlu PLA+ filament

Thanks man

it took almost 2 months for me since i need to retweak my designs and build my own firmware, not to mention that i took a lot of break. But if you're trying to replicate it, it wouldn't take more than 2 days

Thanks!

lmao

why not, it's a DIY project for fun

Thank you

nah i think he did better, but thanks anyway lol.

have you entered boot mode? to enter the boot mode, press the boot button, and while holding the boot button down, press the reset button.

@@dewe1144 the program is dumped but the keyboard was not working

@@dcl3d have you tried uploading a simple blinky sketch to the microcontroller before?

@@dewe1144 not yet bro I will try. Thanks for your time

I'm using FTDI module for programming, but which RX & TX pin I need to use for dumping program in black pill. A9 & A10 is already soldered in keyboard. What should I do?

Thanks for watching! The programming part shouldn't be much of a concern since this project is made with PlatformIO IDE extension on VSCode. It basically converts VSCode into an IDE and handles the unnecessary build stuff behind. All i needed to do was code and press upload similar to the Arduino IDE. You can also change the flashing method to USB to TTL instead of stlink by modifying "upload_protocol" value from "stlink" to "serial" in file platformio.ini in the project directory

@@dewe1144 Okay cool that makes sense! So I'm gonna go ahead and buy the MC without the ST Link because that's even more pricey then the MC 🤣 I'll buy a USB to TTL and connect the appropriate pins, I guess. Do let me know if there's a mess up in my logic. But otherwise thanks a lot :)

@@SaketVaibhav Ur welcome. Few notes though, the backplate of the keyboard in my 3d model does not fit that well with the keyboard main frame. so i had to use a couple of zipties to hold them together lol. It's still pretty seemless though, so watch out for that or you could design the backplate yourself.

@@dewe1144 Hey thanks a lot! I have idea for that. I'll definitely let you know once I'm done. I don't think I'll have a flawless product since this is my first ever build :D But I can't wait to get it done :) Thanks for the motivation :)

@@SaketVaibhav Thanks man, really appreciate it!

Thanks!

Thank you!!

well the standard pcb layout would also need a microcontroller to read the switch matrix and translate it to usb. Now if i assume the standard PCB layout uses the microcontroller similar to an arduino (ATMega series), then yes, this one would be better because i used a faster microcontroller which is capable of a higher poll rate (1000 Hz). I'm not sure though since the firmware i used is built by myself and it's pretty crude

I bought it from a local online shop, its called SoundTech 2.1
