qmk_toolbox VS qmk_firmware

Flashing custom firmware - the current version QMK tool off the website won't work. You'll most likely get a "USB device connected (NO DRIVER): WB Device in DFU Mode " and not be able to flash anything. You will need the beta version that supports WB32 flashing utility. I grabbed mine from the GMMK guide QMK tool from GMMK

You first have to download QMK toolbox https://github.com/qmk/qmk_toolbox/releases/download/0.2.2/qmk_toolbox.exe. Once downloaded, download this bin file https://github.com/GHv4/Sense75-CAPSLOCK-UNDERGLOW/blob/main/sense75-CAPSLOCK%20UNDERGLOW.bin. Open the QMK toolbox exe file, then hit the open button. Locate the .bin file. Hold Right FN+BACKSPACE until it pops up in QMK Toolbox. Hit flash and wait for it to finish flashing. Via and Vial compatible. YOU'RE WELCOME FRIENDS!!

Flash it with qmk toolbox: https://github.com/qmk/qmk_toolbox/releases

I got things working by using the https://github.com/qmk/qmk_toolbox project, and the firmware file you linked. As you said, my pad now works with Vial, and has 12 layers. Though the layer selector still only traverses between layers 0 through 3.

- QMK MSYS: you'll need it for many things, for compiling your firmware file and for flashing, especially if flashing with QMK Toolbox isn't permitted in firmware settings (in this case QMK Toolbox just won't recognize your keyboard);

I am currently using the QMK online configurator tool to do the compilation and download the resulting .bin file, and then the QMK Toolbox to flash it onto the keyboard.

Check out this site: http://kpchn.com/s/PoHJ. I found it from the AliExpress page and it leads to all the VIA/VIAL configs for the KPRepublic boards. Go into CSTC75 and you'll see a .hex file, that's the firmware. You should be able to use the QMK toolbox: https://github.com/qmk/qmk_toolbox to flash the firmware.

Tool needed to flash your keyboard (QMK Toolbox) can be downloaded here: https://github.com/qmk/qmk_toolbox/releases/tag/0.2.2

When I first plugged them in, my Mac (running 13.1 Ventura) recognized them as a USB storage device. I was trying to use the QMK toolbox to flash the firmware onto them, not realizing that I needed to drag and drop a .uf2 file instead of trying to flash a .hex file.

I agree that reduced finger movement is a crucial step in achieving typing efficiency. This is nicely solved by mod tap modifiers in QMK/ZMK[1] where key acts as a char when tapped and as a layer while pressed.

If you have a keyboard that runs QMK firmware[0] with the VIA[1] feature enabled[2], then there is a convenient testing app available from the same place you customize your keys [3].

I made a layout that I'm happy with. Spanish is my native language, so it has characters like the accents and 'ñ', but it's meant to be used for programming as well. Visual Studio uses a lot of Ctrl and Ctrl + Shift shortcuts, so I left them in the same place as the default Corne layout so I can press them both with my pinkie finger. Perhaps some of the ideas are useful to you.

Also, it would be possible to do this for the RP2040. However, it needs some work to get working. but for example: https://github.com/qmk/qmk_firmware/pull/20999

Ok, it's an ST7735, not too different from the ST7789. You should be able to get running by looking at their files in the QMK repo and going from there. You should also check their resources page.

UPDATE: after fluffing around a little bit, I have manged to fix this code: https://github.com/qmk/qmk_firmware/blob/master/keyboards/lily58/keymaps/bongocat_wpm_responsive/keymap.c and flash it successfully - it seems not to be working correctly as the cat is only hanging there and does not respond to the wmp count. If anybody spots anything wrong in the code please let me know!(C is not my language but I am a programmer, I am gonna get at it again over the weekend if I have time left)
