[Please help] my custom keyboard is not responding to the QMK firmware

Learning and discussion Custom keyboards

Hi there, I need some helps, I have been researching and updating the firmware file, and still can’t get my keyboard start typing at all

here I have made my custom qmk firmware

this is the qode looks like
keymap.c

#include QMK_KEYBOARD_H

#define DEFAULT_LAYER 0

// Define the keymap
const uint16_t PROGMEM keymaps[][MATRIX_ROWS][MATRIX_COLS] = {
    [DEFAULT_LAYER] = LAYOUT_split_5x16(
      KC_GRV,  KC_1,    KC_2,    KC_3,    KC_4,    KC_5,    KC_6,    KC_7,    KC_8,    KC_9,    KC_0,    KC_MINS, KC_EQL,  KC_BSPC, KC_NO, KC_NO,
      KC_TAB,  KC_Q,    KC_W,    KC_E,    KC_R,    KC_T,    KC_Y,    KC_U,    KC_I,    KC_O,    KC_P,    KC_LBRC, KC_RBRC, KC_BSLS, KC_NO, KC_NO,
      KC_CAPS, KC_A,    KC_S,    KC_D,    KC_F,    KC_G,    KC_H,    KC_J,    KC_K,    KC_L,    KC_SCLN, KC_QUOT, KC_ENT, KC_NO, KC_NO, KC_NO,

I compile correctly in the qmk toolbox and flashed it successfully, however the keboard still not responding to it

I really can’t figure it out
please help!!!

I have a few ideas, mostly my own learning by doing. Do you have any key working or is there just no response at all? I didn’t really find anything according to the keyboard name, that makes it a bit trickier :slight_smile:

  • One of my mistakes was wrong Pin naming, not sure about the atm32u4 and should also depend on ProMicro/directly attached in your case.
  • Diode direction could also be an issue, you can try to swap that to ROW2COL.
  • If you’re using a ProMicro, is it soldered on the right way around? If you can flash it I doubt there is a short, so that’s more unlikely.
  • if you have a Multimeter, check your Matrix connections from the MCU pin to the diodes/switches for continuity, just to make sure your electrical connection is there

If you have no keys that are currently working at all, I would bet most on the Diode direction. Cold joints/other issues for the whole matrix seems a bit unlikely.

hi, thank you for the response, I really appricated
so I did update the “diode_direction” to ROW2COL and it is not working
and looking at the board, I think it is the right proccessor atmega32u4

here is the schematic

but still does seems to work
